# Image Tagging

> New as of 0.4.0

The dokku tags plugin allows you to add docker image tags to the currently deployed app image for versioning and subsequent deployment.

```
tags <app>                                       List all app image tags
tags:create <app> <tag>                          Add tag to latest running app image
tags:deploy <app> <tag>                          Deploy tagged app image
tags:destroy <app> <tag>                         Remove app image tag
```

Example:

```
root@dokku:~# dokku tags node-js-app
=====> Image tags for dokku/node-js-app
