docker-image-tag - Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE




Assigns a new alias to an image in a registry. An alias refers to the entire image name including the optional TAG after the ':'.


The image name which is made up of slash-separated name components,
optionally prefixed by a registry hostname. The hostname must comply with
standard DNS rules, but may not contain underscores. If a hostname is
present, it may optionally be followed by a port number in the format
:8080. If not present, the command uses Docker's public registry located at by default. Name components may contain lowercase
letters, digits and separators. A separator is defined as a period, one or
two underscores, or one or more dashes. A name component may not start or end
with a separator.

The tag assigned to the image to version and distinguish images with the same
name. The tag name must be valid ASCII and may contain lowercase and
uppercase letters, digits, underscores, periods and hyphens. A tag name
may not start with a period or a hyphen and may contain a maximum of 128
