This k8s module is intended to simplify the creation and operation of a Redis Cluster deployment in Kubernetes.
These directions assume some familiarity with Redis Cluster.
When you create the resources in Kubernetes, it will create a 6-member (the minimum recommended size) Stateful Set cluster where the first,second,third member become master and other members are slaves.
To launch the cluster, have Kubernetes create all the resources in redis-cluster.yaml:
$ kubectl create -f redis-cluster.yaml
configmap/redis-cluster created
statefulset.apps/redis-cluster created
service/redis-cluster created
Wait a bit for the service to initialize.
Once all the pods are initialized, you can see that Pod "redis-cluster-0" "redis-cluster-1" "redis-cluster-2" became the cluster master with the other nodes as slaves.
$ kubectl exec -it redis-cluster-0 redis-cli cluster nodes
