Description
Docker Compose uses environment variables for variable substitution in Compose files. I leverage this heavily in GitLab CI pipelines to "render" Compose files (using docker-compose config). CI variables are passed to jobs as environment variables, and the Compose files in my repositories use these in various ways.
Is it possible to introduce an option to docker-app render and docker-app deploy to use environment variables as a source for settings?
Steps to reproduce the issue:
- Create a Docker App with a variable such as
$PWD. - If necessary, ensure the variable is defined in the environment.
- Render the app with
docker-app render.
Describe the results you received:
The rendered app does not contain the value of $PWD from the environment.
Describe the results you expected:
I would like an option to tell Docker App to use environment variables as settings.
Additional information you deem important (e.g. issue happens only occasionally):
