Upgrade a Couchbase Deployment

      +
      How-to upgrade Couchbase Server to a newer version.

      Given the existing configuration:

      apiVersion: couchbase.com/v2
      kind: CouchbaseCluster
      spec:
        image: couchbase/server:6.5.1 (1)
      1 spec.image can be modified to any valid Couchbase Server image, in this example we want to upgrade the version only.
      apiVersion: couchbase.com/v2
      kind: CouchbaseCluster
      spec:
        image: couchbase/server:6.6.0 (1)
      1 The modification will trigger the Operator to detect that existing pod specifications do not match the new pod specifications. This will perform a rolling upgrade of Couchbase Server.
