Does rootless podman works? Can someone help me with setup?

[frenkye]

Hi,

i tried to setup this for 3 scenarios:

1. docker root - works
2. docker rootless - works
3. podman rootles - do not work

I have issue with cadvisor not returning metrics about cpu, memory of running containers. I would appreciate, if anyone could give me some hint how to do it.

I know for long time there wasnt full support in 0.47.2, but this should be now in 0.49.1 available since support was added in 0.48.0

Client:       Podman Engine
Version:      4.9.3
API Version:  4.9.3
Go Version:   go1.21.6
Built:        Thu Jan  1 01:00:00 1970
OS/Arch:      linux/amd64

Last run command:

        RUN_IMAGE="podman run -d --restart always -p ${PORT}:8080 \
            -v /:/rootfs:ro \
            -v /etc/machine-id:/etc/machine-id:ro \
            -v /sys:/sys:ro \
            -v /dev/disk:/dev/disk:ro \
            -v /run/containerd/containerd.sock:/run/containerd/containerd.sock:rw \
            -v /run/user/${UID}/podman/podman.sock:/var/run/podman/podman.sock:ro \
            -v ${ROOTLESS_HOMEDIR}/.local/share/containers/:/var/lib/containers:ro \
            --name=${CONTAINER_NAME} \
            gcr.io/cadvisor/cadvisor:${CONTAINER_VERSION}"

I am also trying rootless and having no luck seeing container data.
Additionally i can add i am ensuring that the podman flag is set, ie. --podman="unix:///var/run/podman/podman.sock"
and that i do see ack in logging, eg.

I0319 02:23:08.886522       1 factory.go:221] Registration of the podman container factory successfully

In my environment it runs as Rootless:
