     4  # NAME
     5  docker-tag - Tag an image into a repository
     6  
     7  # SYNOPSIS
     8  **docker tag**
     9  [**-f**|**--force**[=*false*]]
    10  IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG]
    11  
    12  # DESCRIPTION
    13  This will give a new alias to an image in the repository. This refers to the
    14  entire image name including the optional TAG after the ':'. 
    15  
    16  # "OPTIONS"
    17  **-f**, **--force**=*true*|*false*
    18     When set to true, force the alias. The default is *false*.
    19  
    20  **REGISTRYHOST**
    21     The hostname of the registry if required. This may also include the port
    22  separated by a ':'
    23  
    24  **USERNAME**
    25     The username or other qualifying identifier for the image.
    26  
    27  **NAME**
    28     The image name.
    29  
    30  **TAG**
    31     The tag you are assigning to the image.  Though this is arbitrary it is
    32  recommended to be used for a version to distinguish images with the same name.
    33  Note that here TAG is a part of the overall name or "tag".
    34  
    35  # OPTIONS
    36  **-f**, **--force**=*true*|*false*
    37     Force. The default is *false*.
    38  
    39  # EXAMPLES
    40  
    41  ## Giving an image a new alias
    42  
    43  Here is an example of aliasing an image (e.g., 0e5574283393) as "httpd" and 
    44  tagging it into the "fedora" repository with "version1.0":
    45  
    46      docker tag 0e5574283393 fedora/httpd:version1.0
    47  
    48  ## Tagging an image for a private repository
    49  
    50  To push an image to an private registry and not the central Docker
    51  registry you must tag it with the registry hostname and port (if needed).
    52  
    53      docker tag 0e5574283393 myregistryhost:5000/fedora/httpd:version1.0
