From 50aafc5ef50a1280c9e85d12be3d24104258ae95 Mon Sep 17 00:00:00 2001 From: Dominic Lunanuova Date: Fri, 30 Mar 2018 02:29:23 +0000 Subject: Initial chart for dmaap - 2nd attempt This should conform to new OOM standard helm structure. It starts a directory called dmaap which will hold all dmaap components. But for now it only has buscontroller. Once we get this working, we can add message-router. (see DMAAP-386) Patch 2 gets private postgresql working. I'd prefer to integreate with common postgresql from Tony in a future commit to avoid any immediate delivery timing dependency. Patch 3 corrects some port mapping from service to pod.
