Lambda deployments

New Features

Controlled, blue/green deployments of Lambda functions with (automatic) rolebacks and traffic shifting can be implemented using Lambda aliases and AWS CodeDeploy.

This release provides a new optional module to create AWS resources and permissions for creating and starting such CodeDeploy deployments as part of AWS CodePipelines.

Highlights:

• fully automated AWS CodePipelines triggered by ECR pushes of containerized Lambda functions
• creation of IAM roles with permissions following the principle of least privilege for CodePipeline, CodeBuild and CodeDeploy or bring your own roles
• optional CodeStar notifications via SNS
• ignore changes to Terraform state of your Lambda function by CodeDeploy deployments

see here for a real world example

backwards compatibility

The deployment is an optional add-on. In case you enhance existing Lambda functions using ignore_external_function_updates your function will be recreated using the new lambda_external_lifecycle resource with
a lifecycle block:

lifecycle {
    ignore_changes = [
      image_uri, last_modified, qualified_arn, version
    ]
  }
