vcn supports local Docker installations out of the box using docker:// as a location. You just need to point to the correct container image name or the container image id.
vcn uses Docker default schemes, so the latest tag is automatically used if no tag is given. For example:
vcn notarize docker://hello-world
Or use the command with a tag:
vcn notarize docker://hello-world:v1
