Docker Instance Sign-in

I have several ignition gateways running on the same linux machine in their own docker containers. Everything is working well and I can connect to the different ports of the same IP address and connect to each individual gateway. The only oddity is that when I sign into the gateway in one instance then the user in another instance automatically gets logged out. It's not a massive deal but I'm confused about why ignition gateways running in their own container are interfering with each other.

Anybody got any suggestions?

Same hostname, same cookie, unfortunately.

You can make unique hostnames in /etc/hosts that all point at if you don't want to stand up any special DNS tools.

In one of the Docker training presentations, I remember @kcollins1 had a domain that would just resolve every name you threw at it as for convenience. I can't find it right now.

It may be the one he mentions in the post I linked,

It was the other one earlier in that thread: * :stuck_out_tongue:

I've found more and more systems offering native local resolution of *.localhost names, so that might be an option too, albeit possibly less universal.

Thanks Kevin - really was that simple huh??? I've been staring at the docker_compose.yml file for ages hahahaha
