Description

I have a docker container as an Arch-based Linux distro. Usually I create the container and I push it by the build-push-action but when I create and push the container by this action, when I pull the image and run the container, the filesystem root has the following permissions:

drwxr-xr-x root root  26 B Wed Jun  5 10:27:55 2024  .
drwxr-xr-x root root  26 B Wed Jun  5 10:27:55 2024  ..

Look at etc and usr permissions. It creates several issues (like the /etc/sudoers.d being not working if it is world writable`).

When I build the same container locally and I push it by:

git clone https://github.com/Athena-OS/athena-rdp-docker.git
cd athena-rdp-docker
docker buildx build --tag 'athena-rdp:latest' .

docker login
docker push athenaos/rdp:latest

and then I run it by docker run, the permissions are set correctly.

So I have the described issue only when I use docker action. The GitHub workflow I use for it is:

name: Scheduled Publish

on:
  schedule:
    - cron: '22 4 * * 0'
  workflow_dispatch:

jobs:
  docker-publish:
    runs-on: ubuntu-latest
    steps:
      -
        name: Set up QEMU
        uses: docker/setup-qemu-action@v3
      -
        name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3
      - 
        name: Log to Docker Hub
        uses: docker/login-action@v3
        with:
          username: ${{ secrets.DOCKER_HUB_USER }}
          password: ${{ secrets.DOCKER_HUB_TOKEN }}

      -
        name: Build and push
        uses: docker/build-push-action@v5
        with:
          push: true
          tags: athenaos/rdp:latest

Instructions to run the container are on README of the https://github.com/Athena-OS/athena-rdp-docker repository.

Expected behaviour

/etc and /usr directories and some their subdir should have the right permissions, for example:

drwxr-xr-x root root 3.4 KB Wed Jun  5 10:33:25 2024  etc
drwxr-xr-x root root 162 B  Wed Jun  5 10:33:25 2024  usr

Actual behaviour

The filesystem root has the following permissions:

drwxrwxrwx root root 140 B Wed Jun  5 10:27:58 2024  etc
drwxrwxrwx root root  10 B Wed Jun  5 10:05:00 2024  usr
