AS3 Integration

Welcome to the F5 AS3 Integration Resources for Terraform.

You can use Terraform with AS3 for managing application-specific configurations on an F5 BIG-IP system. AS3 uses a declarative model, meaning you provide a JSON declaration rather than a set of imperative commands. The declaration represents the configuration which AS3 is responsible for creating on an F5 BIG-IP system. Terraform provides resources to configure AS3 declarative JSON on BIG-IP.

Prerequisites

To use AS3 Extensions with Terraform, ensure you meet the following requirements:

  • The BIG-IP system is running software version 12.1.x or newer
  • The BIG-IP system has AS3 Extension version 3.10 or newer installed
  • A BIG-IP system user account with the Administrator role

Example Usage

Example usage for json file

3
 resource "bigip_as3"  "as3-example1" {
     as3_json = "${file("example1.json")}"
 }
Example usage for json file with tenant filter

4
 resource "bigip_as3"  "as3-example1" {
     as3_json = "${file("example2.json")}"
     tenant_filter = "Sample_03"
 }

Argument Reference

  • as3_json - (Required) Path/Filename of Declarative AS3 JSON which is a json file used with builtin file function

  • tenant_filter - (Optional) If there are multiple tenants in a json this attribute helps you set a particular tenant to which you want to reflect the changes. Other tenants will not be created or modified.

  • as3_example1.json - Example AS3 Declarative JSON file with single tenant.

}

AS3 Installation

Use the following Terraform provisioner to download AS3 RPM from GitHub and install the RPM on BIG-IP:

resource "null_resource" "install_as3" {

  provisioner "local-exec" {

     command = "./install-as3-rpm.sh x.x.x.x xxxx:xxxx"

     }

}

You must pass BIG-IP and its credentials as an argument to the install script. This script is available in the examples section of AS3 in the Terraform GitHub repo.

Note

AS3 tenants are BIG-IP administrative partitions used to group configurations that support specific AS3 applications. An AS3 application may support a network-based business application or system. AS3 tenants can also include resources shared by applications in other tenants.
