Creating Ec2 Image Builder Pipeline

This walks you through spinning up a complete EC2 Image Builder pipeline from scratch: IAM roles, build components, image recipes, infrastructure config, distribution settings, and a launch template at the end. It's built for automating custom AMI creation and pushing those images to multiple regions. The procedure is meant to be followed exactly, which makes sense given how finicky the ARN handling can be (don't construct them manually, apparently). Worth noting the IAM eventual consistency gotcha where you need to wait 10-15 seconds after creating instance profiles. If you're tired of manually baking AMIs or want repeatable builds for your infrastructure, this covers the full setup.
