docker-tag - Tag an image in the repository
docker tag [-f|--force[=false] IMAGE [REGISTRYHOST/][USERNAME/]NAME[:TAG]
This will tag an image in the repository.
-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.
Here is an example of tagging an image with the tag version1.0 :
docker tag 0e5574283393 fedora/httpd:version1.0
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
