NAME

       docker-image-tag - Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE

SYNOPSIS

       docker image tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

DESCRIPTION

       Assigns a new alias to an image in a registry. An alias refers to the entire image name
       including the optional TAG after the ':'.

OPTIONS

       NAME
          The image name which is made up of slash-separated name components,
          optionally prefixed by a registry hostname. The hostname must comply with
          standard DNS rules, but may not contain underscores. If a hostname is
          present, it may optionally be followed by a port number in the format
          :8080. If not present, the command uses Docker's public registry located at
          registry-1.docker.io by default. Name components may contain lowercase
          letters, digits and separators. A separator is defined as a period, one or
          two underscores, or one or more dashes. A name component may not start or end
          with a separator.

       TAG
          The tag assigned to the image to version and distinguish images with the same
          name. The tag name must be valid ASCII and may contain lowercase and
          uppercase letters, digits, underscores, periods and hyphens. A tag name
          may not start with a period or a hyphen and may contain a maximum of 128
          characters.

EXAMPLES

Tagging an image referenced by ID

       To tag a local image with ID "0e5574283393" into the "fedora" repository with
       "version1.0":

              docker image tag 0e5574283393 fedora/httpd:version1.0

Tagging an image referenced by Name

       To tag a local image with name "httpd" into the "fedora" repository with "version1.0":

              docker image tag httpd fedora/httpd:version1.0

       Note that since the tag name is not specified, the alias is created for an existing local
       version httpd:latest.

Tagging an image referenced by Name and Tag

       To tag a local image with name "httpd" and tag "test" into the "fedora" repository with
       "version1.0.test":

              docker image tag httpd:test fedora/httpd:version1.0.test

Tagging an image for a private repository

       Before pushing an image to a private registry and not the central Docker registry you must
       tag it with the registry hostname and port (if needed).

              docker image tag 0e5574283393 myregistryhost:5000/fedora/httpd:version1.0

OPTIONS

       -h, --help[=false]
           help for tag
