    LTS images are stable and usually include latest bug and security fix.
    'image' should be used to specify the image.

  * To integrate continuously with other container
    related technologies like runc, containerd, docker and kubernetes, the
    latest LTS or stable images are preferred. 'image_family' should be used to
    specify the image.
