Switching between Discourse release channels / versions

In theory it should never be needed. Launcher will automatically detect an out-of-date copy, and do the git pull itself:

github.com/discourse/discourse_docker

launcher

ed9f680b0


      
          if [ $LOCAL = $REMOTE ]; then
            echo "Launcher is up-to-date"
          
          elif [ $LOCAL = $BASE ]; then
            echo "Updating Launcher..."
            git pull || (echo 'failed to update' && exit 1)
          
            echo "Launcher updated, restarting..."
            exec "$0" "${SAVED_ARGV[@]}"
          
          elif [ $REMOTE = $BASE ]; then
            echo "Your version of Launcher is ahead of origin"
          
          else
            echo "Launcher has diverged source, this is only expected in Dev mode"
          fi
