k8s-redis-sentinel

Contains k8s config files to start a Redis Sentinel service in kubernetes.

All steps and files are nearly identical to the ones found in this tutorial

Getting Started

Prerequisites

• kubectl is installed and configured properly for your needs.

1. Create a new namespace called "redis"

kubectl create namespace redis

2. Create the redis ConfigMap

kubectl apply -f redis-config.yaml

3.Create the redis ACL ConfigMap

kubectl apply -f redis-acl.yaml

4. Create the redis StatefulSet

kubectl apply -f redis.yaml

5. Create the sentinel StatefulSet

kubectl apply -f sentinel.yaml

6. Start the services

kubectl apply -f redis-service.yaml
kubectl apply -f sentinel-service.yaml

You should now see the pods running by running the following:

kubectl -n redis get all
