Deploy a cassandra to the cluster

• Create a deployment yaml file

apiVersion: apps/v1
kind: Deployment
metadata:
  name: cassandra
  labels:
    app: cassandra
spec:
  replicas: 1
  selector:
    matchLabels:
      app: cassandra
  template:
    metadata:
      labels:
        app: cassandra
    spec:
      containers:
      - name: cassandra
        image: cassandra:4.1
        ports:
        - containerPort: 9042
        env:
        - name: CASSANDRA_CLUSTER_NAME
          value: "CassandraCluster"
        - name: MAX_HEAP_SIZE
          value: "512M"ply -
        - name: HEAP_NEWSIZE
          value: "100M"
        volumeMounts:
        - name: cassandra-data
          mountPath: /var/lib/cassandra
      volumes:
      - name: cassandra-data
        emptyDir: {}

• Deploy cassandra from a deployment yaml file kubectl apply -f cassandra.yaml After successfully executes the above command, check if cassandra pod is up and running.

kubectl get pods

neilwu@A8:~/apps/kubernates/deployment$ kubectl get pods
NAME                         READY   STATUS    RESTARTS   AGE
cassandra-6bfbff8548-qd8n7   1/1     Running   0          25m

Excellent !, your first cassandra pod is up and running.
