CC-Utils - Build Pipeline Reference Manual¶
Introduction¶
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
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.
Terms, Definitions and Concepts¶
Although we are using Concourse as underlying build scheduler, we use some terms differently as done in the context of concourse.
