A simple lambda function that gets triggerred in response to an AWS CodeCommit repository events and update the team in slack.

1. Pre-Requisities

   We will need the following pre-requisites to successfully complete this activity,

   • AWS CodeCommit Repo - Get help here to setup CodeCommit Repo
   • IAM Role - i.e Lambda Service Role - with managed permissions Get Help for setting up IAM Role
     • AWSLambdaBasicExecutionRole - To allow Lambda to log events
     • AWSCodeCommitReadOnly - To allow Lambda to read repo metadata

2. Configure Lambda Function

   • The python script is written(and tested) in Python 3.7.
   • Copy the code from serverless-code-commit-repo-event-notifier in this repo to the lambda function
   • Optional: Add slack slack_webhook_url in the environment variable
   • Save the lambda function

3. Configure Lambda Triggers

   • Choose AWS CodeCommit from the list of services.

   

   • In Repository name, choose your repository name.

   • In Trigger name, enter a name for the trigger.

   • In Events, choose the repository events that trigger the Lambda function, for example, choose All repository events.

   • In Branches, Choose All branches, if you want the trigger to apply to all branches of the repository.

   • In Custom data, Optional: Leave empty for now.

   • Choose Next.

   Now your lambda function should be triggered when ever there is a CodeCommit event in your repository

4. Testing the solution

   Create a new commit/branch in your repo, you should be getting the message in Slack(if configured).
