# NAME
|
||
|
|
docker-tag - Tag an image into a repository
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
**docker tag**
|
||
|
|
[**-f**|**--force**[=*false*]]
|
||
|
|
[**--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"
|
||
|
|
**-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 distinguish images with the same name.
|
||
|
|
Note that here TAG is a part of the overall name or "tag".
|
||
|
|
|
||
|
|
# OPTIONS
|
||
|
|
**-f**, **--force**=*true*|*false*
|
||
|
|
Force. The default is *false*.
|
||
|
|
|
||
|
|
# 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
