Yes, very disappointing, thanks for the answer.

Hi @blackjid,

Did this really work for you?

We would really need some way to get the env vars or outputs working in the container.images
This is required to do unit tests in a container which name is based on the project name, whatever the fork with no code change. I used the strategy below to add slugs for this.

With the following for building an image to use for tests, I get this error at “Initialize containers”:

Error: Docker login for '' failed with exit code 1
