Status:

• implemented separate docker-compose.yml and .env file for cicd which compose together
  • essentials/advanced training doesn't have to change anything
• package pipeline : success
• product pipeline : success
• product pipeline (diamond with liba) : failure due to git conflict and then file-exists conflicts, needs fixing.
• promotion pipeline : won't start, no event in logs, asking jenkins/gitbucket for help
  • worst-case scenario workaround is that the scheduled (or manually triggered) scan of develop will detect the changes and build
  • we can implement that the promotion pipeline will run under that condition

To execute, do the following

    $ docker-compose --env-file .cicd.env -f docker-compose-cicd.yml  \
          -f docker-compose.yml up -d
    $ docker exec -it conan-training-cicd bash 

The nice part is that the containers and network all come up with -cicd suffix, making them completely independent containers from the ones used in essentials. We won't overwrite your data or break anyting.

At the same time, we get the benefit that the common layers will be shared, so storage is great (thanks docker).
