Concourse CI with Docker Compose

Upstream instructions on how to bring up a Concourse environment with Docker Compose live at http://www.concourse.ci/docker-repository.html. This repo makes those instructions easier to consume.

The fly directory contains a Dockerfile to build an image with fly installed.

Requirements

• Docker
• Python 3.6+
• pipenv
• GNU make
• ssh-keygen

Initial Setup

    $ make init

Environment Lifecycle

docker-compose is used to manage the lifecycle of Concourse containers. Helper targets in make are up, down, and ps based on their counterparts up -d, down, and ps respectively in docker-compose.

    $ make up
    $ make ps
    $ make down

A helper target to build the fly Docker image is build.

    $ make build

Run fly cli in its container.

    $ make exec
    # fly

Get a list of all make targets.

    $ make list

Caution

Cleaning up the environment is synonymous with down.

    $ make clean

Alert

Destroying the environment cleans it first then removes keys and PostgreSQL data.

    $ make destroy

Run the init target to go back to a usable state.

    $ make init

Customize

These files are prime candidates to customize for your needs.

.envrc

Modify fly version and other authentication credentials to your liking.

I've made a best-effort guess of which host IP to use for the CONCOURSE_EXTERNAL_URL environment variable. Modify it as needed.

docker-compose.yml

May not require too much attention but you never know.

Makefile

May not require too much attention but you never know.

fly/Dockerfile

Contains examples for Ubuntu 16.04 and Alpine 3.7. By default, uses Ubuntu 16.04.
