It does not have its own issue, but fixes what I saw here: #1950 (comment)

cnquery run container bc7fbc466c7c -c "asset{ platform ids name title }"
...
asset: {
  title: "Alpine Linux v3.16, Docker Container"
  platform: "alpine"
  ids: [
    0: "//platformid.api.mondoo.app/runtime/docker/containers/bc7fbc466c7c9682217d950d935aead1f415d1b69b6e87c0b0ac801eb513feff"
  ]
  name: "musing_hermann"
}

And for non-local container images:

cnquery run container image alpine:3.8.4 -c "asset{ platform ids name title version labels }"                                                                                ✔ │ 5s │ 15:48:07

asset: {
  version: "3.8.4"
  title: "Alpine Linux v3.8, Docker Image"
  labels: {}
  platform: "alpine"
  ids: [
    0: "//platformid.api.mondoo.app/runtime/docker/images/899a03e9816e5283edba63d71ea528cd83576b28a7586cf617ce78af5526f209"
  ]
  name: "index.docker.io/library/alpine@899a03e9816e"
}

The ID was only missing for images, which weren't present in the local docker daemon.
