Rally + GitHub

A GitHub App in active development built with Probot that integrates Rally (a project management tool) with GitHub. It can be configured to:

• Check the title of a Pull Request for valid Rally artifacts
• Check the body of a Pull Request for valid Rally artifacts
• Check the commit messages of a Pull Request for valid Rally artifacts

The GitHub App will update the Checks API with success/failure as the conditions are met, and provide a detailed report of the artifacts (i.e. defects, user stories) found and their Flow States in Rally.

Get Started

How it Works

Every time a pull request is created or updated, Rally + GitHub will check for the existence of a Rally User Story or Defect in the title, body, or commit messages, and then validate that they are in the correct state in Rally.

---
# Name of the GitHub Check
checksName: integrations/rally

# Check PR Body for Rally story/defect (true | false)
checkPRBody: true

# Check PR Title for Rally story/defect (true | false)
checkPRTitle: true

# Check all commit messages for a Rally story/defect (true | false)
checkCommitMessages: true

# Set Rally Flow State to Complete on merge if the PR Body contains "/completes <DEFECT/STORY ID>"
mergeOnPRBody: true

# Comment on the PR in addition to the check message? (true | false)
commentOnPull: false

Creating the GitHub App on your GitHub instance

• You can follow the detailed documentation at Creating a GitHub App. Below is the condensed version of the documentation

• On your GitHub instance, visit the settings page on the Organization that you want to own the GitHub App, and navigate to the GitHub Apps section.

  • You can access this page by visiting the following url: https://<MY_GITHUB_HOSTNAME>/organizations/<MY_ORG_NAME>/settings/apps

• Create a new GitHub App with the following settings:

  • Webhook URL: URL of the machine on which this app has been deployed (Example: http://ip.of.machine:3000)
  • Homepage URL: URL of the machine on which this app has been deployed (Example: http://ip.of.machine:3000)
  • Webhook Secret: REQUIRED The webhook secret that will be or has been defined as an environment variable in your deployment environment as WEBHOOK_SECRET
  • Permissions:
    • Checks: Read & write
    • Commit statuses: Read & write
    • Contents: Read-only
    • Metadata: Read-only
    • Pull Requests: Read & write
    • Issues: Read & Write
  • Events:
    • Pull request
    • Check run
    • Check suite
    • Push

• Once these have been configured, select the Create GitHub App button at the bottom of the page to continue

• Make a note of the APP ID on your newly-created GitHub App. You will need to set this as an environment variable when you configure the app.

• Generate and download a private key from the new App page, and store it in your deployment environment. You can either do this by saving the contents of the key file as the environment variable PRIVATE_KEY, or by saving the file directly in the environment and specifying its path with the environment variable PRIVATE_KEY_PATH

• After you have created the GitHub App, you will need to install it to the desired GitHub Organizations.

  • Select Install App
  • Select All Repositories or the desired repositories you wish to watch

Deployment

Rally + GitHub is based on the Probot framework and can be deployed as a standard NodeJS application. Ensure that NPM is installed in your deployment environment. Also ensure that the following environment variables are configured. Note: You can also deploy as a Docker container. Please view the Docker Deployment Doc for more info.

# Clone repository to local machine
git clone https://github.com/github/rally

# Change directories into code base
cd rally

# Install all dependencies
npm install

# Create the .env configuration file and update with all needed variables
cp .env.example .env
vi .env
# update .env with configuration variables

# Run the bot
npm start

# Run the bot in the background and output to log
# there are other major ways to achieve this...
# https://github.com/unitech/pm2
# https://github.com/github/auto-fork-sync#running-with-systemd
# https://www.npmjs.com/package/forever
nohup npm start 2>&1 >> /path/to/output.log &

Environment Variables

• APP_ID - The App ID of the GitHub App
• BOT_NAME - The name of the bot
• WEBHOOK_SECRET - The secret to prevent man in the middle attacks
• GHE_HOST - This is a required field for GitHub Enterprise Server implementations (Example: github.mycompany.com)
• RALLY_SERVER - URL to connect to Rally
• RALLY_USERNAME - Username to authenticate to Rally
• RALLY_PASSWORD - Password to RALLY_USERNAME to authenticate to Rally (Note: RALLY_API_KEY is preferred method)
• RALLY_API_KEY - API key to authenticate to Rally instead of RALLY_USERNAME and RALLY_PASSWORD
• ENFORCE_ALL_REPOS - true or false, will set enforcement of Rally + GitHub on all repositories in the installed Organization
• ORG_CONFIG_REPO_NAME - Repository name where an organization-level configuration can set default behavior for all repositories (Default: .github)

One of the following is required:

• PRIVATE_KEY - The contents of the private key for your GitHub App. If you're unable to use multi-line environment variables, use base64 encoding to convert the key to a single line string.
• PRIVATE_KEY_PATH - The path to the .pem file for your GitHub App. (Example: PRIVATE_KEY_PATH='path/to/key.pem')

How users can consume Rally + GitHub App

Once you have the GitHub App up and running, users will need to add the configuration file to master branch to have the GitHub App validate their repositories: .github/rally.yml

• Having this file in the root of the repository is what signals the Rally + GitHub App to view all configured events for the repository
• The configuration file allows users to make small customizations to how the bot interacts with their codebase
• Users will also want to configure protected branches to help make sure all rules are followed and enforced by the validator bot
• If a default configuration for all repositories in an organization is desirable, create a .github/rally.yml file in a repository called [ORG_NAME]/rally-github-config. The name of this configuration repository can also be set as an environment variable.
• If a per-repository configuration needs to be managed from a central repository, create a .github/rally/[REPO_NAME].yml file in a repository called [ORG_NAME]/rally-github-config instead.
