Portainer Network Mode/Host Error

General
1

Hi all,

I am new to Docker and Portainer and I am having an issue with my Gluetun stack (Gluetun, NATMAP, Jackett, qBittorrent), I can get it setup and running but if I try to use the Recreate button inside Portainer to rebuild the container I get the following error message.

“Failed recreating container: Create container error: Error response from daemon: conflicting options: hostname and the network mode”

I am lost as to why I get this error as everything in the stack works correctly, the vpn connection and network pass-through all work, the only issue is recreating the container, note that I am creating the stack using Docker Compose, if I try to do it from inside Portainer it throws the above error message but the stack is still created correctly. I have tried removing the hostname from the compose file, and setting one specifically (vpn), I get the same result.

Anyone else had this issue, any advise?

Here is my compose file.

Which one?

If it is about recreating then you have a container which works, and the new container cannot be created.

Stack indicates you run Swarm stacks, but you also menation compose. Which one you use?

The error message says the hostname option and the network mode is conflicting, which is true, since you can’t set the hostname when when you use the network namespace of another container or the host network. Using another network namespace means you also use the hostname of the other container.

Since there is no hostname in your compose file, I have no idea what the problem is. If it is a Portainer bug, you can try a portainer forum
