Portworx not working on Fedora CoreOS 34 and RKE

I’m trying to install Portworx Essentials on my RKE Cluster with 3 Fedora CoreOS 34 Nodes. I tried the installation with the Operator, DaemonSet and the Rancher Catalog App.

I always get these this error:
time=“2021-08-29T20:59:30Z” level=error msg=“Could not talk to Docker/Containerd/CRI: Could not determine my container ID: Container not found - please ensure ‘/var/run/docker.sock’, ‘/run/containerd/containerd.sock’ or ‘/var/run/crio/crio.sock’ are mounted.”

The file /var/run/docker.sock is present on the host and systemctl status docker.socket shows that it’s running. /var/run is a symlink to /run on Fedora CoreOS so I also tried to change the hostPath to /run/docker.sock but the same error appears. SELinux is disabled.

Fedora CoreOS version: 34.20210808.3.0
RKE Version: 1.20.9
Docker version: 20.10.7

Does anyone have an idea? Thank you.

Same problem on OpenSUSE MicroOS. Not working with Kubic and K3s.
