31.2 Pulling a Container Image

For this example, the most recent Ubuntu release will be pulled from the registry. Before pulling an image, however, information about the image repository can be obtained using the skopeo tool, for example:

$ skopeo inspect docker://docker.io/ubuntu

{

    "Name": "docker.io/library/ubuntu",

    "Digest": "sha256:bec5a2727be7fff3d308193cfde3491f8fba1a2ba392b7546b43a051853a341d",

    "RepoTags": [

        "10.04",

        "12.04.5",

        "12.04",

        "12.10",

        "13.04",

        "13.10",
