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:6.6.1 (1)
    1 couchbaseclusters.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:6.6.2 (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.
