I have been searching for an answer for this for days and don't know the best place to ask for help, I must be missing something simple.
This problem is common to both my Fedora27 workstation and Ubuntu Server 16.04 LTS
I have installed Docker successfully and have some containers working but others cannot be accessed on 0.0.0.0: or localIP:
I have disabled firewall and flushed iptables, amongst others I am trying to get a minecraft server running on 25565, following this instruction:
To simply use the latest stable version, run
docker run -d -p 25565:25565 --name mc itzg/minecraft-serverwhere the standard server port, 25565, will be exposed on your host machine.
The container runs OK:
[benjbt@localhost ~]$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3240121d414e itzg/minecraft-server:latest "/start" 2 minutes ago Up 2 minutes (healthy) 0.0.0.0:25565->25565/tcp, 25575/tcp mc
8f1cf88207e7 portainer/portainer "/portainer" 9 minutes ago Up 9 minutes 0.0.0.0:9000->9000/tcp eager_northcutt
However, the port is not accessible:
can’t establish a connection to the server at 0.0.0.0:25565
Please help me understand what is blocking my port?
[benjbt@localhost ~]$ sudo iptables -L
