description: A Helm chart for Kubernetes
# A chart can be either an 'application' or a 'library' chart.
#
# Application charts are a collection of templates that can be packaged into versioned archives
# to be deployed.
#
# Library charts provide useful utilities or functions for the chart developer. They're included as
# a dependency of application charts to inject those utilities and functions into the rendering
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
type: application
# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 0.1.0
# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
# It is recommended to use it with quotes.

# MinIO
[MinIO](https://min.io) is an object storage server, compatible with Amazon S3 cloud storage service, mainly used for storing unstructured data (such as photos, videos, log files, etc.)
## TL;DR
```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/minio
```
## Introduction
This chart bootstraps a [MinIO](https://github.com/bitnami/bitnami-docker-minio) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.
## Prerequisites
- Kubernetes 1.12+
- Helm 2.12+ or Helm 3.0-beta3+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/minio
```
These commands deploy MinIO on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install my-release \
--set accessKey.password=minio-access-key \
--set secretKey.password=minio-secret-key \
bitnami/minio
```
The above command sets the MinIO Server access key and secret key to `minio-access-key` and `minio-secret-key`, respectively.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```console
$ helm install my-release -f values.yaml bitnami/minio
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Production configuration
This chart includes a `values-production.yaml` file where you can find some parameters oriented to production configuration in comparison to the regular `values.yaml`. You can use this file instead of the default one.
- MinIO server mode:
```diff
- mode: standalone
+ mode: distributed
```
- Disable MinIO Web UI:
```diff
- disableWebUI: false
+ disableWebUI: true
```
- Annotations to be added to pods:
```diff
- podAnnotations: {}
+ podAnnotations:
+ prometheus.io/scrape: "true"
+ prometheus.io/path: "/minio/prometheus/metrics"
+ prometheus.io/port: "9000"
```
- Pod resources:
```diff
- resources: {}
+ resources:
+ requests:
+ memory: 256Mi
+ cpu: 250m
```
- Enable NetworkPolicy:
```diff
- networkPolicy.enabled: false
+ networkPolicy.enabled: true
```
- Don't require client label for connections:
```diff
- networkPolicy.allowExternal: true
+ networkPolicy.allowExternal: false
```
- Change Prometheus authentication:
```diff
- prometheusAuthType: public
+ prometheusAuthType: jwt
```
### Distributed mode
You can start the MinIO chart in distributed mode with the following parameter: `mode=distributed`
This chart sets Minio server in distributed mode with 4 nodes by default. You can change the number of nodes setting the `statefulset.replicaCount` parameter, for example to `statefulset.replicaCount=8`
> Note: that the number of replicas must even, greater than 4 and lower than 32
### Prometheus exporter
MinIO exports Prometheus metrics at `/minio/prometheus/metrics`. To allow Prometheus collecting your MinIO metrics, modify the `values.yaml` adding the corresponding annotations:
```diff
- podAnnotations: {}
+ podAnnotations:
+ prometheus.io/scrape: "true"
+ prometheus.io/path: "/minio/prometheus/metrics"
+ prometheus.io/port: "9000"
```
> Find more information about MinIO metrics at https://docs.min.io/docs/how-to-monitor-minio-using-prometheus.html
## Persistence
The [Bitnami MinIO](https://github.com/bitnami/bitnami-docker-minio) image stores data at the `/data` path of the container.
The chart mounts a [Persistent Volume](http://kubernetes.io/docs/user-guide/persistent-volumes/) at this location. The volume is created using dynamic volume provisioning.
### Adjust permissions of persistent volume mountpoint
As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
You can enable this initContainer by setting `volumePermissions.enabled` to `true`.

** Please be patient while the chart is being deployed **
MinIO can be accessed via port {{ .Values.service.port }} on the following DNS name from within your cluster:
{{ include "minio.fullname" . }}.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}
To get your credentials run:
export MINIO_ACCESS_KEY=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ include "minio.fullname" . }} -o jsonpath="{.data.access-key}" | base64 --decode)
export MINIO_SECRET_KEY=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ include "minio.fullname" . }} -o jsonpath="{.data.secret-key}" | base64 --decode)
To connect to your MinIO server using a client:
- Run a MinIO Client pod and append the desired command (e.g. 'admin info server'):
kubectl run --namespace {{ .Release.Namespace }} {{ include "minio.fullname" . }}-client \
--rm --tty -i --restart='Never' \
--env MINIO_SERVER_ACCESS_KEY=$MINIO_ACCESS_KEY \
--env MINIO_SERVER_SECRET_KEY=$MINIO_SECRET_KEY \

{{- end }}
--image {{ template "minio.clientImage" . }} -- admin info server minio
{{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
NOTE: Since NetworkPolicy is enabled, only pods with label
"{{ template "minio.fullname" . }}-client=true" will be able to connect to MinIO.
{{- end }}

# PostgreSQL
[PostgreSQL](https://www.postgresql.org/) is an object-relational database management system (ORDBMS) with an emphasis on extensibility and on standards-compliance.
For HA, please see [this repo](https://github.com/bitnami/charts/tree/master/bitnami/postgresql-ha)
## TL;DR
```console
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/postgresql
```
## Introduction
This chart bootstraps a [PostgreSQL](https://github.com/bitnami/bitnami-docker-postgresql) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the [BKPR](https://kubeprod.io/).
## Prerequisites
- Kubernetes 1.12+
- Helm 2.12+ or Helm 3.0-beta3+
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install my-release bitnami/postgresql
```
The command deploys PostgreSQL on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components but PVC's associated with the chart and deletes the release.
To delete the PVC's associated with `my-release`:
```console
$ kubectl delete pvc -l release=my-release
```
> **Note**: Deleting the PVC's will delete postgresql data as well. Please be cautious before doing it.
