Redis Installation Guide for Kubernetes

This guide demonstrates how to install Redis in a Kubernetes environment.

1. Prerequisites

Ensure the following before proceeding:

• A running Kubernetes cluster with kubectl configured.
• Basic knowledge of YAML configuration.
• Permissions to deploy resources in the cluster.

2. Create Redis Deployment and Service YAML Files

Create two YAML files: one for the Redis Deployment and another for the Service.

redis-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
      - name: redis
        image: redis:6.2
        ports:
        - containerPort: 6379
    

redis-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: redis
spec:
  ports:
  - port: 6379
    targetPort: 6379
  selector:
    app: redis
    

3. Apply Redis YAML Files to the Cluster

Use the following commands to deploy Redis in your Kubernetes cluster:

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

This will create a Redis Pod and expose it using a Kubernetes Service.

4. Verify Installation

Check the status of your Redis Deployment and Service:

kubectl get pods
kubectl get services
    

To access Redis, use the Redis CLI tool or connect to the Pod directly:

kubectl exec -it <redis-pod-name> -- redis-cli
PING
    

If Redis is running properly, you should receive a PONG response.
