Creating an EC2 Image Builder Pipeline
Overview
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.
Create an Image Builder pipeline
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.
Troubleshooting
InvalidParameterValueException on pipeline operations
Use the exact ARN returned by API calls — do not construct ARNs manually. Pipeline
ARNs must follow arn:<partition>:imagebuilder:<region>:<account>:image-pipeline/<name>.
InstanceProfileNotFoundException
Wait 10–15 seconds after creating the instance profile before using it. IAM changes
are eventually consistent.
ResourceAlreadyExistsException
Delete the existing resource first or use a different name/version.
Build instance fails to launch
Verify the instance profile exists, all three IAM policies are attached, and the
instance type is available in the region.
