Run hostnamectl in Arch Linux Docker container (Ansible/Molecule)

Hi all!

At first: I hope I'm in the right sub-forum!

I want to create a role for Ansible to configure my network. I'm also trying to test my role with molecule in an Arch Linux Docker container.
Inside my role I'm using Ansible's hostname module. But when I run my molecule test I get the following error message: "Could not set property: Failed to set static hostname: Device or resource busy."

I'm new to Docker, so maybe its some missing capabilities in my configuration. Maybe something is wrong in my Dockerfile. But maybe its not possible at all to get the hostnamectl command running in an Arch Linux Docker container.
I've installed the inetutils package and ran the hostname command, which worked. But at least Ansibles hostname module doesn't care about the hostname command.

I hope you can give me some information on my questions!

Here are the files I'm using:

network/defaults/main.yml

Thanks for your help!
