# Redis™ Chart packaged by Bitnami
[Redis™](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™](https://github.com/bitnami/bitnami-docker-redis) deployment on a [Kubernetes](https://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™ Helm Chart and Redis™ Cluster Helm Chart
You can choose any of the two Redis™ Helm charts for deploying a Redis™ cluster.
1. [Redis™ Helm Chart](https://github.com/bitnami/charts/tree/master/bitnami/redis) will deploy a master-slave cluster, with the [option](https://github.com/bitnami/charts/tree/master/bitnami/redis#redistm-sentinel-configuration-parameters) of enabling using Redis™ Sentinel.
2. [Redis™ Cluster Helm Chart](https://github.com/bitnami/charts/tree/master/bitnami/redis-cluster) will deploy a Redis™ Cluster topology with sharding.
The main features of each chart are the following:
| Redis™ | Redis™ 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™ Topology](img/redis-topology.png) | ![Redis™ 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™ 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.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
```bash
$ helm install my-release \
--set auth.password=secretpassword \
bitnami/redis
```
The above command sets the Redis™ 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)
## 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.
### Use a different Redis™ version
To modify the application version used in this chart, specify a different version of the image using the `image.tag` parameter and/or a different repository using the `image.repository` parameter. Refer to the [chart documentation for more information on these parameters and how to use them with images from a private registry](https://docs.bitnami.com/kubernetes/infrastructure/redis/configuration/change-image-version/).
### Cluster topologies
#### Default: Master-Replicas
When installing the chart with `architecture=replication`, it will deploy a Redis™ master StatefulSet (only one master node allowed) and a Redis™ replicas StatefulSet. The replicas will be read-replicas of the master. Two services will be exposed:
- Redis™ Master service: Points to the master, where read-write operations can be performed
- Redis™ Replicas service: Points to the replicas, where only read operations are allowed.
In case the master crashes, the replicas will wait until the master node is respawned again by the Kubernetes Controller Manager.
#### Standalone
When installing the chart with `architecture=standalone`, it will deploy a standalone Redis™ StatefulSet (only one node allowed) and a Redis™ replicas StatefulSet. A single service will be exposed:
- Redis™ Master service: Points to the master, where read-write operations can be performed
#### Master-Replicas with Sentinel
When installing the chart with `architecture=replication` and `sentinel.enabled=true`, it will deploy a Redis™ master StatefulSet (only one master allowed) and a Redis™ replicas StatefulSet. In this case, the pods will contain an extra container with Redis™ Sentinel. This container will form a cluster of Redis™ Sentinel nodes, which will promote a new master in case the actual one fails. In addition to this, only one service is exposed:
- Redis™ service: Exposes port 6379 for Redis™ read-only operations and port 26379 for accessing Redis™ Sentinel.
For read-only operations, access the service using port 6379. For write operations, it's necessary to access the Redis™ 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. e.g: 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 a password file
To use a password file for Redis&trade; you need to create a secret containing the password and then deploy the chart using that secret.
Refer to the chart documentation for more information on [using a password file for Redis&trade;](https://docs.bitnami.com/kubernetes/infrastructure/redis/administration/use-password-file/).
### 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.existingSecret`: 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.
Refer to the chart documentation for more information on [creating the secret and a TLS deployment example](https://docs.bitnami.com/kubernetes/infrastructure/redis/administration/enable-tls/).
### 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&trade; 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.
Refer to the chart documentation for more information on [configuring host kernel settings with an example](https://docs.bitnami.com/kubernetes/infrastructure/redis/administration/configure-kernel-settings/).
## Persistence
By default, the chart mounts a [Persistent Volume](https://kubernetes.io/docs/concepts/storage/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 master.persistence.existingClaim=PVC_NAME bitnami/redis
```
## Backup and restore
Refer to the chart documentation for more information on [backing up and restoring Redis&trade; deployments](https://docs.bitnami.com/kubernetes/infrastructure/redis/administration/backup-restore/).
## NetworkPolicy
To enable network policy for Redis&trade;, 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`.
Refer to the chart documenation for more information on [enabling the network policy in Redis&trade; deployments](https://docs.bitnami.com/kubernetes/infrastructure/redis/administration/enable-network-policy/).
### Setting Pod's affinity
This chart allows you to set your custom affinity using the `XXX.affinity` parameter(s). Find more infomation about Pod's affinity in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.
## Troubleshooting
Find more information about how to deal with common errors related to Bitnami’s Helm charts in [this troubleshooting guide](https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues).
## Upgrading
A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an incompatible breaking change needing manual actions.
### To 15.0.0
The parameter to enable the usage of StaticIDs was removed. The behavior is to [always use StaticIDs](https://github.com/bitnami/charts/pull/7278).
### To 14.8.0
The Redis&trade; sentinel exporter was removed in this version because the upstream project was deprecated. The regular Redis&trade; exporter is included in the sentinel scenario as usual.
### To 14.0.0
- Several parameters were renamed or disappeared in favor of new ones on this major version:
- The term *slave* has been replaced by the term *replica*. Therefore, parameters prefixed with `slave` are now prefixed with `replicas`.
- Credentials parameter are reorganized under the `auth` parameter.
- `cluster.enabled` parameter is deprecated in favor of `architecture` parameter that accepts two values: `standalone` and `replication`.
- `securityContext.*` is deprecated in favor of `XXX.podSecurityContext` and `XXX.containerSecurityContext`.
- `sentinel.metrics.*` parameters are deprecated in favor of `metrics.sentinel.*` ones.
