Automating BIG-IP with Terraform¶

Follow this script to demonstrate creation of Pools and Virtual Servers using Terraform plans.

Task – Imperative - Create VS, Pool and Members using playbook variables¶

From Firefox browser explore BIG-IP GUI Local Traffic -> Network Map to confirm app110 virtual servers does not exist

From VScode explorer click on imparative/main.tf to examine the plan

terraform {
  required_providers {
    bigip = {
       source = "F5Networks/bigip"
     }
   }
 }

 provider "bigip" {
     address = var.address
     username = var.username
     password = var.password
 }

 resource "bigip_ltm_monitor" "monitor" {
   name     = "/Common/app100_monitor"
   parent   = "/Common/http"
   send     = "GET /\r\n"
   timeout  = "300"
   interval = "3"
 }

 resource "bigip_ltm_node" "node" {
   name    = "/Common/10.1.20.5"
   address = "10.1.20.5"
 }

 resource "bigip_ltm_pool" "pool" {
   name                = "/Common/app100_pool"
   load_balancing_mode = "round-robin"
   monitors            = ["/Common/app100_monitor"]
   allow_snat          = "yes"
   allow_nat           = "yes"
   depends_on = [bigip_ltm_monitor.monitor]
 }

 resource "bigip_ltm_pool_attachment" "attach_node" {
   pool = "/Common/app100_pool"
   node = "/Common/10.1.20.5:80"
   depends_on = [bigip_ltm_pool.pool, bigip_ltm_node.node]
 }

 resource "bigip_ltm_virtual_server" "http" {
   pool = "/Common/app100_pool"
   name = "/Common/app100_vs"
   destination = "10.1.10.100"
   port = 80
   source_address_translation = "automap"
   depends_on = [bigip_ltm_pool.pool]
 }

From VScode terminal cd to hashicorp demo directory
- Type cd ~/f5channel-demos/hashicorp/imperative/
Run the terraform init
- Type terraform init
Run the terraform plan
- Type terraform plan
Run the terraform apply
- Type terraform apply -auto-approve
From Firefox browser explore BIG-IP GUI Local Traffic -> Network Map to confirm app100 virtual server now exists
Run the terraform destroy
- Type terraform destroy -auto-approve
From Firefox browser refresh BIG-IP GUI Local Traffic -> Network Map to confirm app100 virtual server is removed

Task – Declarative - Create VS, Pool and Members using AS3¶

From VScode explorer click on declarative/main.tf to examine the plan

terraform {
  required_providers {
    bigip = {
      source = "F5Networks/bigip"
    }
  }
}

provider "bigip" {
    address = var.address
    username = var.username
    password = var.password
}

resource "bigip_as3" "app101" {
  as3_json = "${file("app101.json")}"
}

From VScode explorer click on declarative/app101.json to examine the AS3 template
