  1. 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.
  2. 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.
    1. Once the http request is made response will be written back to shared EmptyDir voulme.
    2. Second Init-container (Update Config) will be reading the response from share EmptyDir voulme and will merge it with application config.

Updated Design:

Draw.io design-1 :

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