Github-Jira-Bot

A bot for a tighter integration of GitHub into Jira and vice versa.

What the bot does

To link Jira tickets and GitHub pull request with one another, we at Liefery use Tickety-Tick. The format for title on GitHub is: [#${Jira ticket key}] ${Jira ticket summary}

The bot does two things:

When a new Pull Request has been opened it adds a comment including description and URL of the associated Jira ticket if such a ticket exists.
When a comment has been added to an issue or pull request which includes QA: the bot does the following:

When no associated ticket exists, the bot creates a ticket in the current sprint and updates the title of the Pull Request accordingly.
The bot adds everything in the GitHub comment that comes after QA: as a comment to the associated Jira ticket. The magic QA keyword can be configured.

Usage

Setup the bot on Jenkins

First you need a place for the bot to run. We at Liefery use Jenkins for this.

Create a new item from the Jenkins dashboard and choose Freestyle project
Select Git for Source Code Management:
- Repository URL: git@github.com:liefery/github-jira-bot.git
- Branch Specifier: */production
Select Trigger builds remotely (e.g., from scripts) for Build Triggers:
- Choose an Authentication Token. Remember your token as you'll need it later when adding the bot to repositories on GitHub.
Select Generic Webhook Trigger for Build Triggers:
- Add some Post content parameters (choose JSONPath as expression format):
  - ACTION => $.action
  - REPO => $.repository.full_name
  - PR_TITLE => $.pull_request.title
  - PR_TITLE => $.issue.title
  - AUTHOR => $.comment.user.login
  - PR_NUMBER => $.pull_request.number
  - PR_NUMBER => $.issue.number
  - COMMENT_ID => $.comment.id
  - COMMENT_BODY => $.comment.body
  - PR_LABELS => $.pull_request.labels[*].name
- Select Print post content
- Select Print contributed variables
Add an Execute shell build step for Build:
- Command: Paste your configuration.

Note: PR_TITLE and PR_NUMBER will be set in different ways depending on the webhook used to trigger the bot.

Adding the bot to a repository

In a GitHub repository navigate to settings/webhooks and add a new webhook using the following configuration:

Payload URL: https:/JENKINS_URL/generic-webhook-trigger/invoke?token=XXX (use the same token as configured in the Authentication Token setting of the Jenkins build it should trigger)
Content type: application/json
Choose Let me select individual events
- select Issue comments
- select Pull requests
- deselect Pushes

Setup bot accounts

It is recommended that you don't use your personal GitHub and Jira accounts for the bot.

You can create accounts on GitHub and Jira with permission to access and contribute to the repositories/projects you want to use the bot for.

Configuration

Here is a sample configuration:

export JIRA_USER = "XXX"
export JIRA_PASSWORD = "XXX"
export JIRA_URL = "https://XXX.atlassian.net"
export JIRA_PROJECT_KEY = "XXX"
export JIRA_ISSUE_TYPE = "Story"
export JIRA_FIX_VERSION_ID = "XXX"
export JIRA_SPRINT_FIELD = "customfield_XXX"
export JIRA_NEW_TICKET_TRANSITION_ID = 711
export GITHUB_USERNAME = "XXX"
export GITHUB_PASSWORD = "XXX"

export MAGIC_QA_KEYWORD = "QA:"
export MAX_DESCRIPTION_CHARS = 600
export COMPONENT_MAP = '{"repo":"component"}'


bundle install
ruby lib/run.rb

JIRA_USER: Username of a Jira account.
