podman inspect returning empty Port bindings when running container inside a rootless podman container. about podman HOT 3 OPEN

check containers.conf inside the image, https://github.com/containers/image_build/blob/main/podman/containers.conf

As you can see the default netns mode is set to host so there are no ports. Normally you should get warning like this
Port mappings have been discarded as one of the Host, Container, Pod, and None network modes are in use.
Seems like this doesn't work when the netns is set in containers.conf though.

Thanks @Luap99.

We were trying to get OpenShift + Jenkins Agent Pods with Rootless Podman working to support CI builds that use testcontainers. Following the blog article https://www.redhat.com/sysadmin/podman-inside-container and trying to use Podman stable image.

If we cant use netns:host, I guess we can only run testcontainers in rootfull mode.

Well you can just run with --network bridge to overwrite the default but this might not work if you try to run in an unprivileged pod.
