Docker gitlab-ce-qa not running properly

I’m new to the gitlab qa framework and want to test it in order to automate some testing processes.
I thought the easiest way to get used to the framework is to run the system in a fully configured state as the docker image gitlab/gitlab-ce-qa:nightly.

Unfortunately the image does not run and the following error is displayed
“warning: parser/current is loading parser/ruby27, which recognizes
warning: 2.7.1-compliant syntax, but you are running 2.7.4.”

Is there any other docker image which I can use? In case there is none, then I would appreciate some instruction how to fix the container or setup my local machine from scratch.

Thank you very much in advace.

Best regards
