Note 1 : This topology use a Postgresql database for Evaluation or Demonstration usage which is not supported for a production environment. You need to adjust this Yaml to rely on an external database for a production topology.

Note 2 : To simplify this article we don't use Persistence Volume that means that if the dbserver pods restart the data are lost. To enable data persistence you should change the configuration by these following values

  persistence
    enabled: true
    storageClassName: '<A Valid Storage Classname>'
    useDynamicProvisioning: true

Step 5 ... Wait for installation 

Wait a couple of minutes to have the images downloaded and the instances created.

The container is ready when the deployments are in Dark blue color:
