Is anyone `pants publish`ing Docker images on GitLab CI? This requires Docker-in-Docker AFAIK, but the official

docker:X.Y.Z-cli

images are Alpine based which pants does not support. There are several threads on the topic here, but none with conclusive guidance for how to go about this. An example

gitlab-ci.yaml

would be super helpful, as would any general guidance.

Long story short I’m trying to deploy an Azure Function app via container. While zip-deploying PEXes has worked in the past, I’ve encountered some incompatibility with PEXes produced starting around Pants 2.20 (search for my previous thread on the topic).

Sorry for the trouble, seems like this has been a bit of a saga for you. Is https://pantsbuild.slack.com/archives/C046T6T9U/p1733484343664749 relevant? (Unfortunately I don’t know anything about Gitlab myself so cannot help with the specifics)

Definitely has been a saga 😅. Building our own Docker image or using our runners is an option, but it’d be great to avoid the extra complexity if possible. I’d love to figure out what, if anything, changed about the PEX formulation between 2.19 and 2.20 that caused our Functions to break, though I’m out of my depth there. I’m optimistic the flatter package of the

python_aws_lambda_function

target will resolve the issue. I initially got PEXes working in Azure Function App land by adding the following block between Python standard library imports and first+third party imports and I wonder if this kludge is also somehow implicated in the current issues I’m facing 🤷

Copy code

try:
    import __pex__  # type: ignore # noqa # pants: no-infer-dep
except ModuleNotFoundError:
    pass

Thanks for the help btw. I’ll keep this thread updated.

Promising early results… I used

python_aws_lambda_function

to package the test Function I linked in the other thread and it works! This could be it! The

handler

field is symbolic, but I can use

dependencies

to include all the Functions (must be in separate directories per Azure’s requirements 🙃)

I've had some success using

cruizba/ubuntu-dind:noble-27.1.1

as pretty much a drop in replacement for the regular alpine dind image

Thanks, I was looking around for such an image but had trouble digging it up. So far it looks like I can avoid needing dind using the

python_aws_lambda_function

target, but if it doesn’t pan out I’ll give it a a shot.

Is anyone pants publishing Docker images on GitLab CI?

Yes! But we are hosting our own runners so dind isn't an issue for us. If I'm misreading and the other pointers don't help let me know

I’m good to go. Huon’s suggestion allowed me to avoid the need for building pex-in-docker to deploy to Azure Functions 🎉
