scaling containers/pods

[tcurdt]

Let's say I want to adjust the amount of (backend) container instances on a single node.
There is no way with podman to let me easily adjust that, is there?
It seems the pod command does not have "scale" or similar.

The closest thing I can think of is using socket activation of containers togehter with ReusePort=true and quadlet templates.

I wrote an example where I can scale up to 2 by running

systemctl --user start [email protected]
systemctl --user start [email protected]

"1" and "2" are just a text strings in the example. The socket unit [email protected] activates [email protected] and [email protected] activates [email protected] . When a client connects to the port, the linux kernel will distribute the incoming connection to the socket in one the two services.