- New parameters to add custom command, environment variables, sidecars, init containers, etc. were added.
- Chart labels were adapted to follow the [Helm charts standard labels](https://helm.sh/docs/chart_best_practices/labels/#standard-labels).
- values.yaml metadata was adapted to follow the format supported by [Readme Generator for Helm](https://github.com/bitnami-labs/readme-generator-for-helm).
Consequences:
Backwards compatibility is not guaranteed. To upgrade to `14.0.0`, install a new release of the Redis&trade; chart, and migrate the data from your previous release. You have 2 alternatives to do so:
- Create a backup of the database, and restore it on the new release as explained in the [Backup and restore](#backup-and-restore) section.
- Reuse the PVC used to hold the master data on your previous release. To do so, use the `master.persistence.existingClaim` parameter. The following example assumes that the release name is `redis`:
```bash
$ helm install redis bitnami/redis --set auth.password=[PASSWORD] --set master.persistence.existingClaim=[EXISTING_PVC]
```
| Note: you need to substitute the placeholder _[EXISTING_PVC]_ with the name of the PVC used on your previous release, and _[PASSWORD]_ with the password used in your previous release.
### To 13.0.0
This major version updates the Redis&trade; docker image version used from `6.0` to `6.2`, the new stable version. There are no major changes in the chart and there shouldn't be any breaking changes in it as `6.2` is basically a stricter superset of `6.0`. For more information, please refer to [Redis&trade; 6.2 release notes](https://raw.githubusercontent.com/redis/redis/6.2/00-RELEASENOTES).
### To 12.3.0
This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/master/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
### 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&trade; 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&trade; Sentinel containers inside of the Redis&trade; Pods (feature disabled by default). In case the master crashes, a new Redis&trade; 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).
### 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&trade; 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&trade; 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&trade; 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&trade; 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`.
### To 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&trade; StatefulSet before upgrading:
```bash
kubectl delete statefulsets.apps --cascade=false my-release-redis-master
```
And edit the Redis&trade; 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"}]'
```

{{- end }}
To connect to your Redis&trade; server:
1. Run a Redis&trade; pod that you can use as a client:
kubectl run --namespace {{ .Release.Namespace }} redis-client --restart='Never' {{ if .Values.auth.enabled }} --env REDISCLI_AUTH=$REDIS_PASSWORD {{ end }} --image {{ template "redis.image" . }} --command -- sleep infinity
{{- if .Values.tls.enabled }}
Copy your TLS certificates to the pod:
kubectl cp --namespace {{ .Release.Namespace }} /path/to/client.cert redis-client:/tmp/client.cert
kubectl cp --namespace {{ .Release.Namespace }} /path/to/client.key redis-client:/tmp/client.key
kubectl cp --namespace {{ .Release.Namespace }} /path/to/CA.cert redis-client:/tmp/CA.cert
{{- end }}
Use the following command to attach to the pod:
kubectl exec --tty -i redis-client \
{{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}--labels="{{ template "common.names.fullname" . }}-client=true" \{{- end }}
--namespace {{ .Release.Namespace }} -- bash
2. Connect using the Redis&trade; CLI:
{{- if eq .Values.architecture "replication" }}
{{- if .Values.sentinel.enabled }}
{{ if .Values.auth.enabled }}REDISCLI_AUTH="$REDIS_PASSWORD" {{ end }}redis-cli -h {{ template "common.names.fullname" . }} -p {{ .Values.sentinel.service.port }}{{ if .Values.tls.enabled }} --tls --cert /tmp/client.cert --key /tmp/client.key --cacert /tmp/CA.cert{{ end }} # Read only operations
{{ if .Values.auth.enabled }}REDISCLI_AUTH="$REDIS_PASSWORD" {{ end }}redis-cli -h {{ template "common.names.fullname" . }} -p {{ .Values.sentinel.service.sentinelPort }}{{ if .Values.tls.enabled }} --tls --cert /tmp/client.cert --key /tmp/client.key --cacert /tmp/CA.cert{{ end }} # Sentinel access
{{- else }}
{{ if .Values.auth.enabled }}REDISCLI_AUTH="$REDIS_PASSWORD" {{ end }}redis-cli -h {{ printf "%s-master" (include "common.names.fullname" .) }}{{ if .Values.tls.enabled }} --tls --cert /tmp/client.cert --key /tmp/client.key --cacert /tmp/CA.cert{{ end }}
{{ if .Values.auth.enabled }}REDISCLI_AUTH="$REDIS_PASSWORD" {{ end }}redis-cli -h {{ printf "%s-replicas" (include "common.names.fullname" .) }}{{ if .Values.tls.enabled }} --tls --cert /tmp/client.cert --key /tmp/client.key --cacert /tmp/CA.cert{{ end }}
{{- end }}
{{- else }}
{{ if .Values.auth.enabled }}REDISCLI_AUTH="$REDIS_PASSWORD" {{ end }}redis-cli -h {{ template "common.names.fullname" . }}-master{{ if .Values.tls.enabled }} --tls --cert /tmp/client.cert --key /tmp/client.key --cacert /tmp/CA.cert{{ end }}
{{- end }}
{{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
Note: Since NetworkPolicy is enabled, only pods with label {{ template "common.names.fullname" . }}-client=true" will be able to connect to redis.
{{- else }}
To connect to your database from outside the cluster execute the following commands:
{{- if and (eq .Values.architecture "replication") .Values.sentinel.enabled }}
{{- if contains "NodePort" .Values.sentinel.service.type }}
export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
