Bug in discourse launcher

This may be why it isn’t working properly then, I think that the launcher script expects you are running on Debian/Ubuntu. It seems like your stat error is from the BusyBox version of stat not recognizing the format flag here:

github.com/discourse/discourse_docker

launcher

main


      
          if [[ "$test" =~ "working" ]] ; then : ; else
            echo "Your Docker installation is not working correctly"
            echo
            echo "See: https://meta.discourse.org/t/docker-error-on-bootstrap/13657/18?u=sam"
            exit 1
          fi
          
          # 7. enough space for the bootstrap on docker folder
          folder=$("$docker_path" info --format '{{.DockerRootDir}}')
          safe_folder=${folder:-/var/lib/docker}
          check_disk() {
              local free
              free=$(( $(stat -f --format="%a*%S" "$safe_folder") ))
              (( free >= 5 * 1024**3 ))
          }
          
          if ! check_disk; then
            echo "You have less than 5GB of free space on the disk where $safe_folder is located. You will need more space to continue"
            df -h $safe_folder
            echo

The command is working fine on my Arch PC so presumably it’s okay on Ubuntu too.

I believed this may have been potentially related to a change I made recently but I maintained the logic from the previous version so it seems to just be a BusyBox thing.
