[BUG] Local ISO generation with the container image does not produce any files

[xynydev]

Describe the bug When running the container provided by this project to try to build a custom ISO, no files are created into the bind-mounted volume, and no ISO is available after the generation process is complete.

To Reproduce

1. Open the terminal (optionally, navigate to an empty directory like ~/iso/)
2. Run the command provided in the README: docker run --rm --privileged --volume .:/github/workspace/build ghcr.io/jasonn3/build-container-installer:latest VERSION=38 IMAGE_NAME=base IMAGE_TAG=38 VARIANT=Server
   • I had to use sudo because of how my host is set up.
   • Here's the log: https://paste.centos.org/view/0c4da6c0
3. Wait for command to complete
4. Check directory with ls, no ISO file is found.

Additional things I tried

• Building an ISO of my own custom image with the following commands:
  • Setup:

    IMAGE_REPO=ghcr.io/xynydev
    IMAGE_NAME=linuxyz
    IMAGE_TAG=latest
    IMAGE_VARIANT=Silverblue
    mkdir ./iso

  • Build with docker:

    sudo docker run --rm --privileged --volume ./iso:/github/workspace \
    -e IMAGE_REPO="$IMAGE_REPO" -e IMAGE_NAME="$IMAGE_NAME" -e IMAGE_TAG="$IMAGE_TAG" -e VARIANT="$IMAGE_VARIANT" \
    ghcr.io/jasonn3/build-container-installer:latest

  • Build with podman:

    sudo podman run --rm --privileged --volume ./iso:/github/workspace --security-opt label=disable --pull=newer \
    -e IMAGE_REPO="$IMAGE_REPO" -e IMAGE_NAME="$IMAGE_NAME" -e IMAGE_TAG="$IMAGE_TAG" -e VARIANT="$IMAGE_VARIANT" \
    ghcr.io/jasonn3/build-container-installer:latest

  • No files were created in the ./iso/ directory with either of these commands.
• I also looked at the action.yml to see if the mount path (/github/workspace/) had changed from when the documentation was written, but I didn't find any indication of such a thing.

Expected behavior When running the container with the bind mount, it should output the ISO file into the mounted host directory.

Desktop (please complete the following information):

• OS: Fedora Silverblue (custom image)
• Version: 39

Additional context

• Docker version 24.0.5, build %{shortcommit_cli} (from moby-engine)
• podman version 4.9.4 (pre-installed)
• Custom image repository: https://github.com/xynydev/linuxyz

Sorry, forgot to update the examples in the readme. The volume needs to be --volume ./iso:/build-container-installer/build. You can also override the location that the ISO will be written by using ISO_NAME. Just remember that any path specified is relative to /build-container-installer unless you specify an absolute path and then it's based on inside the container runtime.

I see, I see. Thanks! That worked splendid. I'll keep this issue up so y'all don't forget to change this in the docs.
