NAME

       skopeo-list-tags - List image names in a transport-specific collection of images.

SYNOPSIS

       skopeo list-tags [options] source-image

       Return a list of tags from source-image in a registry or a local docker-archive file.

       source-image  name  of  the  repository  to retrieve a tag listing from or a local docker-
       archive file.

OPTIONS

       --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.

       --help, -h

       Print usage statement

       --no-creds

       Access the registry anonymously.

       --registry-token Bearer token

       Bearer token for accessing 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 registry.conf setting.

       --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"
                  ]
              }
