The Pulumi code is in aws-ec2/pulumi folder. The code is written in Python. In order to make it work, you have to first set up the pulumi stack itself.
Download the pulumi CLI, then hit
pulumi loginand after being redirected, authenticate yourself.
Create a new Pulumi stack via:
pulumi stackand create a new stack.
Create a new pulumi access token. If you're using pulumi.com, you can do it at https://app.pulumi.com/KNiepok/settings/tokens.
Create an AWS integration with EC2 permissions. It's best if it has a wildcard access for stack, so it can be used by all new stacks created by blueprints.
