Deploy Redis Cluster on top of OCP

Redis Cluster Integration for OpenShift Container Platform

The objetive for this repository is to deploy a Redis Cluster on top of Openshift Container Platform.

1. Create the redis-cluster namespace on your Cluster

    # oc new-project redis-cluster
   

2. Import the template from source

    # oc create -f https://raw.githubusercontent.com/makentenza/ocp-redis-cluster/master/kube/redis-cluster-ephimeral.yaml
   

3. Create the new application from the imported template

    # oc new-app redis-cluster-ephemeral
   

   --> Deploying template "openshift/redis-cluster-ephemeral" to project redis-cluster

      redis-cluster-ephemeral
      ---------
      Redis 3 Cluster Node Ephemeral
   
      Redis 3 Cluster Node Ephemeral
   

   --> Creating resources

      serviceaccount "redis" created
      imagestream "redis-cluster-node" created
      service "redis-cluster-service" created
      service "redis-cluster-node01" created
      service "redis-cluster-node02" created
      service "redis-cluster-node03" created
      buildconfig "redis-cluster" created
      deploymentconfig "redis-cluster-node01" created
      deploymentconfig "redis-cluster-node02" created
      deploymentconfig "redis-cluster-node03" created
   

   --> Success

4. Add the redis service account to anyuid Security Context Constraint so redis user could start processes inside de image

    # oc adm policy add-scc-to-user anyuid system:serviceaccount:redis-cluster:redis
   

Following these instructions a 3 Redis Cluster Node will automatically be created, properly shard Nodes so data is automatically sharded across multiple Redis nodes. In order to operate the Cluster (Adding Nodes, Removing Nodes, Resharding the Cluster) follow the Offical Documentation