## Parameters
The following tables lists the configurable parameters of the PostgreSQL chart and their default values.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```console
$ helm install my-release \
--set postgresqlPassword=secretpassword,postgresqlDatabase=my-database \
bitnami/postgresql
```
The above command sets the PostgreSQL `postgres` account password to `secretpassword`. Additionally it creates a database named `my-database`.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```console
$ helm install my-release -f values.yaml bitnami/postgresql
```
> **Tip**: You can use the default [values.yaml](values.yaml)
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Production configuration and horizontal scaling
This chart includes a `values-production.yaml` file where you can find some parameters oriented to production configuration in comparison to the regular `values.yaml`. You can use this file instead of the default one.
- Enable replication:
```diff
- replication.enabled: false
+ replication.enabled: true
```
- Number of slaves replicas:
```diff
- replication.slaveReplicas: 1
+ replication.slaveReplicas: 2
```
- Set synchronous commit mode:
```diff
- replication.synchronousCommit: "off"
+ replication.synchronousCommit: "on"
```
- Number of replicas that will have synchronous replication:
```diff
- replication.numSynchronousReplicas: 0
+ replication.numSynchronousReplicas: 1
```
- Start a prometheus exporter:
```diff
- metrics.enabled: false
+ metrics.enabled: true
```
To horizontally scale this chart, you can use the `--replicas` flag to modify the number of nodes in your PostgreSQL deployment. Also you can use the `values-production.yaml` file or modify the parameters shown above.
### Customizing Master and Slave services in a replicated configuration
At the top level, there is a service object which defines the services for both master and slave. For deeper customization, there are service objects for both the master and slave types individually. This allows you to override the values in the top level service object so that the master and slave can be of different service types and with different clusterIPs / nodePorts. Also in the case you want the master and slave to be of type nodePort, you will need to set the nodePorts to different values to prevent a collision. The values that are deeper in the master.service or slave.service objects will take precedence over the top level service object.
### Change PostgreSQL version
To modify the PostgreSQL version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/postgresql/tags/) using the `image.tag` parameter. For example, `image.tag=X.Y.Z`. This approach is also applicable to other images like exporters.
### postgresql.conf / pg_hba.conf files as configMap
This helm chart also supports to customize the whole configuration file.
Add your custom file to "files/postgresql.conf" in your working directory. This file will be mounted as configMap to the containers and it will be used for configuring the PostgreSQL server.
Alternatively, you can specify PostgreSQL configuration parameters using the `postgresqlConfiguration` parameter as a dict, using camelCase, e.g. {"sharedBuffers": "500MB"}.
In addition to these options, you can also set an external ConfigMap with all the configuration files. This is done by setting the `configurationConfigMap` parameter. Note that this will override the two previous options.
### Allow settings to be loaded from files other than the default `postgresql.conf`
If you don't want to provide the whole PostgreSQL configuration file and only specify certain parameters, you can add your extended `.conf` files to "files/conf.d/" in your working directory.
Those files will be mounted as configMap to the containers adding/overwriting the default configuration using the `include_dir` directive that allows settings to be loaded from files other than the default `postgresql.conf`.
Alternatively, you can also set an external ConfigMap with all the extra configuration files. This is done by setting the `extendedConfConfigMap` parameter. Note that this will override the previous option.
### Initialize a fresh instance
The [Bitnami PostgreSQL](https://github.com/bitnami/bitnami-docker-postgresql) image allows you to use your custom scripts to initialize a fresh instance. In order to execute the scripts, they must be located inside the chart folder `files/docker-entrypoint-initdb.d` so they can be consumed as a ConfigMap.
Alternatively, you can specify custom scripts using the `initdbScripts` parameter as dict.
In addition to these options, you can also set an external ConfigMap with all the initialization scripts. This is done by setting the `initdbScriptsConfigMap` parameter. Note that this will override the two previous options. If your initialization scripts contain sensitive information such as credentials or passwords, you can use the `initdbScriptsSecret` parameter.
The allowed extensions are `.sh`, `.sql` and `.sql.gz`.
### Securing traffic using TLS
TLS support can be enabled in the chart by specifying the `tls.` parameters while creating a release. The following parameters should be configured to properly enable the TLS support in the chart:
- `tls.enabled`: Enable TLS support. Defaults to `false`
- `tls.certificatesSecret`: Name of an existing secret that contains the certificates. No defaults.
- `tls.certFilename`: Certificate filename. No defaults.
- `tls.certKeyFilename`: Certificate key filename. No defaults.
For example:
* First, create the secret with the cetificates files:
```console
kubectl create secret generic certificates-tls-secret --from-file=./cert.crt --from-file=./cert.key --from-file=./ca.crt
```
* Then, use the following parameters:
```console
volumePermissions.enabled=true
tls.enabled=true
tls.certificatesSecret="certificates-tls-secret"
tls.certFilename="cert.crt"
tls.certKeyFilename="cert.key"
```
> Note TLS and VolumePermissions: PostgreSQL requires certain permissions on sensitive files (such as certificate keys) to start up. Due to an on-going [issue](https://github.com/kubernetes/kubernetes/issues/57923) regarding kubernetes permissions and the use of `containerSecurityContext.runAsUser`, you must enable `volumePermissions` to ensure everything works as expected.
### Sidecars
If you need additional containers to run within the same pod as PostgreSQL (e.g. an additional metrics or logging exporter), you can do so via the `sidecars` config parameter. Simply define your container according to the Kubernetes container spec.
