How to show debug build log?

[seepine]

eg docker build -t xxx --debug -f Dockerfile .
I didn't find similar parameters in docker/build-push-action.

You can set the DEBUG: 1 env var in your workflow that would act the same as the --debug flag:

      -
        name: Build and push
        uses: docker/build-push-action@v6
        with:
          push: true
          tags: user/app:latest
        env:
          DEBUG: 1

If you want the BuildKit logs with debug enabled, see https://docs.docker.com/build/ci/github-actions/configure-builder/#buildkit-container-logs

env.DEBUG is valid, but I still can't see what's wrong. I can build successfully using docker buildx cli, but fail using actions self on the same computer.

Dockerfile

FROM oven/bun:alpine
WORKDIR /workspace
COPY package.json ./
RUN bun install --production
COPY ./ ./
RUN bun run build

Seems bun install exit with code 1 without any logs which sounds related to the bun command itself failing. I don't know what bun is but maybe you have a flag to enable debug or have more verbosity during install?
