Communication between podman containers without root - docker

Question

I am trying to deploy a web app with two podman containers. One is running gunicorn and the other runs a web server as a reverse proxy.
However, the communication between the containers is only successfull if I run them on the host with root. Is there a way around this?
Here is an example without root (which returns an empty IP Address):
$ podman run -dt --name test --rm -p 8000:8000 python:3.9 python -m http.server
$ podman container inspect test | grep IPAddress
"IPAddress": "",
With root, it is possible to do:
$ sudo podman run -dt --name test --rm -p 8000:8000 python:3.9 python -m http.server
$ sudo podman container inspect test | grep IPAddress
"IPAddress": "10.88.0.11",
"IPAddress": "10.88.0.11",
$ cat Dockerfile
FROM caddy:2
COPY Caddyfile /etc/caddy/Caddyfile
$ cat Caddyfile
:8001 {
reverse_proxy * 10.88.0.11:8000
}
$ sudo podman build . -t revproxy
$ sudo podman run -dt --rm -p 8001:8001 revproxy
and the proxy is working successfully on port 8001.

Answer 1

The two containers have to be in the same pod or the same network.
Using a pod, it is possible to do the following:
$ podman pod create -n test
$ podman run --rm --pod test python:3 python3 -m http.server
and in another shell:
$ podman run --rm --pod test python:3 curl localhost:8000
