Checkout isn’t working

[ThisIsQasim]

Behaviour

As per the docs, it should automatically checkout the repo before building the docker image. I am building an image with a build context of a subfolder and the working directory is empty.

Steps to reproduce this issue

1. Try to build an image with a context other than .
2. Build will fail citing missing directory

Expected behaviour

Repo should be cloned and build should succeed.

Actual behaviour

Repo is not cloned and build fails

As I can see you're using a path context context: elasticsearch so in your case you have to checkout before using this action.

If you want to rely on Git context to allow buildx to checkout the repository for you, remove the context input.

Can I change the context to a directory using git context?

Can I change the context to a directory using git context?

A way to define a subdir would be to use:

context: https://github.com/${github.context.repo.owner}/${github.context.repo.repo}#${github.context.ref}:my/subdir

But this is not yet supported. I will add a note in the README about this.

I think it's easier and cleaner to just clone in a separate step

Ah, interesting; I didn't know it was not yet supported in BuildKit. I opened a tracking issue for that; moby/buildkit#1684
