Containerized

You can import the JSON keys service as a container. You need to import both API and associated Jobs for the service to run correctly.

podman

Standalone image (local)

For local development or CI purposes, you can also load a standalone version that runs all the necessary jobs before starting the service.

WARNING

The standalone image takes longer to boot, and it is not suited for production use.
