Checkout isn’t working

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

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

Ah, interesting; I didn’t know it was not yet supported in BuildKit. I opened a tracking issue for that; https://github.com/moby/buildkit/issues/1684

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