GitLab ce upgrade from 10.8 to 11.11 (docker/kubernetes)

Hello, I am trying to upgrade GitLab CE from 10.8.7 to 11.11.0 (latest) running on kubernetes.
I just changed the docker image of the gitlab omnibus pod, but after several messages I get:

Running handlers:
Running handlers complete
Chef Client finished, 331/986 resources updated in 01 minutes 19 seconds

gitlab Reconfigured!
Running Post Reconfigure Script...
Please specify a valid ruby command or the path of a script to run.
Run 'bin/rails runner -h' for help.

undefined method `include' for #<Rails::Command::RunnerCommand:0x00007fbe3a4a12d0>

Then the pod is restarted and the script restart (until the pod status becomes “crashloopbackoff”).
Any hint?

[EDIT] the problem seems related to version 11.11.0-ce. No problem using 11.10.4-ce
