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. + +### 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. + +- Number of slaves: +```diff +- cluster.slaveCount: 2 ++ cluster.slaveCount: 3 +``` + +- Enable NetworkPolicy: +```diff +- networkPolicy.enabled: false ++ networkPolicy.enabled: true +``` + +- Start a side-car prometheus exporter: +```diff +- metrics.enabled: false ++ metrics.enabled: true +``` + +### Cluster topologies + +#### Default: Master-Slave + +When installing the chart with `cluster.enabled=true`, it will deploy a Redis master StatefulSet (only one master node allowed) and a Redis slave StatefulSet. The slaves 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 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 master StatefulSet (only one master allowed) and a Redis slave StatefulSet. In this case, the pods will contain en 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 accesing 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 +``` +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 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 +``` + +### 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. + +### Host Kernel Settings +Redis 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 + - |- + install_packages procps + 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 stable/redis +``` + +## NetworkPolicy + +To enable network policy for Redis, 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. 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 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 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 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 stable/redis --set persistence.existingClaim= + ``` + + - Alternative (not recommended, do at your own risk): `helm delete --purge` does not remove the PVC assigned to the Redis Master StatefulSet. As a consequence, the following commands can be done to upgrade the release + + ``` + helm delete --purge + helm install stable/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 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 StatefulSet before upgrading: +```bash +$ kubectl delete statefulsets.apps --cascade=false my-release-redis-master +``` +And edit the Redis 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"}]' +``` + +## Notable changes + +### 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 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). + +### 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 Sentinel containers inside of the Redis Pods (feature disabled by default). In case the master crashes, a new Redis 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.
