NAME
docker-tag - Tag an image in the repository
SYNOPSIS
docker tag [-f|--force[=false] IMAGE [REGISTRYHOST/][USERNAME/]NAME[:TAG]
DESCRIPTION
This will rename 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 tag name. 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
Tagging an image
Here is an example of renaming 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
