Comment on Question about quadlets and kube play

Awesome, thanks!

In terms of architecture, which is preferred:

separate pod per “app” (e.g. NextCloud), but all one network
separate pod and network per app
everything in one pod

I’d like to have one gateway, Caddy, so my cert renewal and proxying are all in one place, and I’d like those proxy configs to look like http://<container>

I’d prefer my containers not be able to talk to each other unless I specifically allow it. The second option would get me that, but I think it would force me to expose ports for each app to the system.

TL; DR - Can I have a “Caddy” pod that can see exposed ports from other pods, but hide those ports from regular system users? If not, I’ll probably do the first option. I also want to be able to expose ports to the host on a per app basis if needed.

I ran a podman quadlet setup as a test some time ago. My setup was a little like this:

Create a pod if the app uses multiple containers

Create a seperate network for each app (either a single container or multiple containers grouped in a pod)

Add the reverse proxy container to all networks

I don’t expose any ports to the host unless necessary If you create a new network in podman you can access other containers and pods in the same network with their name like so container_name:port or pod_name:port. This functionality is disabled in the default network by default.

  Awesome, that’s exactly what I want! I guess I missed where pods could be part of multiple networks.
  
  I’m on podman 4.x, but I’m planning to upgrade the OS anyway soon, so it probably won’t be an issue.
  
  Thanks, you’re a stud!

I use one pod per app more or less. The reverse-proxy conf depends a bit on the specific app so that depends, but it will probably work for most by sharing a network and exposing the ports in the pods
