How to use artifacts in build-push-action?

[KEGustafsson]

I tried to figuring out how to use artifacts in build-push-action, but didn't find the info?

I can upload and download artifacts in GH action. I can see that artifacts are in correct folder, but after starting docker/build-push-action@v2 action and doing ADD "folder" in docker build Dockerfile, folder is not containing just downloaded artifacts.

It seems that docker buildx build is loading git source, but not the one I have checked out.
How this should be done?

@KEGustafsson If you could post a repro (workflow + simple dockerfile + logs) that would help to understand the issue. Thanks.

@crazy-max Here is one example what I'm trying to do
https://gist.github.com/KEGustafsson/d57419e6f82f9fda98f37f6d7d0e04df

So, script download artifact to temp and then run build-push. Dockerfile ADD import folder to docker, but content is missing. Just downloaded artifact is not there.

Replacing GH action build-push to run cmd (below) works fine and temp file content is available to docker build.

     - name: Run Buildx docker and push
        run: |
          docker buildx build \
            --platform linux/amd64,linux/arm64,linux/arm/v7 \
            -t "latest" \
            -f ./docker/Dockerfile \
            --push .

Looks like you're using the Git context. As explained in the README:

Be careful because any file mutation in the steps that precede the build step
will be ignored, including processing of the .dockerignore file since
the context is based on the Git reference. However, you can use the
Path context using the context input alongside
the actions/checkout action to remove
this restriction.

So use the Path context instead:

      - name: Build and push
        uses: docker/build-push-action@v2
        with:
          context: .
          file: ./docker/Dockerfile
          platforms: linux/amd64,linux/arm/v7,linux/arm64
          push: true
          images: <user>/<repo>
          tags: latest

Also this input doesn't exist:

          images: <user>/<repo>

Thanks! Working perfectly!

Also this input doesn't exist:

          images: <user>/<repo>