```yaml
# For the PostgreSQL master
master:
sidecars:
- name: your-image-name
image: your-image
imagePullPolicy: Always
ports:
- name: portname
containerPort: 1234
# For the PostgreSQL replicas
slave:
sidecars:
- name: your-image-name
image: your-image
imagePullPolicy: Always
ports:
- name: portname
containerPort: 1234
```
### Metrics
The chart optionally can start a metrics exporter for [prometheus](https://prometheus.io). The metrics endpoint (port 9187) is not exposed and it is expected that the metrics are collected from inside the k8s cluster using something similar as the described in the [example Prometheus scrape configuration](https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml).
The exporter allows to create custom metrics from additional SQL queries. See the Chart's `values.yaml` for an example and consult the [exporters documentation](https://github.com/wrouesnel/postgres_exporter#adding-new-metrics-via-a-config-file) for more details.
### Use of global variables
In more complex scenarios, we may have the following tree of dependencies
```
+--------------+
| |
+------------+ Chart 1 +-----------+
| | | |
| --------+------+ |
| | |
| | |
| | |
| | |
v v v
+-------+------+ +--------+------+ +--------+------+
| | | | | |
| PostgreSQL | | Sub-chart 1 | | Sub-chart 2 |
| | | | | |
+--------------+ +---------------+ +---------------+
```
The three charts below depend on the parent chart Chart 1. However, subcharts 1 and 2 may need to connect to PostgreSQL as well. In order to do so, subcharts 1 and 2 need to know the PostgreSQL credentials, so one option for deploying could be deploy Chart 1 with the following parameters:
```
postgresql.postgresqlPassword=testtest
subchart1.postgresql.postgresqlPassword=testtest
subchart2.postgresql.postgresqlPassword=testtest
postgresql.postgresqlDatabase=db1
subchart1.postgresql.postgresqlDatabase=db1
subchart2.postgresql.postgresqlDatabase=db1
```
If the number of dependent sub-charts increases, installing the chart with parameters can become increasingly difficult. An alternative would be to set the credentials using global variables as follows:
```
global.postgresql.postgresqlPassword=testtest
global.postgresql.postgresqlDatabase=db1
```
This way, the credentials will be available in all of the subcharts.
## Persistence
The [Bitnami PostgreSQL](https://github.com/bitnami/bitnami-docker-postgresql) image stores the PostgreSQL data and configurations at the `/bitnami/postgresql` path of the container.
Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
See the [Parameters](#parameters) section to configure the PVC or to disable persistence.
If you already have data in it, you will fail to sync to standby nodes for all commits, details can refer to [code](https://github.com/bitnami/bitnami-docker-postgresql/blob/8725fe1d7d30ebe8d9a16e9175d05f7ad9260c93/9.6/debian-9/rootfs/libpostgresql.sh#L518-L556). If you need to use those data, please covert them to sql and import after `helm install` finished.
## NetworkPolicy
To enable network policy for PostgreSQL, install [a networking plugin that implements the Kubernetes NetworkPolicy spec](https://kubernetes.io/docs/tasks/administer-cluster/declare-network-policy#before-you-begin), and set `networkPolicy.enabled` to `true`.
For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting the DefaultDeny namespace annotation. Note: this will enforce policy for _all_ pods in the namespace:
```console
$ kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
```
With NetworkPolicy enabled, traffic will be limited to just port 5432.
For more precise policy, set `networkPolicy.allowExternal=false`. This will only allow pods with the generated client label to connect to PostgreSQL.
This label will be displayed in the output of a successful install.
## Differences between Bitnami PostgreSQL image and [Docker Official](https://hub.docker.com/_/postgres) image
- The Docker Official PostgreSQL image does not support replication. If you pass any replication environment variable, this would be ignored. The only environment variables supported by the Docker Official image are POSTGRES_USER, POSTGRES_DB, POSTGRES_PASSWORD, POSTGRES_INITDB_ARGS, POSTGRES_INITDB_WALDIR and PGDATA. All the remaining environment variables are specific to the Bitnami PostgreSQL image.
- The Bitnami PostgreSQL image is non-root by default. This requires that you run the pod with `securityContext` and updates the permissions of the volume with an `initContainer`. A key benefit of this configuration is that the pod follows security best practices and is prepared to run on Kubernetes distributions with hard security constraints like OpenShift.
- For OpenShift, one may either define the runAsUser and fsGroup accordingly, or try this more dynamic option: volumePermissions.securityContext.runAsUser="auto",securityContext.enabled=false,containerSecurityContext.enabled=false,shmVolume.chmod.enabled=false
### Deploy chart using Docker Official PostgreSQL Image
From chart version 4.0.0, it is possible to use this chart with the Docker Official PostgreSQL image.
Besides specifying the new Docker repository and tag, it is important to modify the PostgreSQL data directory and volume mount point. Basically, the PostgreSQL data dir cannot be the mount point directly, it has to be a subdirectory.
```
image.repository=postgres
image.tag=10.6
postgresqlDataDir=/data/pgdata
persistence.mountPath=/data/
```
## Upgrade
It's necessary to specify the existing passwords while performing an upgrade to ensure the secrets are not updated with invalid randomly generated passwords. Remember to specify the existing values of the `postgresqlPassword` and `replication.password` parameters when upgrading the chart:
```bash
$ helm upgrade my-release stable/postgresql \
--set postgresqlPassword=[POSTGRESQL_PASSWORD] \
--set replication.password=[REPLICATION_PASSWORD]
```
> Note: you need to substitute the placeholders _[POSTGRESQL_PASSWORD]_, and _[REPLICATION_PASSWORD]_ with the values obtained from instructions in the installation notes.
## 9.0.0
In this version the chart was adapted to follow the Helm label best practices, see [PR 3021](https://github.com/bitnami/charts/pull/3021). That means the backward compatibility is not guarantee when upgrading the chart to this major version.
