  3. Create the manifest list. 
    docker manifest create --insecure localhost:15000/testing/testing-build:1.0 localhost:15000/testing/testing-build:arm64v8-1.0 localhost:15000/testing/testing-build:amd64-1.0
Created manifest list localhost:15000/testing/testing-build:1.0
  4. Push the manifest list. 
    docker manifest push --insecure localhost:15000/testing/testing-build:1.0
sha256:6f4eb514d2427f874bc2176111a794a1fcaf49bbdd2d87ac95075799b5bf281b
  5. docker pull with the manifest list tag. 
    docker pull localhost:16000/testing/testing-build:1.0
1.0: Pulling from testing/testing-build
Digest: sha256:6f4eb514d2427f874bc2176111a794a1fcaf49bbdd2d87ac95075799b5bf281b
Status: Downloaded newer image for localhost:16000/testing/testing-build:1.0
localhost:16000/testing/testing-build:1.0
  6. The pulled image localhost:16000/testing/testing-build:1.0 has the same image ID as the images with amd64-1.0 tag. This is because the platform of the local machine is amd64.
