Print-friendly Assignment

Instructions:

• Use gitlab private repositories for code and add https://gitlab.com/manu_j as collaborator. Email [email protected] once finished.
• You can use a webhook testing platform instead of slack but it should follow the slack webhook payload format.

Coding Challenge:

Create a ruby web application, which accepts webhook requests from github.

• When a label is added to an issue, send a notification to a slack channel.
• The slack webhook URL should be provided to the app as an environment variable - SLACK_WEBHOOK_URL .
• Set the username of slack webhook as your email.
• The notification should be “Label xxxx was added to issue 201”. The issue number should be a link to the github issue.

Extra Credit:

• Add tests and use the gitlab CI to test
• Dockerize the application
