Since about a year now, 1&1 is running Kubernetes clusters as a general purpose platform. Recently having grown out of our beta definition, I will show what we built and how we manage running, updating and configuring one specific group of internal clusters by using Gitlab-CI Pipelines.

* How to automate cluster operation workflows with GitLab
* How to ease multi-tenancy configuration
