    How-to upgrade Couchbase Server to a newer version.

    Given the existing configuration:

    yaml
    apiVersion: couchbase.com/v2 kind: CouchbaseCluster spec: image: couchbase/server:6.6.4 (1)
    1 couchbaseclusters.spec.image can be modified to any valid Couchbase Server image, in this example we want to upgrade the version only.
    yaml
    apiVersion: couchbase.com/v2 kind: CouchbaseCluster spec: image: couchbase/server:7.1.3 (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.
