This repository collects up all that tribal wisdom we've gained from building Concourse Pipelines for various different purposes. Each template provides a base ci/pipeline.yml that structures the pipeline, ci/settings.yml to override any parameters defined by the template, a set of scripts (in ci/scripts/) that are referenced from the pipeline, and a ci/repipe utility for putting all the pieces together into a functioning Concourse pipeline.

This project was initially created by Stark & Wayne, and is now maintained by Gstack.

Setup is straightforward:

git clone https://github.com/cloudfoundry-community/pipeline-templates
cd pipeline-templates
./setup <template> ~/bosh/my-new-boshrelease

Alternatively, you can initialize the pipeline from inside the target repository:

cd code/my-buildpack
~/code/pipeline-templates/setup <template>

The first argument to setup is the template you want to use. Currently available templates:

• bash
• boshrelease
• genesis-kit
• buildpack
• cfpush
• docker/base
• docker/ext-tests
• go
• helm

Don't let the name fool you! ./setup can also be used to update an existing templated pipeline ci/ directory to pick up new changes made to the templates.

Once you've set up your repository, you'll need to fill in your ci/settings.yml file with any parameters the template required:

cd code/my-project
ci/repipe # Attempt to update the pipeline config,
          # spitting out errors for missing parameters
vi ci/settings.yml # fill in the missing parameters
ci/repipe # Deploy the pipeline config!

The ci/repipe script uses Spruce to merge ci/pipeline.yml and your bespoke ci/settings.yml.

On MacOS/Homebrew:

brew install cloudfoundry-community/cf/spruce

On Debian/Ubuntu:

wget -q -O - https://raw.githubusercontent.com/cloudfoundry-community/homebrew-cf/master/public.key | apt-key add -
echo "deb http://apt.community.cloudfoundry.org stable main" | tee /etc/apt/sources.list.d/cf-community.list
apt-get update

apt-get install spruce

The ci/repipe for genesis-kits also requires jq, which can be installed via brew on MacOS or apt-get on Debian/Ubuntu.

For building Docker images, with tests. This template comes in two flavors: docker/base (where the unit tests are inside the Docker image) and docker/ext-tests, where the tests live outside of the image.

Takes a Go software project repository, runs unit tests and (when the manual shipit job is run) releases to Github.

Tries to create a BOSH release from the repository, upload it to a hosted BOSH-lite for viability testing, and (when the manual shipit job is run) releasing it to Github with a tarball artifact, and also uploading that release tarball to S3.

Builds a pipeline to create a pipeline that builds a release candidate, runs it through spec tests and spec-check, then any deployment, upgrad and acceptance tests. Passing those, it prepares the release notes based on commit messages, and then can be manually released. It also includes a manual prerelease after the initial RC is built.

There is also provision for pulling upstream dependencies and bumping semantic version components.

Read the README.md file under genesis-kit for customization options. As written, it is based on the cf-genesis-kit.

Runs unit and integration tests on a Cloud Foundry buildpack, and can release it to Github.

Builds a docker image and uploads Helm chart to an S3 bucket

You will need to customize your pipeline with information about your CI, your Amazon AWS credentials + S3 bucket for storing assets + version file, your Slack account, etc.

You will create and maintain ci/settings.yml for this.

Try very very hard to not modify ci/pipeline.yml. Instead, use ./setup to update ci/pipeline.yml with new changes from this repo. If you do need to modify ci/pipeline.yml please feel welcome to submit PRs to this repo so that we can merge them and share them with everyone.

For those who use Vault to store their credentials, the spruce syntax (( vault "path1" )) can fetch the secret values during ci/repipe. Using this feature is not recommended though, because the secrets will leak as clear-text in the Concourse (Postgres) database. Since Concourse CI has native support for Vault, everyone should use that so that secrets are fetched just-in-time, and have lower risk of leaking.

Here is an example ci/settings.yml from the eden CLI project (uses the go template):

---
meta:
  name: eden
  target: sw
  url:     https://ci.starkandwayne.com

  initial_version: 0.5.0

  go:
    binary: eden
    cmd_module: .

  aws:
    access_key: (( vault "secret/aws/starkandwayne-s3:access" ))
    secret_key: (( vault "secret/aws/starkandwayne-s3:secret" ))
    region_name: eu-central-1

  slack:
    webhook: (( vault "secret/pipelines/eden/slack:webhook" ))
    channel: "#eden" # https://openservicebrokerapi.slack.com/messages/C6Y5A2N8Z/
    username: starkandwayne-ci
    icon:     https://www.starkandwayne.com/assets/images/shield-blue-50x50.png

  github:
    owner: starkandwayne
    repo: eden
    access_token: (( vault "secret/pipelines/shared/github:access_token" ))
    private_key: (( vault  "secret/pipelines/shared/github:private_key" ))

Bonus, we use https://github.com/starkandwayne/safe as our CLI to interact with Vault.

For example, to populate the (( vault "secret/pipelines/eden/slack:webhook" )) value in Vault:

safe set secret/pipelines/eden/slack webhook=https://hooks.slack.com/services/T2S1X7xxx/B6Y5A7xx/0nP7jxxx
