SystemD - DBus error: Failed to connect to bus: No such file or directory

[Jonas18175]

Hello,

i tried to setup several tests for different os - it worked great in beginning but now i get a systemd dbus error on following command:

set -o pipefail
systemctl list-unit-files | egrep "^(docker|podman).*.service" | egrep -v "^.*-auto-update" | awk -F' ' '{print $1}'

I use it to autodedect the service name for docker.

How can i fix the dbus deamon?

My molecule file:

Maybe this is roughly the same problem as #3108 ?

[Jonas18175]

Yes it is the same problem - but not a solution. I switch to virtualbox - but with virtualbox I had the problem that I ran out of memory with 10 VM's ... There any plans when that problem will be fixed or some workaround?

There is not much molecule can actually do here since the underlying problem is not in the molecule itself. The company I work for started migrating from docker to podman because running systemd in a container is supported scenario.
