About F5 Application Services Templates

The F5 Application Services Templates extension, or FAST, provides a way to streamline deployment of applications on BIG-IP using templatized AS3 declarations.

AS3 applications deployed through FAST can be managed using FAST. FAST auto-generates web forms custom to your templates for creating and modifying applications, and provides visibility into what FAST applications are configured on your BIG-IP.

The extension comes with a base set of templates for common use cases such as TCP or HTTPS. New templates can be created to satisfy specific needs of any infrastructure.


See Install / Uninstall for installation instructions.


On BIG-IP versions prior to 14.0, the iApps LX framework must be enabled before the Configuration utility is visible. To do this, run the following command on the BIG-IP: touch /var/config/rest/iapps/enable. This command only needs to be run once (per BIG-IP system). This is not necessary with BIG-IP 14.0 and later.

Usage Quick Start

  1. The extension’s UI can be found by navigating to iApps > Application Services > Applications LX

  2. Click F5 Application Services Templates to start using FAST. There is a navigation menu at the top, and the initial tab displays a list of FAST applications on the BIG-IP, which will likely be empty on a fresh installation.

  3. To create an application, first click the FAST Templates tab to display a list of available templates that are ready to deploy.

  4. Click one of the template names, fill out the required fields, and then click Deploy.

  5. Upon submission, the page will redirect to the History tab, where there current status of the deploy action can be seen.

  6. After the deployment is successful, select to the Applications tab to see the deployed application. From here the application can be modified or deleted.


We strongly recommend not using both FAST AND iApp templates together as these templating solutions are incompatible with each other. Using both FAST and iApps is likely to create configuration and source-of-truth conflicts, resulting in an undesirable end-state.


Modifying FAST applications outside of FAST (e.g., via TMSH or with AS3 declarations) can result in those changes getting overwritten the next time FAST modifies the application. See Frequently Asked Questions (FAQ) for more information.
