Deploy Replica Set in Kubernetes Cluster

Tasks

• Create a ReplicaSet using the nginx image with the latest tag (specify as nginx:latest) and name it nginx-replicaset.

• Apply labels: app as nginx_app, type as front-end.

• Name the container nginx-container. Ensure the replica count is 4.

Steps

1. Create a manifest file name it as replicaset.yaml.

    apiVersion: apps/v1
    kind: ReplicaSet
    metadata:
      name: nginx-replicaset
    spec:
      replicas: 4
      selector:
        matchLabels:
          app: nginx_app
          type: front-end
      template:
        metadata:
          labels:
            app: nginx_app
            type: front-end
        spec:
          containers:
          - name: nginx-container
            image: nginx:latest
   

   

2. Now apply the configuration in k8s cluster.

    kubectl apply -f replicaset.yaml
   

   

3. Get replicaset

    kubectl get replicaset
   

   

4. Check the description of this replicaset.

    kubectl describe replicaset nginx-replicaset
