This document highlights design considered for to Provision authenticated, authorized DMaaP topics on Message Router and feeds on Data Router .
...
- Authorized topic on MR, and to create and grant permission for Publishers and Subscribers.
- Feed on Data Router, with associated user authentication.
- Bus Controller API link : https://docs.onap.org/projects/onap-dmaap-buscontroller/en/latest/apis/api.html

Dmaap dbc-client docker Image (onap/dmaap/dbc-client:2.0.7)
This dbc-client image is utility (containing shell script) by making use of which we can initiate HTTP REST Request towards Dmaap Bus Controller app for creating dynamic Feeds, Topics.
...
- Existing design consist fo kubernetes Job Manifest which consist of onap/dmaap/dbc-client docker image for making http request toward dmaap-bc (Dmaap Bus Controller) pod.
- In DCAE Design-1 highlighted in below pic is considered where we need to create dmmap provisionning Init-Container which will be making use of same onap/dmaap/dbc-client docker image to make Http Rest Request towards dmap-db pod.
- Once the http request is made response will be written back to shared EmptyDir voulme.
- Second Init-container (Update Config) will be reading the response from share EmptyDir voulme and will merge it with application config.

Draw.io design-1 :
- Dmaap Provisioning init-container sends POST request to Dmaap Bus-Controller Pod for creation of Topics, Feeds.
- DCAE Merge init config container merges dcae application config and response received back from dmaap provisioning init-container.