As a workaround, you can delete the existing statefulset (using the `--cascade=false` flag pods are not deleted) before upgrade the chart. For example, this can be a valid workflow:
- Deploy an old version (8.X.X)
```console
$ helm install postgresql bitnami/postgresql --version 8.10.14
```
- Old version is up and running
```console
$ helm ls
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
postgresql default 1 2020-08-04 13:39:54.783480286 +0000 UTC deployed postgresql-8.10.14 11.8.0
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
postgresql-postgresql-0 1/1 Running 0 76s
```
- The upgrade to the latest one (9.X.X) is going to fail
```console
$ helm upgrade postgresql bitnami/postgresql
Error: UPGRADE FAILED: cannot patch "postgresql-postgresql" with kind StatefulSet: StatefulSet.apps "postgresql-postgresql" is invalid: spec: Forbidden: updates to statefulset spec for fields other than 'replicas', 'template', and 'updateStrategy' are forbidden
```
- Delete the statefulset
```console
$ kubectl delete statefulsets.apps --cascade=false postgresql-postgresql
statefulset.apps "postgresql-postgresql" deleted
```
- Now the upgrade works
```cosnole
$ helm upgrade postgresql bitnami/postgresql
$ helm ls
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
postgresql default 3 2020-08-04 13:42:08.020385884 +0000 UTC deployed postgresql-9.1.2 11.8.0
```
- We can kill the existing pod and the new statefulset is going to create a new one:
```console
$ kubectl delete pod postgresql-postgresql-0
pod "postgresql-postgresql-0" deleted
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
postgresql-postgresql-0 1/1 Running 0 19s
```
Please, note that without the `--cascade=false` both objects (statefulset and pod) are going to be removed and both objects will be deployed again with the `helm upgrade` command
## 8.0.0
Prefixes the port names with their protocols to comply with Istio conventions.
If you depend on the port names in your setup, make sure to update them to reflect this change.
## 7.1.0
Adds support for LDAP configuration.
## 7.0.0
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In https://github.com/helm/charts/pull/17281 the `apiVersion` of the statefulset resources was updated to `apps/v1` in tune with the api's deprecated, resulting in compatibility breakage.
This major version bump signifies this change.
## 6.5.7
In this version, the chart will use PostgreSQL with the Postgis extension included. The version used with Postgresql version 10, 11 and 12 is Postgis 2.5. It has been compiled with the following dependencies:
- protobuf
- protobuf-c
- json-c
- geos
- proj
## 5.0.0
In this version, the **chart is using PostgreSQL 11 instead of PostgreSQL 10**. You can find the main difference and notable changes in the following links: [https://www.postgresql.org/about/news/1894/](https://www.postgresql.org/about/news/1894/) and [https://www.postgresql.org/about/featurematrix/](https://www.postgresql.org/about/featurematrix/).
For major releases of PostgreSQL, the internal data storage format is subject to change, thus complicating upgrades, you can see some errors like the following one in the logs:

[1] FATAL: database files are incompatible with server
[1] DETAIL: The data directory was initialized by PostgreSQL version 10, which is not compatible with this version 11.3.
```
In this case, you should migrate the data from the old chart to the new one following an approach similar to that described in [this section](https://www.postgresql.org/docs/current/upgrading.html#UPGRADING-VIA-PGDUMPALL) from the official documentation. Basically, create a database dump in the old chart, move and restore it in the new one.
### 4.0.0
This chart will use by default the Bitnami PostgreSQL container starting from version `10.7.0-r68`. This version moves the initialization logic from node.js to bash. This new version of the chart requires setting the `POSTGRES_PASSWORD` in the slaves as well, in order to properly configure the `pg_hba.conf` file. Users from previous versions of the chart are advised to upgrade immediately.
IMPORTANT: If you do not want to upgrade the chart version then make sure you use the `10.7.0-r68` version of the container. Otherwise, you will get this error
```
The POSTGRESQL_PASSWORD environment variable is empty or not set. Set the environment variable ALLOW_EMPTY_PASSWORD=yes to allow the container to be started with blank passwords. This is recommended only for development
```
### 3.0.0
This releases make it possible to specify different nodeSelector, affinity and tolerations for master and slave pods.
It also fixes an issue with `postgresql.master.fullname` helper template not obeying fullnameOverride.
#### Breaking changes
- `affinty` has been renamed to `master.affinity` and `slave.affinity`.
- `tolerations` has been renamed to `master.tolerations` and `slave.tolerations`.
- `nodeSelector` has been renamed to `master.nodeSelector` and `slave.nodeSelector`.
### 2.0.0
In order to upgrade from the `0.X.X` branch to `1.X.X`, you should follow the below steps:
- Obtain the service name (`SERVICE_NAME`) and password (`OLD_PASSWORD`) of the existing postgresql chart. You can find the instructions to obtain the password in the NOTES.txt, the service name can be obtained by running
```console
$ kubectl get svc
```
- Install (not upgrade) the new version
```console
$ helm repo update
$ helm install my-release bitnami/postgresql
```
- Connect to the new pod (you can obtain the name by running `kubectl get pods`):
```console
$ kubectl exec -it NAME bash
```
- Once logged in, create a dump file from the previous database using `pg_dump`, for that we should connect to the previous postgresql chart:
```console
$ pg_dump -h SERVICE_NAME -U postgres DATABASE_NAME > /tmp/backup.sql
```
After run above command you should be prompted for a password, this password is the previous chart password (`OLD_PASSWORD`).
This operation could take some time depending on the database size.
- Once you have the backup file, you can restore it with a command like the one below:
```console
$ psql -U postgres DATABASE_NAME < /tmp/backup.sql
```
In this case, you are accessing to the local postgresql, so the password should be the new one (you can find it in NOTES.txt).
If you want to restore the database and the database schema does not exist, it is necessary to first follow the steps described below.
