helm status my-release -n couchbase-cluster

If you want to delete your Chart, use this command

helm delete my-release -n couchbase-cluster

Using node selector

For example, you have 3 vms in node pools and you want to deploy graylog to node which labeled as cloud.google.com/gke-nodepool: couchbase-pool Set the following values in values.yaml

   nodeSelector: { cloud.google.com/gke-nodepool: couchbase-pool }

Using tolerations

For example, you have 6 vms in node pools and 3 nodes are tainted with NO_SCHEDULE couchbase=true Set the following values in values.yaml

  tolerations:
    - key: couchbase
      value: "true"
      operator: "Equal"
