Kuberneter Redis Database Assignment Operator

Usage

Suggested usage is to use Helm to install this operator:

helm repo add WyriHaximusNet https://helm.wyrihaximus.net/
helm repo update
helm upgrade redis-db-assignment-operator WyriHaximusNet/redis-db-assignment-operator --install --wait --atomic --namespace=redis

After the Helm install following definition will create a redis-database resource on your cluster. The operator picks it up and finds a redis database that isn't in use according to the operators internal state.

apiVersion: wyrihaximus.net/v1
kind: RedisDatabase
metadata:
  name: example
spec:
  secret:
    name: example-redis-database
  service:
    read: redis://redis-follower.redis.svc.cluster.local:6379/
    write: redis://redis-leader.redis.svc.cluster.local:6379/

The resulting secret looks like this:

apiVersion: v1
kind: Secret
type: Opaque
metadata:
  name: example-redis-database
  namespace: default
data:
  DATABASE: BASE64_ENCODED
  READ: BASE64_ENCODED
  WRITE: BASE64_ENCODED
