Canonical has added an AWS Marketplace component that attaches an Ubuntu Pro subscription while an EC2 Image Builder recipe builds a custom AMI. The change matters to platform teams because it makes the entitlement part of the image pipeline rather than a manual token step. It can be used with a selected base image and then distributed with the rest of an organization’s standard AMI workflow.
What changes in the build process
Previously, a team normally began with an Ubuntu Pro base AMI or applied a token during image creation. The new component can be added to an Image Builder recipe. After the build, the subscription is attached to the resulting AMI as instance metadata. On an Ubuntu base image with ubuntu-pro-client installed, default Pro services activate at first boot.
A limitation that needs documenting
Adding the component to a non-Ubuntu host does not turn that host into Ubuntu Pro. Canonical says that case licenses the cluster to run Ubuntu Pro containers only. It does not give the host Expanded Security Maintenance, compliance hardening, or kernel livepatching. Teams using mixed Linux images should make that distinction explicit in architecture and support documents.
Five implementation points
- Select the Marketplace component matching AMD64 or ARM64.
- Grant the build role
imagebuilder:GetComponentandaws-marketplace:Subscribe. - Install
ubuntu-pro-clientin Ubuntu base images before expecting service activation. - Place the Pro component alongside hardening, monitoring, and application components in the recipe.
- Validate the finished AMI instead of relying only on a successful pipeline status.
Practical deployment checklist
- Subscribe to the Marketplace listing before a production build and assign ownership for marketplace cost control.
- Test first in a non-production account or region.
- Confirm Product codes on the AMI:

aws ec2 describe-images. - Boot a test instance, verify Pro client state, update policy, and required services.
- Test image sharing, instance launch permissions, and the organization’s normal monitoring agents.
Why it is useful
The benefit is repeatability. The subscription becomes visible in a reviewed recipe and no longer relies on a person applying a token at the right moment. It does not replace vulnerability management, image scanning, IAM design, network controls, or application testing. Image Builder creates the AMI; the organization remains responsible for the workload’s security and lifecycle.
Conclusion
This component is a good fit for teams standardizing Ubuntu Pro AMIs through AWS Image Builder. Begin with a test recipe, verify architecture and product codes, and confirm behavior after boot. Keep the non-Ubuntu container-only limitation front and center so service expectations remain accurate.

Operational validation and ownership
Run repeat builds to confirm that the component behaves consistently across the target account, region, and architecture. Verify that the AMI can be shared under the organization?s image policy, that an instance starts successfully in its intended subnet, and that endpoint or monitoring agents do not interfere with Pro activation. These tests catch Marketplace permission mistakes and architecture differences before the AMI is placed in a production catalog.
Assign clear ownership for the recipe, Marketplace subscription, and image lifecycle. A recipe should state its base AMI, component versions, security updates, test result, and retirement date. Review it when Ubuntu Pro services, AWS Image Builder components, or account permissions change. A predictable rebuild process is safer than patching a long-lived golden image by hand.
Decision guide
Use the component when Ubuntu Pro entitlement needs to be repeatable inside an AWS-native AMI pipeline. Do not use it as a substitute for choosing a supported operating system, reviewing vendor terms, or testing the application workload. The final test is simple: a freshly launched instance must have the expected entitlement, security services, application behavior, and operational visibility.
