bitbucket-slack-pr-hook

Receive Pull Requests notifications from Bitbucket and send them to Slack.

Features

As for 2014-09-26 we support all BitBucket's action types:

• created
• updated
• approve
• unapprove
• declined
• merged
• comment_created
• comment_deleted
• comment_updated

See Bitbucket's official docs: Pull Request POST hook management

Caveats

Bitbucket does not provide all necessary data in actions responses. For example, for a comment_* action we don't have the PR number, link nor name. So all we can do is something like "Comment posted for a PR" and then the snippet of the comment. But currently there's no way to know where did this comment came from.

Requirements

• Bitbucket repository with admin rights
• Slack Incoming Webhook Url: Get your Slack token from your "integrations" page
• Node.js OR Docker

Optional Features

Mention reviewers

If you want to automatically notify the PR reviewers, you can set to true the environment variable MENTION_REVIEWERS.

It will assume that the Bitbucket username will be the same in Slack. If not, the user could add a "highlight word" in their preferences for their username used in Bitbucket.

Configuration

The configuration variables are set with environment variables and/or using .env file (environment variable takes preference over .env file if found).

Environment Variable	Required	Description	Example
SLACK_WEBHOOK	Y	The incoming hook url found on your Slack team's integration page	https://hooks.slack.com/services/XX/XXX/XXXX
SLACK_USERNAME	N	Username of the Slack bot. If not set, bot will default to integration settings.	BitbucketNotification
SLACK_CHANNEL	N	Channel to post notifications on. If not set, bot will default to integration settings.	RepositoryUpdate
MENTION_REVIEWERS	N	Set to true if you want to mention reviewers in slack channel	false
HEX_INFO	N	Hex color of updated, and created	#3498db
HEX_DANGER	N	Hex color of declined	#e74c3c
HEX_WARNING	N	Hex color of unapprove, comment: created, comment: deleted, and comment: updated	#f1c40f
HEX_SUCCESS	N	Hex color of merge, and approve	#2ecc71

If you want to use .env file, copy the example.env as .env and modify it as needed. Your configuration would look like the example below:

PORT=5000
SLACK_WEBHOOK=https://hooks.slack.com/services/A123ka9/A123910a9d8/mkas929199sad83lmk7h
SLACK_USERNAME=AwesomeBot
SLACK_CHANNEL=Repository
HEX_SUCCESS=#2ecc71
HEX_DANGER=#e74c3c

Note: Setting the SLACK_USERNAME or SLACK_CHANNEL will override the settings set on the incoming webhook integration page. If you want your team to edit any of these settings without redeploying, do not add them to your .env file.

Important: if you're going to use a .env file AND using Docker, edit it before building the Dockerfile.

When running the service in Docker container, the config values can be provided as parameters:

# Starts Docker container in daemonized mode
docker run -e PORT=5000 -e SLACK_TOKEN=123123 \
  -e SLACK_DOMAIN=company -e SLACK_CHANNEL=channel \
  -p 5000:5000 -d bitbucket-slack-pr-hook

Automated Installation

Manual Installation

• Local Infrastructure or Cloud Services
• Docker

Local Infrastructure or Cloud Services

1. Set up a server address in your local infrastructure that will serve this application (eg: slackapi.mycompany.com or slackapi.heroku.com)
2. Clone/download this repo to your chosen server
3. Configure your application according to the "Configuration" section above
4. Install NodeJS if you don't have it
5. Run npm install in the app's root folder

Important note: make sure you don't have any firewall blocking the incoming TCP port (default is PORT 5000 as defined in the "Configuration" section above)

Docker

Service can also be installed & deployed using Docker containers, which makes it easy to setup the environment without worrying about the requirements.

1. Clone/download this repo

2. Install Docker (using system packages in Linux, in Windows or Mac OS X you can use Boot2docker)

3. Start Docker service (or boot2docker up)

4. Build the Docker image:

   Alternatively: npm run build-container

   docker build -t bitbucket-slack-pr-hook .

5. Start container with appropriate -e config parameters:

   docker run -e PORT=5000 -e SLACK_WEBHOOK=webhookurl
   -p 5000:5000 -d bitbucket-slack-pr-hook

6. Ensure the container is running (you should also be able to access the service using web browser: http://<dockerhost>:5000/).

   Note: In Linux the <dockerhost> is localhost, with Boot2docker use the IP reported by the command: boot2docker ip

Setting up the Bitbucket Repository

1. In your main Bitbucket repository, go to Settings > Hooks and create a new Pull Request POST hook
2. Set up the URL as http://<server>:<port>{/<channel>}. * <server> is your host FQDN or its IP address * <port> is either 5000 or any other you defined in the configuration section * <channel> is an optional Slack channel where you want to receive this specific notifications - if it's not defined here it will use the one you defined in Configuration -section.

Activate

Via plain node

1. Run npm start (or node server.js) to fire up the application (you can do node server.js & to run it as a daemon in your Linux box)

Via Docker

1. Run npm run build-container to build the container
2. Run npm run start-container to start the container and the server inside it
3. When needed, you can use npm run stop-container and npm run reload-container
