AWS CDK - post deployment actions

Question

is anyone aware of a method to execute post-deploy functionality. Follwing is a sample of a casual CDK app.

app = core.App()
Stack(app, ...)
app.synth()

What I am looking for is a way to apply some logic after template is deployed. The thing is the app completes before cdk tool starts deploying template.

thanks

Edit: CDK now has https://github.com/cdklabs/cdk-triggers, which allows calling Lambda functions before/after resource/stack creation

You can't do that from CDK at the moment. See https://github.com/awslabs/aws-cdk/issues/2849. Maybe add your +1 there, let them know you'd like to see this feature.

What you can do is wrap cdk deploy in a shell script that will run whatever you need after the CDK is done. Something like:

#!/bin/sh

cdk deploy "$@"
success=$?
if [ $success != 0 ]; then
    exit $success
fi

run_post_deploy_with_arguments.sh "$@"

will run deploy with the given arguments, then call a shell scripts passing it the same arguments if deployment was successful. This is a very crude example.
