OPTIONS

       See also skopeo(1) for options placed before the subcommand name.

       --authfile path

       Path  of  the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json, which is set using
       skopeo login.
         If the authorization state is not found there, $HOME/.docker/config.json is checked, which is set using
       docker login.

       --creds username[:password] for accessing the registry.

       --cert-dir path

       Use certificates at path (*.crt, *.cert, *.key) to connect to the registry.

       --retry-times

       The number of times to retry. Retry wait time will be exponentially increased  based  on  the  number  of
       failed attempts.

       --tls-verify=bool

       Require  HTTPS  and  verify  certificates  when  talking  to the container registry or daemon. Default to

       --username

       The username to access the registry.

       --password

       The password to access the registry.

REPOSITORY NAMES

       Repository names are transport-specific references as each transport  may  have  its  own  concept  of  a
       "repository" and "tags".

       This  commands  refers  to  repositories  using  a  transport:details  format.  The following formats are
       supported:

       docker://docker-repository-reference
         A repository in a registry implementing the "Docker  Registry  HTTP  API  V2".  By  default,  uses  the
       authorization  state  in either $XDG_RUNTIME_DIR/containers/auth.json, which is set using (skopeo login).
       If the authorization state is not found there, $HOME/.docker/config.json is checked, which is  set  using
       (docker login).
         A  docker-repository-reference  is of the form: registryhost:port/repositoryname which is similar to an
       image-reference but with no tag or digest allowed as the last component (e.g no :latest or @sha256:xyz)

         Examples of valid docker-repository-references:
           "docker.io/myuser/myrepo"
           "docker.io/nginx"
           "docker.io/library/fedora"
           "localhost:5000/myrepository"

         Examples of invalid references:
           "docker.io/nginx:latest"
           "docker.io/myuser/myimage:v1.0"
           "docker.io/myuser/myimage@sha256:f48c4cc192f4c3c6a069cb5cca6d0a9e34d6076ba7c214fd0cc3ca60e0af76bb"

       **docker-archive:path[:docker-reference]
         more than one images were stored in a docker save-formatted file.

EXAMPLES

   Docker Transport
       To get the list of tags in the "fedora" repository from  the  docker.io  registry  (the  repository  name
       expands to "library/fedora" per docker transport canonical form):

       $ skopeo list-tags docker://docker.io/fedora
       {
           "Repository": "docker.io/library/fedora",
           "Tags": [
               "20",
               "21",
               "22",
               "23",
               "24",
               "25",
               "26-modular",
               "26",
               "27",
               "28",
               "29",
               "30",
               "31",
               "32",
               "branched",
               "heisenbug",
               "latest",
               "modular",
               "rawhide"
           ]
       }

       To list the tags in a local host docker/distribution registry on port 5000, in this case for the "fedora"
       repository:

       $ skopeo list-tags docker://localhost:5000/fedora
       {
           "Repository": "localhost:5000/fedora",
           "Tags": [
               "latest",
               "30",
               "31"
           ]
       }

   Docker-archive Transport
       To list the tags in a local docker-archive file:

       $ skopeo list-tags docker-archive:/tmp/busybox.tar.gz
       {
           "Tags": [
               "busybox:1.28.3"
           ]
       }

       Also supports more than one tags in an archive:

       $ skopeo list-tags docker-archive:/tmp/docker-two-images.tar.gz
       {
           "Tags": [
               "example.com/empty:latest",
               "example.com/empty/but:different"
           ]
       }

       Will include a source-index entry for each untagged image:

       $ skopeo list-tags docker-archive:/tmp/four-tags-with-an-untag.tar
       {
           "Tags": [
               "image1:tag1",
               "image2:tag2",
               "@2",
               "image4:tag4"
           ]
       }
