Docker Plugin randomly stops working

Hi everyone, we have a hard time getting our “Docker Cloud” setup (using the Docker Plugin) stable.

Our Cloud Host is running Podman (v 4.1.1) in rootless mode on RHEL9:

$ sudo cat /etc/systemd/system/podman.service.d/override.conf
ExecStart=/usr/bin/podman $LOGGING system service tcp: --time 0

We then connected our Jenkins master to it:

This works fine once. But in a subsequent run, Jenkins fails to connect to the Docker agent (via SSH) and after that, it doesn’t even send any request to the Podman socket anymore.

Versions in use:

Has anyone experience with using the Docker Plugin together with Podman or is there any idea how to debug that issue?

Thank you in advance!

BR, Chris
