To transfer complete CloudWatch logs to Slack after the completion of AWS CodeBuild, you can follow these steps:
- Create a new AWS Lambda function.
- Configure the Lambda function to receive CloudWatch log events as triggers.
- Create a Slack webhook to receive messages from the Lambda function.
- Write code in the Lambda function to format CloudWatch log events as Slack messages, and use the Slack webhook to post the messages to the Slack channel.
- Configure CodeBuild to send CloudWatch logs to the Lambda function after completion.
You can use AWS CloudFormation to automate the deployment of the Lambda function, webhook, and necessary permissions.
