In this episode, we explore how powerful CDK pre-deployment hooks can be, including the fact that you can run virtually any logic before a deployment like publishing messages to EventBridge or writing an item to a DynamoDB table to trigger DynamoDB Streams. After defining the pre-deployment hook, we jump back into the CDK code to complete the setup by granting the hook the permissions it needs to invoke a Lambda function.

We Are .NET

Pre-deployment hooks in serverless AWS CDK setups can execute arbitrary logic before a deployment completes, such as publishing to EventBridge, writing to DynamoDB to trigger streams, or invoking Lambda functions. The snippet demonstrates granting a pre-deployment hook the necessary IAM permissions to call a Lambda function.
