In this lesson you will learn how to run jobs that require a CMS-specific software stack and how to access protected files in GitLab CI using the GitLab installation at CERN. We will use the use case of running CMS software (CMSSW) jobs as an example.
Prerequisites
Basic understanding of the purpose of GitLab CI and of its use, as described in the HSF tutorial. Basic understanding of using and developing in CMSSW.
