softputer/kubernetes-redis-cluster-replicaset repository overview

⁠Kubernetes Redis Cluster By ReplicaSet

This repo is inspired by Kelsey Hightower's kubernetes-redis-cluster⁠. But I have remove the usage of google cloud platform disk which makes it more flexible to deploy. And I have include redis.conf in the new image by the Dockerfile in the repo.

⁠Create Redis Nodes

kubectl create -f replicasets

⁠Create Redis Services

kubectl create -f services

⁠Connect Nodes

kubectl run -i --tty redis-trib --image=softputer/redis-trib \
  --restart=Never /bin/bash

./redis-trib.rb create --replicas 1 \
  10.131.242.1:6379 \
  10.131.242.2:6379 \
  10.131.242.3:6379 \
  10.131.242.4:6379 \
  10.131.242.5:6379 \
  10.131.242.6:6379

The IP above can be either pod ip or service ip. After executing the command successfully, you will get a reds cluster with 3 masters and 3 slaves.

⁠Add a new node

kubectl create -f replicaset/redis-7.yaml

kubectl create -f services/redis-7.yaml
