PROGRAM:
NAME
docker-tag - Tag an image into a repository
SYNOPSIS
docker tag [--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
--help
Print usage statement.
REGISTRY_HOST
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. Also, for consistency
tags should only include a-z0-9-_. . 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 a 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
