Domain expertise for creating and managing EC2 Image Builder pipelines that automate custom AMI creation. Covers the full lifecycle: IAM role setup, build component definition, image recipe creation, infrastructure and distribution configuration, pipeline execution, and launch template creation.

To create a complete EC2 Image Builder pipeline with custom AMI builds and cross-region distribution, follow the procedure exactly. See EC2 Image Builder pipeline procedure.

Use the exact ARN returned by API calls — do not construct ARNs manually. Pipeline ARNs must follow .

Wait 10–15 seconds after creating the instance profile before using it. IAM changes are eventually consistent.

Delete the existing resource first or use a different name/version.

Verify the instance profile exists, all three IAM policies are attached, and the instance type is available in the region.