```console
$ psql -U postgres
postgres=# drop database DATABASE_NAME;
postgres=# create database DATABASE_NAME;
postgres=# create user USER_NAME;
postgres=# alter role USER_NAME with password 'BITNAMI_USER_PASSWORD';
postgres=# grant all privileges on database DATABASE_NAME to USER_NAME;
postgres=# alter database DATABASE_NAME owner to USER_NAME;
```

## Introduction
This chart provides a common template helpers which can be used to develop new charts using [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.

#### Example of use
When we store sensitive data for a deployment in a secret, some times we want to give to users the possibility of using theirs existing secrets.
```yaml
# templates/secret.yaml
---
apiVersion: v1
kind: Secret
metadata:
name: {{ include "common.names.fullname" . }}
labels:
app: {{ include "common.names.fullname" . }}
type: Opaque
data:
password: {{ .Values.password | b64enc | quote }}
# templates/dpl.yaml
---
...
env:
- name: PASSWORD
valueFrom:
secretKeyRef:
name: {{ include "common.secrets.name" (dict "existingSecret" .Values.existingSecret "context" $) }}
key: {{ include "common.secrets.key" (dict "existingSecret" .Values.existingSecret "key" "password") }}
...
# values.yaml
---
name: mySecret
keyMapping:
password: myPasswordKey
```
### ValidateValue
#### NOTES.txt
```console
{{- $validateValueConf00 := (dict "valueKey" "path.to.value00" "secret" "secretName" "field" "password-00") -}}
{{- $validateValueConf01 := (dict "valueKey" "path.to.value01" "secret" "secretName" "field" "password-01") -}}
{{ include "common.validations.values.multiple.empty" (dict "required" (list $validateValueConf00 $validateValueConf01) "context" $) }}
```
If we force those values to be empty we will see some alerts
```console
$ helm install test mychart --set path.to.value00="",path.to.value01=""
'path.to.value00' must not be empty, please add '--set path.to.value00=$PASSWORD_00' to the command. To get the current value:
export PASSWORD_00=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-00}" | base64 --decode)
'path.to.value01' must not be empty, please add '--set path.to.value01=$PASSWORD_01' to the command. To get the current value:
export PASSWORD_01=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-01}" | base64 --decode)
```

** Please be patient while the chart is being deployed **
PostgreSQL can be accessed via port {{ template "postgresql.port" . }} on the following DNS name from within your cluster:
{{ template "postgresql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local - Read/Write connection
{{- if .Values.replication.enabled }}
{{ template "postgresql.fullname" . }}-read.{{ .Release.Namespace }}.svc.cluster.local - Read only connection
{{- end }}
{{- if and (not (eq .Values.postgresqlUsername "postgres")) (or .Values.postgresqlPostgresPassword (include "postgresql.useExistingSecret" .)) }}
To get the password for "postgres" run:
export POSTGRES_ADMIN_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.secretName" . }} -o jsonpath="{.data.postgresql-postgres-password}" | base64 --decode)
{{- end }}
To get the password for "{{ template "postgresql.username" . }}" run:
export POSTGRES_PASSWORD=$(kubectl get secret --namespace {{ .Release.Namespace }} {{ template "postgresql.secretName" . }} -o jsonpath="{.data.postgresql-password}" | base64 --decode)
To connect to your database run the following command:
kubectl run {{ template "postgresql.fullname" . }}-client --rm --tty -i --restart='Never' --namespace {{ .Release.Namespace }} --image {{ template "postgresql.image" . }} --env="PGPASSWORD=$POSTGRES_PASSWORD" {{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}

{{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
Note: Since NetworkPolicy is enabled, only pods with label {{ template "postgresql.fullname" . }}-client=true" will be able to connect to this PostgreSQL cluster.
{{- end }}
To connect to your database from outside the cluster execute the following commands:
{{- if contains "NodePort" .Values.service.type }}
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "postgresql.fullname" . }})

{{- else if contains "LoadBalancer" .Values.service.type }}
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
Watch the status with: 'kubectl get svc --namespace {{ .Release.Namespace }} -w {{ template "postgresql.fullname" . }}'
export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "postgresql.fullname" . }} --template "{{"{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}"}}")

## When runAsUser is set to special value "auto", init container will try to chwon the
## data folder to autodetermined user&group, using commands: `id -u`:`id -G | cut -d" " -f2`
## "auto" is especially useful for OpenShift which has scc with dynamic userids (and 0 is not allowed).
## You may want to use this volumePermissions.securityContext.runAsUser="auto" in combination with
## pod securityContext.enabled=false and shmVolume.chmod.enabled=false

# Redis<sup>TM</sup> Chart packaged by Bitnami
[Redis<sup>TM</sup>](http://redis.io/) is an advanced key-value cache and store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs.
Disclaimer: REDIS® is a registered trademark of Redis Labs Ltd.Any rights therein are reserved to Redis Labs Ltd. Any use by Bitnami is for referential purposes only and does not indicate any sponsorship, endorsement, or affiliation between Redis Labs Ltd.
## TL;DR
```bash
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/redis
```
## Introduction
This chart bootstraps a [Redis<sup>TM</sup>](https://github.com/bitnami/bitnami-docker-redis) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the [BKPR](https://kubeprod.io/).
### Choose between Redis<sup>TM</sup> Helm Chart and Redis<sup>TM</sup> Cluster Helm Chart
You can choose any of the two Redis<sup>TM</sup> Helm charts for deploying a Redis<sup>TM</sup> cluster.
While [Redis<sup>TM</sup> Helm Chart](https://github.com/bitnami/charts/tree/master/bitnami/redis) will deploy a master-slave cluster using Redis<sup>TM</sup> Sentinel, the [Redis<sup>TM</sup> Cluster Helm Chart](https://github.com/bitnami/charts/tree/master/bitnami/redis-cluster) will deploy a Redis<sup>TM</sup> Cluster topology with sharding.
