Verify the Neo4j cluster formation

You check the pods and services to verify that the servers have managed to form a cluster.

  1. Check that the pods are READY.

    Typically, it takes a minute or two after the pods are running. They become READY after they form a cluster. You can watch pod status changes by adding the -w option to the kubectl command (kubectl get pods -w).

    kubectl get pods
    server-1-0   1/1     Running   0          147m
    server-2-0   1/1     Running   0          147m
    server-3-0   1/1     Running   0          147m
  2. You can also check the logs of the pods, for example:

    kubectl exec server-2-0 -- tail /logs/neo4j.log

  3. Check that the services look good:

    kubectl get services
