# NAME
docker-tag - Tag an image in the repository
# SYNOPSIS
**docker tag** [**-f**|**--force**[=*false*]
IMAGE [REGISTRYHOST/][USERNAME/]NAME[:TAG]
# DESCRIPTION
This will give a new alias to an image in the repository. This refers to the
entire image name including the optional TAG after the ':'.
# "OPTIONS"
**-f**, **--force**=*true*|*false*
When set to true, force the alias. The default is *false*.
**REGISTRYHOST**
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 disinguish images with the same name.
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 an 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
# HISTORY
