# Triggers
|
|
|
|
Triggers are integrations that you can use in other systems to fire off functions in Fn.
|
|
|
|
## OpenStack

|
|
|
### Requirements
|
|
|
|
1. OpenStack or DevStack environment.

|
|
* OS: Ubuntu 16.04 LTS or newer
|
|
* Kernel: 4.7 or newer with overlay2 or aufs module
|
|
* Docker: 1.12 or newer

|
2. [Picasso](https://github.com/openstack/picasso) - Picasso provides an OpenStack API and Keystone authentication layer on top of Fn.
