Off-topic: does capsul do tagged releases? That'd be handy as the plugins/docker plugin has a auto_tag: true which generates the image tag based on the git tag. That is probably One For Later ™️

The last one was a year ago, I think, probably worth asking Cyberia if they'd be down for that?

Even more off-topic: can auto_tag: true work off the branch name? I'd love a way to be able to publish different images from different branches without hardcoding the branch name.

auto_tag doesn't, but I think it's possible with interpolating e.g. ${DRONE_COMMIT_BRANCH}, see 982556a

Feel free to ignore but I usually add --no-cache to save space and newline + sort things so it is easier to have a visual overview of dependencies and alphabetic ordering to know where to slot things in. Can be useful if you end up adding a lot of dependencies and then need to remove them over time as the software changes.

Optional: var = os.environ.get(f"{var_name}_FILE") also works as it defaults to None if missing.

Maybe postgres:9.6-alpine as it is smaller? https://hub.docker.com/_/postgres?tab=description&page=1&ordering=last_updated
