Steps

Project Specific

1. Best-Practice: Have a separate docker folder in a suitable location within the project's directory structure.

   1. For VinePerf it is: tools/docker

2. Best-Practice: Within this docker folder, have a dedicate folder for each and every container that you plan to publish. 
   1. In VinePerf for Prox container, the path is: tools/docker/test-containers/trafficgen-pods/prox
3. In each container folder, ensure you have:
   1. Dockerfile, that is well tested.
   2. Source files that are referred in the Dockerfile, which is present in this folder' with ADD/COPY commands

Releng Specific

1. Download releng repo in order to submit a patch. git clone https://gerrit.opnfv.org/gerrit/releng

3. Open and Edit this file: https://github.com/opnfv/releng/blob/master/jjb/releng/opnfv-docker.yaml
   1. Setup receiver under existing receivers. See Change-1 below.