The main features of each chart are the following:
| Redis<sup>TM</sup> | Redis<sup>TM</sup> Cluster |
|--------------------------------------------------------|------------------------------------------------------------------------|
| Supports multiple databases | Supports only one database. Better if you have a big dataset |
| Single write point (single master) | Multiple write points (multiple masters) |
| ![Redis<sup>TM</sup> Topology](img/redis-topology.png) | ![Redis<sup>TM</sup> Cluster Topology](img/redis-cluster-topology.png) |
## Prerequisites
- Kubernetes 1.12+
- Helm 3.1.0
- PV provisioner support in the underlying infrastructure
## Installing the Chart
To install the chart with the release name `my-release`:
```bash
$ helm install my-release bitnami/redis
```
The command deploys Redis<sup>TM</sup> on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
> **Tip**: List all releases using `helm list`
## Uninstalling the Chart
To uninstall/delete the `my-release` deployment:
```bash
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.
## Parameters
The following table lists the configurable parameters of the Redis<sup>TM</sup> chart and their default values.
| Parameter | Description | Default |

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```bash
$ helm install my-release \
--set password=secretpassword \
bitnami/redis
```
The above command sets the Redis<sup>TM</sup> server password to `secretpassword`.
> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
```bash
$ helm install my-release -f values.yaml bitnami/redis
```
> **Tip**: You can use the default [values.yaml](values.yaml)
> **Note for minikube users**: Current versions of minikube (v0.24.1 at the time of writing) provision `hostPath` persistent volumes that are only writable by root. Using chart defaults cause pod failure for the Redis<sup>TM</sup> pod as it attempts to write to the `/bitnami` directory. Consider installing Redis<sup>TM</sup> with `--set persistence.enabled=false`. See minikube issue [1990](https://github.com/kubernetes/minikube/issues/1990) for more information.
## Configuration and installation details
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
### Change Redis<sup>TM</sup> version
To modify the Redis<sup>TM</sup> version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/redis/tags/) using the `image.tag` parameter. For example, `image.tag=X.Y.Z`. This approach is also applicable to other images like exporters.
### Cluster topologies
#### Default: Master-Slave
When installing the chart with `cluster.enabled=true`, it will deploy a Redis<sup>TM</sup> master StatefulSet (only one master node allowed) and a Redis<sup>TM</sup> slave StatefulSet. The slaves will be read-replicas of the master. Two services will be exposed:
- Redis<sup>TM</sup> Master service: Points to the master, where read-write operations can be performed
- Redis<sup>TM</sup> Slave service: Points to the slaves, where only read operations are allowed.
In case the master crashes, the slaves will wait until the master node is respawned again by the Kubernetes Controller Manager.
#### Master-Slave with Sentinel
When installing the chart with `cluster.enabled=true` and `sentinel.enabled=true`, it will deploy a Redis<sup>TM</sup> master StatefulSet (only one master allowed) and a Redis<sup>TM</sup> slave StatefulSet. In this case, the pods will contain an extra container with Redis<sup>TM</sup> Sentinel. This container will form a cluster of Redis<sup>TM</sup> Sentinel nodes, which will promote a new master in case the actual one fails. In addition to this, only one service is exposed:
- Redis<sup>TM</sup> service: Exposes port 6379 for Redis<sup>TM</sup> read-only operations and port 26379 for accessing Redis<sup>TM</sup> Sentinel.
For read-only operations, access the service using port 6379. For write operations, it's necessary to access the Redis<sup>TM</sup> Sentinel cluster and query the current master using the command below (using redis-cli or similar:
```
SENTINEL get-master-addr-by-name <name of your MasterSet. Example: mymaster>
```
This command will return the address of the current master, which can be accessed from inside the cluster.
In case the current master crashes, the Sentinel containers will elect a new master node.
### Using password file
To use a password file for Redis<sup>TM</sup> you need to create a secret containing the password.
> *NOTE*: It is important that the file with the password must be called `redis-password`
And then deploy the Helm Chart using the secret name as parameter:
```console
usePassword=true
usePasswordFile=true
existingSecret=redis-password-file
sentinels.enabled=true
metrics.enabled=true
```
### Securing traffic using TLS
TLS support can be enabled in the chart by specifying the `tls.` parameters while creating a release. The following parameters should be configured to properly enable the TLS support in the chart:
- `tls.enabled`: Enable TLS support. Defaults to `false`
- `tls.certificatesSecret`: Name of the secret that contains the certificates. No defaults.
- `tls.certFilename`: Certificate filename. No defaults.
- `tls.certKeyFilename`: Certificate key filename. No defaults.
- `tls.certCAFilename`: CA Certificate filename. No defaults.
For example:
First, create the secret with the certificates files:
```console
kubectl create secret generic certificates-tls-secret --from-file=./cert.pem --from-file=./cert.key --from-file=./ca.pem
```
Then, use the following parameters:
```console
tls.enabled="true"
tls.certificatesSecret="certificates-tls-secret"
tls.certFilename="cert.pem"
tls.certKeyFilename="cert.key"
tls.certCAFilename="ca.pem"
```
### Metrics
The chart optionally can start a metrics exporter for [prometheus](https://prometheus.io). The metrics endpoint (port 9121) is exposed in the service. Metrics can be scraped from within the cluster using something similar as the described in the [example Prometheus scrape configuration](https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml). If metrics are to be scraped from outside the cluster, the Kubernetes API proxy can be utilized to access the endpoint.
