--- name: creating-ec2-image-builder-pipeline description: Creates a complete EC2 Image Builder pipeline that builds a custom AMI with pre-installed software, distributes it to target regions, executes the pipeline, and creates a launch template. Use when setting up automated AMI creation with IAM roles, build components, image recipes, and infrastructure configuration. version: 1 --- # 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](references/ec2-image-builder-pipeline.md). ## Troubleshooting ### InvalidParameterValueException on pipeline operations Use the exact ARN returned by API calls — do not construct ARNs manually. Pipeline ARNs must follow `arn::imagebuilder:::image-pipeline/`. ### 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.
