So I am absolutely losing my marbles here. Ubuntu 18.04.2 I have Docker + Portainer installed via a local container. I can access the portainer UI via https://ip-address:9000

However, I also installed napp-it for ZFS management. I am supposed to connect to it on http://ip-address:81, but the connection just times out.

Firewall disabled for testing and still nothing.

root@daviserver:~# ufw status
Status: inactive

You can see the service running on the last line here

root@daviserver:~# lsof -i -P -n | grep LISTEN

mini-http 4975         napp-it    4u  IPv6  46582      0t0  TCP *:81 (LISTEN)

I also installed Cockpit, can see it running on port 9090 and I cannot connect to it either. I am not even sure where else to look at this point.

  • Your question is missing the information which services are running in which containers, and you have to tell docker which ports needs to be mapped to which container ports when you start the container. So my first guess would be that you forgot that. – dirkt Jun 15 at 16:59
  • I shut down all my containers and the issue still persist. From what I understand the docker daemon binds to 0.0.0.0, but it shouldn't bind on every port right? – nitrobass24 Jun 15 at 17:37
  • When you run docker, are you using the -p <host port>:<container port> argument to map the connection into the container's ports? – Jeff H. Jun 15 at 22:09
  • Yes I was mapping ports that way. At this point I have uninstalled docker and still have issues. Just going to re-install the OS and start over. – nitrobass24 Jun 16 at 4:25
