Containers don't have ports

Question

I have some weird issue. All of my 8 containers are running and they are up, but non of them are showing ports (they are blank) on docker ps -a .

The weirdest thing is that all of those containers have been running normally last night showing ports on all of them. Also, I can enter each of those containers without any problems using docker exec -it <container_id> /bin/bash .

I have restarted my server and ports are still not showing up.

EDIT: I have used this https://pastebin.com/qZdQCjw1 docker-compose for init installation of all those apps in docker-compose file. After that I didn't change anything. This is a long shot, but could it be that I have installed docker-swarm and uninstalled it 1 min after installation that docker swarm change something, so I can't see ports for my containers?

Answer 1

I figure it out. I have tried to set specifically bridge network and assign it to all containers in docker-compose file. I have played with docker swarm for a minute and when I removed everything related to docker swarm, it still had overlay network, which is the reason why I missed ports. I had to manually set bridge and assign it to all services in docker-compose file and now it works like a charm.
