I'm having a bit of a meltdown over here! I've been using Portainer to manage my Docker containers, but I'm not super familiar with command-line operations. I tried to create a stack for Gluetun in Portainer. Unfortunately, I messed up and set my container's IPv4 address to the same one as my laptop that's running the server. Now, my server can't connect to the internet, and I can't access SSH or Portainer anymore. Is there any way to fix this mess without deleting my other containers? I've tried changing the IP from my router settings and stopping the containers, but I'm not sure if I did it correctly. Any suggestions would be greatly appreciated!

First off, avoid setting static IP addresses for your containers—they can mess things up if you duplicate them, especially with your host IP. Instead, consider using Docker's host networking if you need the container to have the same IP as the host. It simplifies things a lot!
Yeah, I think the OP learned that the hard way!
To get back in control, start by checking all your Docker containers with `docker ps`. Once you have the list, you can stop them with `docker stop `. After that, run `docker network prune` to clean up your networks. Then, restart your containers and see if that does the trick!
Thanks a ton! This is just the info I needed! I stopped all my containers already, but I didn't know about the network prune thing—fingers crossed my next attempt at this works out!
Exactly! Host networking can be a lifesaver for certain configurations. Just remember that using it means your container will share the network stack of the host.
