NAME

       docker-tag - Tag an image into a repository

SYNOPSIS

       docker tag [--help] IMAGE[:TAG] [REGISTRY_HOST/][USERNAME/]NAME[: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 ':'.

       If you do not specify a REGISTRY_HOST, the command uses Docker's public registry located
       at registry-1.docker.io by default.

OPTIONS

       --help
          Print usage statement.

       REGISTRY_HOST
          The hostname of the registry if required. This may also include the port separated by a
       ':'

       USERNAME
          The username or other qualifying identifier for the image.

       NAME
          The image name.

       TAG
          The tag you are assigning to the image.  Though this is arbitrary it is recommended to
       be used for a version to distinguish images with the same name.  Also, for consistency
       tags should only include a-z0-9-_. .  Note that here TAG is a part of the overall name or
       "tag".

EXAMPLES

Giving an image a new alias

       Here is an example of aliasing an image (e.g., 0e5574283393) as "httpd" and tagging it
       into the "fedora" repository with "version1.0":

              docker tag 0e5574283393 fedora/httpd:version1.0

Tagging an image for a private repository

       To push 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 tag 0e5574283393 myregistryhost:5000/fedora/httpd:version1.0
