When I was starting a Docker, it threw an error (invalid mount path/mount path must be absolute). After this, the docker disappeared from my list entirely. I had set the docker to listen on port 8090. I tried to reinstall the container but it told me the port was already bound, and so it was.

root@Sophos:~# lsof -i :8090
COMMAND     PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
docker-pr 12966 root    4u  IPv4  42252      0t0  TCP *:8090 (LISTEN)
docker-pr 12974 root    4u  IPv6  30308      0t0  TCP *:8090 (LISTEN)
root@Sophos:~# 

 

I then turned the docker service off/on, no change. I then rebooted, no change.

 

I think my old docker container is still lurking somewhere, just not in my docker list. Can anyone help me find and/or nuke it?

 

 

Possible necro post but in case anyone comes here searching. I had the same issue. I had created a custom br network so that internal dns worked and ran most containers from that. I needed to delete the network and recreate to fix the issue. There may be another way round but this is the one I found.
