wercker-bundle-update-pr

This is an automation script to bundle update and send pull request via Wercker's Trigger Build API. By requesting trigger build to Wercker with an environment variable which instruct wercker.yml to execute this script, bundle update is invoked, then commit changes and send pull request to GitHub repository if there some changes exist.

(Both concept and implementaion are strongly based on circleci-bundle-update-pr.

$ gem install wercker-bundle-update-pr

The application on which you want to execute bundle update automatically must be on a Wercker CI.

A GitHub personal access token is required for sending GitHub pull request. Go to your account's settings page and obtain a personal access token.

A Wercker personal token is required for invoking Trigger Build API. Go to your account's settings page and obtain a personal token.

In the application's setting page:

1. Generate SSH key named "wercker_github_ci_key" in "SSH Keys" for pushing changes to GitHub
2. Register the above generated key to GitHub SSH keys in Personal settings
3. In "Environment variables", add GITHUB_ACCESS_TOKEN with a GitHub personal access token (Make sure you mark it "protected" otherwise it will be shown in logs)
4. In "Environment variables", add WERCKER_GITHUB_CI_KEY as SSH key pair and select "wercker_github_ci_key"

Add the following 2 steps under steps to access GitHub via SSH (Set GitHub's SSH key RSA fingerprint to <fingerprint>. See What are GitHub's SSH key fingerprints?):

    - add-ssh-key:
        keyname: WERCKER_GITHUB_CI_KEY

    - add-to-known_hosts:
        hostname: github.com
        fingerprint: <fingerprint>

then add this step as well (replace <username> and <email> with yours).

    - script:
        code: |
          if [ "${BUNDLE_UPDATE}" ] ; then
            gem update bundler -N
            gem install wercker-bundle-update-pr -N
            wercker-bundle-update-pr <username> <email>
          fi

Do not forget git commit and git push these changes.

Now all set to fire Trigger build API.

$ curl -H 'Content-Type: application/json' -H "Authorization: Bearer <wercker personal token>" -X POST -d '{"applicationId": "<wercker application id>", "branch":"master", "message":"bundle update via trigger build", "envVars":[{"key":"BUNDLE_UPDATE","value":"true"}]}' https://app.wercker.com/api/v3/builds

You have to replace <wercker personal token> with your Wercker personal access token, and replace <wercker application id> which you can find in the URL of your wercker application.
