I am facing a similar issue with other docker-compose commands.

With docker-compose up, one could pass the --no-build option to skip the

build:
    context: .

but how should we do it for

docker-compose down or docker-compose stop or even docker-compose ps ??

They are all likely to fail without the --no-build option.

btw, did you find another way ?

[moaxcp]

I just ran into this again with so much panic. There are two solutions that I have found.

1. Add an empty directory where the sources would be located
2. Add the git url for the repo in an override file and use it

For 1 I haven't recently tried this but I remember it working.

For 2 I had to use the http urls not ssh.
