Concourse: the continuous thing-doer

Concourse is an automation system written in Go. It is most commonly used for
CI/CD, and is built to scale to any kind of automation pipeline, from simple to
complex.

Concourse is very opinionated about a few things: idempotency, immutability,
declarative config, stateless workers, and reproducible builds.

Installation

Concourse is distributed as a single concourse binary, available on the Releases page.

If you want to just kick the tires, jump ahead to the Quick Start.

In addition to the concourse binary, there are a few other supported formats.
Consult their GitHub repos for more information:

• Docker image
• BOSH release
• Kubernetes Helm chart

Quick Start

$ wget https://concourse-ci.org/docker-compose.yml
$ docker-compose up -d
Creating docs_concourse-db_1 ... done
Creating docs_concourse_1    ... done

Concourse will be running at localhost:8080. You can
log in with the username/password as test/test.

⚠️ If you are using an M-series mac, note that they are
incompatible with the containerd runtime until
#9182 is resolved.
After downloading the docker-compose file, change:

CONCOURSE_WORKER_RUNTIME: "containerd" to

CONCOURSE_WORKER_RUNTIME: "houdini".

Next, install fly by downloading it from the web UI and target your local
Concourse as the test user:

$ fly -t ci login -c http://localhost:8080 -u test -p test
logging in to team 'main'

target saved

You can follow our Getting Started Tutorial
to learn how to write Concourse pipelines.

Configuring a Pipeline

Concourse has no GUI for configuration. Instead, pipelines are defined in
declarative YAML files:

resources:
- name: booklit
  type: git
  source: {uri: "https://github.com/concourse/booklit"}

jobs:
- name: unit
  plan:
  - get: booklit
    trigger: true
  - task: test
    file: booklit/ci/test.yml

Most operations are done via the accompanying fly CLI. If you've got Concourse
installed, try saving the above example
as booklit.yml, target your Concourse
instance, and then run:

fly -t ci set-pipeline -p booklit -c booklit.yml

These pipeline files are self-contained, making them easily portable between
Concourse instances.
