[coreycarvalho]

User Story - Business Need

We want to enable Seekable OCI (SOCI), which is a way to index and lazy load images, to improve startup times for ENP containers.

• Sync with Kyle when ticket is picked up.
• Ticket is understood, and QA has been contacted (if the ticket has a QA label).

User Story(ies)

As a DevOps Engineer working on VA ENP API
I want to implement Seekable OCI (SOCI) to enable lazy loading of container images
So that we can reduce container startup time and improve deployment efficiency

Additional Info and Resources

• AWS SOCI documentation: https://aws.amazon.com/blogs/containers/seekable-oci-soci-a-technology-for-faster-container-startup/
• SOCI GitHub repo: https://github.com/awslabs/soci-snapshotter
• SOCI enables lazy loading without modifying the original OCI image, maintaining image integrity and signatures.
• We will use soci-snapshotter with containerd to support indexed container images.

Acceptance Criteria

• SOCI indexing is successfully generated for the VA ENP API container images.
• The SOCI index is stored in our OCI registry and correctly references container images.
• The soci-snapshotter is integrated with containerd to enable lazy loading.

QA Considerations

Potential Dependencies

• Requires containerd support for soci-snapshotter.
