## The web proctype
Like Heroku, we handle the `web` proctype differently from others. The `web` proctype is the only proctype that will invoke custom checks as defined by a CHECKS file. It is also the only proctype that will be launched in a container that is either proxied via nginx or bound to an external port.
## Image tagging
The dokku tag plugin allows you to add docker image tags to the currently deployed app image for versioning and subsequent deployment.
```
tag:add <app> <tag> Add tag to latest running app image
tag:deploy <app> <tag> Deploy tagged app image
tag:list <app> List all app image tags
tag:rm <app> <tag> Remove app image tag
```
Example:
```
root@dokku:~# dokku tag:list node-js-app
=====> Image tags for dokku/node-js-app
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
dokku/node-js-app latest 936a42f25901 About a minute ago 1.025 GB
