Concourse is a CI system composed of simple tools and ideas. It can express entire pipelines, integrating with arbitrary resources, or it can be used to execute one-off builds, either locally or in another CI system.
Concourse is inspired by BOSH and Diego. It is deployed and configured with BOSH, and leverages garden for containerization across platforms. I’ll cover what shortcomings of other CI systems Concourse addresses, and how the Diego team uses concourse.
