As an execution environment for CI/CD workloads, we use Concourse. We however abstract from the underlying “build executor” and instead offer a Pipeline Definition Contract, through which components declare their build pipelines as required.


In order to run continuous delivery workloads for all components contributing to the Gardener project, we operate a central service.

Typical workloads encompass the execution of tests and builds of a variety of technologies, as well as building and publishing container images, typically containing build results.

We are building our CI/CD offering around some principles:

  • container-native - each workload is executed within a container environment. Components may customise used container images
  • automation - pipelines are generated without manual interaction
  • self-service - components customise their pipelines by changing their sources
  • standardisation
