My AWS ec2 instance ran out of disk space (it has 16GB). I ran
rm -rf /var/lib/docker/overlay2 and
journalctl --vacuum-time=10d to free up space, and now
df says I have 7GB of free space. after rebooting the instance I get
Connection refused when trying to connect to the page.
sudo ./launcher rebuild app but it fails saying there less than 5GB of disk space.
