Absolutely possible if you keep the network setup simple. However, I run different sets of containers as different users, some of which also use services from the host itself (such as a PostgreSQL instance), and things quickly become more complex in these situations. The examples on the github helped me a lot to realise everything I wanted.

If you have caddy as a reverse proxy inside podman user namespace separated networks, they don't take the upstream client IP address and instead you get local IP addresses assigned to logs. Socket activation is kinda required if you want to get the client's real IP address in your logs.
