# Buildkite Monorepo Example

Example monorepo using buildkite plugin [buildpipe](https://github.com/jwplayer/buildpipe-buildkite-plugin/).

The monorepo config lives in [.buildkite/pipeline.yml](./.buildkite/pipeline.yml).

You can see there are 3 projects defined.

The config shows steps the projects share with their associated commands. The commands are standardized using `make` and Makefile inheritance.

## Getting started

1. Create the initial pipeline:

    ```yaml

    steps:

      - label: ":buildkite:"

        plugins:

          - jwplayer/buildpipe#v0.9.1:

              dynamic_pipeline: .buildkite/dynamic_pipeline.yml

    ```

1. Generate deploy key and change permissions

    ```bash

    # Start ssh agent in the background

    eval "$(ssh-agent -s)"

    # Generate ssh key

    make generate-deploy-ssh-key

    chmod 600 ~/.ssh/id_rsa_buildkite_git

    # Create agent socket

    ssh-agent -a ~/.ssh/ssh-agent.sock

    # Add ssh key

    ssh-add ~/.ssh/id_rsa_buildkite_git

    # Test key works

    # https://developer.github.com/v3/guides/using-ssh-agent-forwarding/

    ssh -T [email protected]

    ```

1. Add the public key `~/.ssh/id_rsa_buildkite_git.pub` to your Github repo under Settings > Deploy keys.

1. Run the buildkite agents locally:

    ```bash

    # Make sure to add to .bashrc

    export SSH_AUTH_SOCK=$HOME/.ssh/ssh-agent.sock

    export BUILDKITE_AGENT_TOKEN=

    # Run agent in a docker container scaled to the number of cpus

    cd buildkite-agent/ && make local

    ```

You should see the number of agents at the top bar in Buildkite appear.

## Examples

The following examples shows how the pipeline creation is dynamic depending on which projects

were changed.

1. Updating primer project in master only triggers the primer pipeline to run

    ![Update single project](images/2-update-primer.png)

1. Updating both primer and hubot projects in master triggers both pipelines

    ![Update multiple projects](images/3-update-primer-and-hubot.png)
