Replicated Redis setup for Kubernetes (GKE), with persistent disks and autoscaling

A replicated Redis setup running in GKE with GCE persistent storage and autoscaling, implemented with StatefulSet's.

First, create a namespace for our replicaset.

• kubectl create namespace redis-rs

Then create a persistent volume class:

• kubectl apply -f 01-hdd.yaml

Then create the first master and sentinel:

• kubectl apply -f 02-redis-master.yaml

Wait for master pod to be ready...

Then create the services for redis and sentinel:

• kubectl apply -f 03-redis-service.yaml
• kubectl apply -f 04-redis-sentinel-service.yaml

Then, first create a statefulset for redis...

• kubectl apply -f 05-redis-statefulset.yaml

...and then another one for redis sentinel:

• kubectl apply -f 06-redis-sentinel-statefulset.yaml

Lastly, create the autoscaler:

• kubectl apply -f 07-autoscaler.yaml

Scale up our replication:

• kubectl scale statefulset --namespace=redis-rs redis --replicas=3
• kubectl scale statefulset --namespace=redis-rs redis-sentinel --replicas=3

Delete the master pod:

• kubectl delete pods --namespace=redis-common redis-master
