Bug in discourse launcher

Hello,

The installation claims I don’t have enough space, but I have

Earlier I have stat error :

So I think I need to install a special version of stat ?

Host is an Alpine

I think you may be looking in the wrong place for free space, do you see anything different with

df -h /var/lib/docker

if you don’t have enough space there, you can try ./launcher cleanup from /var/discourse to remove old images

Good idea if you can to share text, not screenshots, so these things can be searched on.

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.
