Using a Postgres database

ONAP already has a Helm-based mechanism for deploying instances of Postgres and setting up credentials for client access.  We use this mechanism to create the DCAE postgres database already.   The drawback to this approach is that it creates a separate instance of Postgres each time it is used.  There has been work on setting up shared instances of databases in ONAP, but so far Postgres has not been included in those efforts. 

As we move DCAE service component deployment to Helm, we should make use of the ONAP project-wide Helm mechanisms.  If DCAE has certain special requirements, we should work to enhance the project-wide mechanisms.
