Deploy operator


helm repo add 21h
helm repo update
helm install redis-operator 21h/redis-operator -n operators

Namespace-scoped installation

kubectl -n operators -f deploy/service_account.yaml
kubectl -n operators -f deploy/role.yaml
kubectl -n operators -f deploy/role_binding.yaml
kubectl -n operators -f deploy/operator.yaml

Edit operator.yaml to set WATCH_NAMESPACE, may be you want set it to namespace of pod:

        fieldPath: metadata.namespace

Cluster-scoped installation

kubectl -f deploy/clusterrole.yaml
kubectl -f deploy/clusterrole_binding.yaml
kubectl -n operators -f deploy/service_account.yaml
kubectl -n operators -f deploy/operator.yaml

Edit clusterrole_binding.yaml, set namespace for service account.

Your first Redis deployment

This resource can help you run your first Redis instance

kind: Redis
  name: my-redis
  useHAProxy: true
  haproxyReplicas: 1
  sentinelReplicas: 3
  redisReplicas: 3
  quorum: 2
  haproxyTimeoutServer: 30
  haproxyTimeoutClient: 30
  haproxyBackendCheckInterval: 1
  # set size if you want make persistent volume
  persistentVolumeSize: 1Gi
  persistentVolumeClass: "gluster"
  persistentVolumePurge: true
    maxUnavailable: 1
    minAvailable: 2

Remember rule: pdbSentinel.minAvailable > (sentinelReplicas / 2) > pdbSentinel.maxUnavailable. This made to save quorum.

Open file pkg/apis/blindage/v1alpha1/redis_types.go to know more about options.
