3 Project

Concourse began as a side-project by @vito and @xoebus in 2014. Since then, Concourse has evolved into a dedicated community with contributors from all around the world.

Concourse is a project of the Cloud Foundry foundation (CFF), currently lead by Taylor Silva and Derek Richard. The CFF pays for the infrastructure costs of the project. Pixel Air IO, lead by Taylor, is currently the main developer behind Concourse; reviewing and merging Pull Requests, squashing bugs, and stewarding the project and community.

Where is everything?

  • The Concourse repo houses the main codebase, where planning happens, and where issues are tracked.

  • The Docs repo contains the source for the website you're reading now!

  • GitHub Discussions are used for support, announcements, idea sharing, and general conversations.

  • The Concourse blog features tutorials and updates from the development perspective.

  • The Concourse Discord server offers a great space to chat with other contributors.

  • The Concourse working group charter is available in the Cloud Foundry community repo.

  • The working group holds public monthly meetings. Past meetings can be viewed in this YouTube playlist and meeting notes are here.

Why make Concourse?

When working on a substantial project, having a pipeline to reliably test, deploy, and publish the product is essential for rapid iteration.

But with every CI system we tried, we found ourselves repeatedly facing the same problems: complex configs buried in many pages of the web UI, uncertainty about who changed what & when, managing dependencies and state on the workers, build contamination, frustrating UX...

Our project was expanding, and with every box we checked and for every worker we manually configured, the anxiety of having to rebuild everything if something failed grew increasingly. We began writing software to manage our CI instead of creating the software for the product we intended to build.

We created Concourse to be a CI system that provides peace of mind. A CI that's straightforward enough to fully understand and easy to maintain as your project grows; both in the complexity of the product and the size of your team. We aimed to build a CI with robust abstractions and fewer concepts to learn, making it easier to comprehend and allowing Concourse to evolve gracefully.

How can I help?

Thanks!

It's been a long journey and we're grateful to many people for our continued success. We are deeply indebted to all who help sustain this project, but the extraordinary efforts of the following organizations deserve special recognition.

Pivotal

Concourse wouldn't be what it is today without Pivotal. This extends beyond the sponsorship, which began in early 2015 - without the experiences we gained and the practices we learned while working on Cloud Foundry and BOSH, we would have neither the technical expertise nor the strong opinions that led to Concourse's creation.
