# [SYNOPSIS](#SYNOPSIS)

**docker image tag SOURCE\_IMAGE\[:TAG] TARGET\_IMAGE\[:TAG]**

# [DESCRIPTION](#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 ':'.

# [OPTIONS](#OPTIONS)

**NAME**  
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  
**registry-1.docker.io** 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.

**TAG**  
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  
characters.

# [EXAMPLES](#EXAMPLES)

# [Tagging an image referenced by ID](#Tagging_an_image_referenced_by_ID)

To tag a local image with ID "0e5574283393" into the "fedora" repository with "version1.0":

```
docker image tag 0e5574283393 fedora/httpd:version1.0
```

To tag a local image with name "httpd" into the "fedora" repository with "version1.0":

```
docker image tag httpd fedora/httpd:version1.0
```

Note that since the tag name is not specified, the alias is created for an existing local version **httpd:latest**.

# [Tagging an image referenced by Name and Tag](#Tagging_an_image_referenced_by_Name_and_Tag)

To tag a local image with name "httpd" and tag "test" into the "fedora" repository with "version1.0.test":

```

# [Tagging an image for a private repository](#Tagging_an_image_for_a_private_repository)

Before pushing an image to a private registry and not the central Docker registry you must tag it with the registry hostname and port (if needed).
