Deploying a FAST Application

Deploy using the GUI

From the BIG-IP, Launch FAST from iApps > Application Services > Applications LX. You will be presented with 4 tabs, select Deploy. Under Available Templates, expand the section containing the template to deploy.

For this example we are using examples/simple_udp. Fields noted with an asterisk * are required.

1. Enter a Tenant Name. The tenant is the high-level grouping in an AS3 declaration. FAST deploys all configuration for a given tenant in a BIG-IP partition of the same name.
2. Enter an Application Name. The application is the low-level grouping in an AS3 declaration. FAST deploys all configuration for a given application in a BIG-IP folder within the tenant partition.
3. Enter the virtual_port.
4. Enter the virtual_address.
5. Enter the server_port.
6. Enter a server_address for each server. This field is not required.

See the image below for example field entries.


Clicking on the View Rendered button displays a sample of the rendered output of the template.


Clicking on Submit will start a deployment job. The current status of the job can be found on the Deploy Log tab.

Deploy using the FAST API

FAST also exposes a REST API for programmability and automation. The basics of working with REST APIs is assumed and will not be covered in this document.

The same examples/simple_udp deployment from the above GUI example can be done via a POST to the mgmt/shared/fast/applications endpoint. Using cURL to do this would look like:

curl -sku <BIG-IP username>:<BIG-IP password> -H "Content-Type: application/json" -X POST https::/<IP address of BIG-IP>/mgmt/shared/fast/applications -d " \
{ \
   "name": "examples/simple_http", \
   "parameters": { \
     "tenant_name": "Tenant1", \
     "application_name": "Application1", \
     "virtual_port": 443, \
     "virtual_address":, \
     "server_port": 80, \
     "server_addresses": [""] \
   } \

This job is asynchronous and a successful response indicates that the task was submitted, not that it completed successfully. The response payload contains an id that can be used to query mgmt/shared/fast/tasks/<task ID> for the current status of the task.

Submitting another task while a previous one is still in progress can result in an error from AS3. It is recommended to either wait on the result of a previous deployment task before submitting another one or to enable Burst Handling for AS3.

A reference for the FAST REST API can be found in Appendix A: API Reference.