If you have enabled TLS by specifying `tls.enabled=true` you also need to specify TLS option to the metrics exporter. You can do that via `metrics.extraArgs`. You can find the metrics exporter CLI flags for TLS [here](https://github.com/oliver006/redis_exporter#command-line-flags). For example:
You can either specify `metrics.extraArgs.skip-tls-verification=true` to skip TLS verification or providing the following values under `metrics.extraArgs` for TLS client authentication:
```console
tls-client-key-file
tls-client-cert-file
tls-ca-cert-file
```
### Host Kernel Settings
Redis<sup>TM</sup> may require some changes in the kernel of the host machine to work as expected, in particular increasing the `somaxconn` value and disabling transparent huge pages.
To do so, you can set up a privileged initContainer with the `sysctlImage` config values, for example:
```
sysctlImage:
enabled: true
mountHostSys: true
command:
- /bin/sh
- -c
- |-
sysctl -w net.core.somaxconn=10000
echo never > /host-sys/kernel/mm/transparent_hugepage/enabled
```
Alternatively, for Kubernetes 1.12+ you can set `securityContext.sysctls` which will configure sysctls for master and slave pods. Example:
```yaml
securityContext:
sysctls:
- name: net.core.somaxconn
value: "10000"
```
Note that this will not disable transparent huge tables.
## Persistence
By default, the chart mounts a [Persistent Volume](http://kubernetes.io/docs/user-guide/persistent-volumes/) at the `/data` path. The volume is created using dynamic volume provisioning. If a Persistent Volume Claim already exists, specify it during installation.
### Existing PersistentVolumeClaim
1. Create the PersistentVolume
2. Create the PersistentVolumeClaim
3. Install the chart
```bash
$ helm install my-release --set persistence.existingClaim=PVC_NAME bitnami/redis
```
## Backup and restore
### Backup
To perform a backup you will need to connect to one of the nodes and execute:
```bash
$ kubectl exec -it my-redis-master-0 bash
$ redis-cli
127.0.0.1:6379> auth your_current_redis_password
OK
127.0.0.1:6379> save
OK
```
Then you will need to get the created dump file form the redis node:
```bash
$ kubectl cp my-redis-master-0:/data/dump.rdb dump.rdb -c redis
```
### Restore
To restore in a new cluster, you will need to change a parameter in the redis.conf file and then upload the `dump.rdb` to the volume.
Follow the following steps:
- First you will need to set in the `values.yaml` the parameter `appendonly` to `no`, if it is already `no` you can skip this step.
```yaml
configmap: |-
# Enable AOF https://redis.io/topics/persistence#append-only-file
appendonly no
# Disable RDB persistence, AOF persistence already enabled.
save ""
```
- Start the new cluster to create the PVCs.
For example, :
```bash
helm install new-redis -f values.yaml . --set cluster.enabled=true --set cluster.slaveCount=3
```
- Now that the PVC were created, stop it and copy the `dump.rdp` on the persisted data by using a helping pod.
```
$ helm delete new-redis
$ kubectl run --generator=run-pod/v1 -i --rm --tty volpod --overrides='
{
"apiVersion": "v1",
"kind": "Pod",
"metadata": {
"name": "redisvolpod"
},
"spec": {
"containers": [{
"command": [
"tail",
"-f",
"/dev/null"
],
"image": "bitnami/minideb",
"name": "mycontainer",
"volumeMounts": [{
"mountPath": "/mnt",
"name": "redisdata"
}]
}],
"restartPolicy": "Never",
"volumes": [{
"name": "redisdata",
"persistentVolumeClaim": {
"claimName": "redis-data-new-redis-master-0"
}
}]
}
}' --image="bitnami/minideb"
$ kubectl cp dump.rdb redisvolpod:/mnt/dump.rdb
$ kubectl delete pod volpod
```
- Start again the cluster:
```
helm install new-redis -f values.yaml . --set cluster.enabled=true --set cluster.slaveCount=3
```
## NetworkPolicy
To enable network policy for Redis<sup>TM</sup>, install
[a networking plugin that implements the Kubernetes NetworkPolicy spec](https://kubernetes.io/docs/tasks/administer-cluster/declare-network-policy#before-you-begin),
and set `networkPolicy.enabled` to `true`.
For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting
the DefaultDeny namespace annotation. Note: this will enforce policy for _all_ pods in the namespace:
kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"
With NetworkPolicy enabled, only pods with the generated client label will be
able to connect to Redis<sup>TM</sup>. This label will be displayed in the output
after a successful install.
With `networkPolicy.ingressNSMatchLabels` pods from other namespaces can connect to redis. Set `networkPolicy.ingressNSPodMatchLabels` to match pod labels in matched namespace. For example, for a namespace labeled `redis=external` and pods in that namespace labeled `redis-client=true` the fields should be set:
```
networkPolicy:
enabled: true
ingressNSMatchLabels:
redis: external
ingressNSPodMatchLabels:
redis-client: true
```

## Upgrading an existing Release to a new major version
A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an
incompatible breaking change needing manual actions.
### To 11.0.0
When using sentinel, a new statefulset called `-node` was introduced. This will break upgrading from a previous version where the statefulsets are called master and slave. Hence the PVC will not match the new naming and won't be reused. If you want to keep your data, you will need to perform a backup and then a restore the data in this new version.
### To 10.0.0
For releases with `usePassword: true`, the value `sentinel.usePassword` controls whether the password authentication also applies to the sentinel port. This defaults to `true` for a secure configuration, however it is possible to disable to account for the following cases:
- Using a version of redis-sentinel prior to `5.0.1` where the authentication feature was introduced.
- Where redis clients need to be updated to support sentinel authentication.
If using a master/slave topology, or with `usePassword: false`, no action is required.
### To 8.0.18
For releases with `metrics.enabled: true` the default tag for the exporter image is now `v1.x.x`. This introduces many changes including metrics names. You'll want to use [this dashboard](https://github.com/oliver006/redis_exporter/blob/master/contrib/grafana_prometheus_redis_dashboard.json) now. Please see the [redis_exporter github page](https://github.com/oliver006/redis_exporter#upgrading-from-0x-to-1x) for more details.
