Here is a list of problems related to docker that we have already encountered. This list is maintained to make the debugging of unreasonable bugs easier ;)
- if you run out of storage bad thing happen, remember to plan enough storage
- be sure not to backup mounted docker images or images lying around in /var/lib/docker
- avoid loopback device mapper if possible (other setups are much better, see discussion in the technology discussions wiki page
- [Zombie Reaping problem] (https://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/) Solution: See the post
- [AUFS kernel deadlock bug] (https://github.com/docker/docker/issues/18180) Solution: Change the storage driver to either OverlayFS (faster) or DeviceMapper (slower). But the patch has been added to AUFS and should be available in the kernel soon. Side effect of this issue is that you will not be able to remove,stop or kill the container. Except the manually deleting its files.
