-[Tests](https://gitlab.cern.ch/linuxsupport/testing/) are in place to check everything is working as expected. If you want to skip them, run a pipeline with variable `CI_SKIP_TESTS="true"`. This can be done through CI/CD -> Pipelines -> Run pipeline -> Select branch, add the variable, press run. This will override globally defined variables in the CI.

-A scheduled pipeline rebuilds the image once per month.