### To 7.0.0
This version causes a change in the Redis<sup>TM</sup> Master StatefulSet definition, so the command helm upgrade would not work out of the box. As an alternative, one of the following could be done:
- Recommended: Create a clone of the Redis<sup>TM</sup> Master PVC (for example, using projects like [this one](https://github.com/edseymour/pvc-transfer)). Then launch a fresh release reusing this cloned PVC.
```
helm install my-release bitnami/redis --set persistence.existingClaim=<NEW PVC>
```
- Alternative (not recommended, do at your own risk): `helm delete --purge` does not remove the PVC assigned to the Redis<sup>TM</sup> Master StatefulSet. As a consequence, the following commands can be done to upgrade the release
```
helm delete --purge <RELEASE>
helm install <RELEASE> bitnami/redis
```
Previous versions of the chart were not using persistence in the slaves, so this upgrade would add it to them. Another important change is that no values are inherited from master to slaves. For example, in 6.0.0 `slaves.readinessProbe.periodSeconds`, if empty, would be set to `master.readinessProbe.periodSeconds`. This approach lacked transparency and was difficult to maintain. From now on, all the slave parameters must be configured just as it is done with the masters.
Some values have changed as well:
- `master.port` and `slave.port` have been changed to `redisPort` (same value for both master and slaves)
- `master.securityContext` and `slave.securityContext` have been changed to `securityContext`(same values for both master and slaves)
By default, the upgrade will not change the cluster topology. In case you want to use Redis<sup>TM</sup> Sentinel, you must explicitly set `sentinel.enabled` to `true`.
### To 6.0.0
Previous versions of the chart were using an init-container to change the permissions of the volumes. This was done in case the `securityContext` directive in the template was not enough for that (for example, with cephFS). In this new version of the chart, this container is disabled by default (which should not affect most of the deployments). If your installation still requires that init container, execute `helm upgrade` with the `--set volumePermissions.enabled=true`.
### To 5.0.0
The default image in this release may be switched out for any image containing the `redis-server`
and `redis-cli` binaries. If `redis-server` is not the default image ENTRYPOINT, `master.command`
must be specified.
#### Breaking changes
- `master.args` and `slave.args` are removed. Use `master.command` or `slave.command` instead in order to override the image entrypoint, or `master.extraFlags` to pass additional flags to `redis-server`.
- `disableCommands` is now interpreted as an array of strings instead of a string of comma separated values.
- `master.persistence.path` now defaults to `/data`.
### 4.0.0
This version removes the `chart` label from the `spec.selector.matchLabels`
which is immutable since `StatefulSet apps/v1beta2`. It has been inadvertently
added, causing any subsequent upgrade to fail. See https://github.com/helm/charts/issues/7726.
It also fixes https://github.com/helm/charts/issues/7726 where a deployment `extensions/v1beta1` can not be upgraded if `spec.selector` is not explicitly set.
Finally, it fixes https://github.com/helm/charts/issues/7803 by removing mutable labels in `spec.VolumeClaimTemplate.metadata.labels` so that it is upgradable.
In order to upgrade, delete the Redis<sup>TM</sup> StatefulSet before upgrading:
```bash
kubectl delete statefulsets.apps --cascade=false my-release-redis-master
```
And edit the Redis<sup>TM</sup> slave (and metrics if enabled) deployment:
```bash
kubectl patch deployments my-release-redis-slave --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
kubectl patch deployments my-release-redis-metrics --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
```
## Upgrading
### To 12.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
**What changes were introduced in this major version?**
- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
**Considerations when upgrading to this version**
- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

- https://helm.sh/docs/topics/v2_v3_migration/
- https://helm.sh/blog/migrate-from-helm-v2-to-helm-v3/
### To 11.0.0
When deployed with sentinel enabled, only a group of nodes is deployed and the master/slave role is handled in the group. To avoid breaking the compatibility, the settings for this nodes are given through the `slave.xxxx` parameters in `values.yaml`
### To 9.0.0
The metrics exporter has been changed from a separate deployment to a sidecar container, due to the latest changes in the Redis<sup>TM</sup> exporter code. Check the [official page](https://github.com/oliver006/redis_exporter/) for more information. The metrics container image was changed from oliver006/redis_exporter to bitnami/redis-exporter (Bitnami's maintained package of oliver006/redis_exporter).
### To 7.0.0
In order to improve the performance in case of slave failure, we added persistence to the read-only slaves. That means that we moved from Deployment to StatefulSets. This should not affect upgrades from previous versions of the chart, as the deployments did not contain any persistence at all.
This version also allows enabling Redis<sup>TM</sup> Sentinel containers inside of the Redis<sup>TM</sup> Pods (feature disabled by default). In case the master crashes, a new Redis<sup>TM</sup> node will be elected as master. In order to query the current master (no redis master service is exposed), you need to query first the Sentinel cluster. Find more information [in this section](#master-slave-with-sentinel).

```
If we force those values to be empty we will see some alerts
```console
$ helm install test mychart --set path.to.value00="",path.to.value01=""
'path.to.value00' must not be empty, please add '--set path.to.value00=$PASSWORD_00' to the command. To get the current value:
export PASSWORD_00=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-00}" | base64 --decode)
'path.to.value01' must not be empty, please add '--set path.to.value01=$PASSWORD_01' to the command. To get the current value:
export PASSWORD_01=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-01}" | base64 --decode)
```
## Upgrading
### To 1.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
**What changes were introduced in this major version?**
- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Use `type: library`. [Here](https://v3.helm.sh/docs/faq/#library-chart-support) you can find more information.
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
**Considerations when upgrading to this version**
- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
