 **[1]:** Docker defines a sha256 of the image id; `container.image.id` corresponds to the `Image` field from the Docker  container inspect [API](https://docs.docker.com/engine/api/v1.43/#tag/Container/operation/ContainerInspect)  endpoint.
 K8s defines a link to the container registry repository with digest `"imageID": "registry.azurecr.io /namespace/service/dockerfile@sha256:bdeabd40c3a8a492eaf9e8e44d0ebbb84bac7ee25ac0cf8a7159d25f62555625"`.
