Const ExperimentalDocker defines a sha256 of the image id; container.image.id corresponds to the Image field from the Docker container inspect API endpoint.
K8s defines a link to the container registry repository with digest "imageID": "registry.azurecr.io /namespace/service/dockerfile@sha256:bdeabd40c3a8a492eaf9e8e44d0ebbb84bac7ee25ac0cf8a7159d25f62555625".
The ID is assigned by the container runtime and can vary in different environments. Consider using oci.manifest.digest if it is important to identify the same image in different environments/runtimes.
This attribute is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
Runtime specific image identifier. Usually a hash algorithm followed by a UUID.
