The Sagan application is continuously built, tested and deployed in production with Concourse CI. You can check the status of the Concourse pipeline at any time on our Concourse instance.
Sagan is made of several applications, including the website itself, sagan-site.
The Sagan pipeline has a job for each application, but they’re all quite similar.

Everything you need to deploy an identical Concourse pipeline is here. The pipeline.yml file
describes the resources, jobs and steps that make the Sagan pipeline. It is referencing the
various tasks and CloudFoundry manifests as external files under the concourse folder.
Some job steps require credentials and secrets; instead of adding them to pipeline.yml file
(and to the commit history), they can be stored in a separate (private) file or in a
credentials manager. You can spot those ((parameters))
in the pipeline description.
To deploy the pipeline to an existing Concourse instance, in a existing sagan target, you
can run the following command using the fly CLI:
$ cd sagan/concourse
$ fly --target sagan set-pipeline --pipeline=sagan --config=pipeline.yml --load-vars-from=credentials.yml
