BIG-IP Onboarding wtih DO (Declarative Onbarding)

In this section you will configure basic network configurations like NTP, DNS, and interface IP addresses.

1. Create bigip1.do.json json declaration

   • touch bigip1.do.json
   • use vscode to add the following code to bigip1.do.json

   {
    "$schema": "https://raw.githubusercontent.com/F5Networks/f5-declarative-onboarding/master/src/schema/latest/base.schema.json",
    "schemaVersion": "1.12.0",
    "class": "Device",
    "async": true,
    "label": "LTM declaration for declarative onboarding",
    "Common": {
        "class": "Tenant",
        "mySystem": {
            "class": "System",
            "hostname": "bigip1.f5demos.com",
            "cliInactivityTimeout": 1200,
            "consoleInactivityTimeout": 1200,
            "autoPhonehome": false
        },
        "myDns": {
            "class": "DNS",
            "nameServers": [
                "8.8.8.8",
                "8.8.4.4"
            ],
            "search": [
                "f5demos.com"
            ]
        },
        "myNtp": {
            "class": "NTP",
            "servers": [
               "0.pool.ntp.org",
                "1.pool.ntp.org",
                "2.pool.ntp.org"
            ],
            "timezone": "UTC"
        },
        "admin": {
            "class": "User",
            "userType": "regular",
            "password": "F5d3vops$",
            "shell": "bash"
        },
        "myProvisioning": {
            "class": "Provision",
            "ltm": "nominal",
            "asm": "nominal"
        },
        "internal": {
            "class": "VLAN",
            "tag": 4091,
            "interfaces": [{
                "name": "1.1",
                "tagged": false
            }]
        },
        "internal-self": {
            "class": "SelfIp",
            "address": "10.1.10.6/24",
            "vlan": "internal",
            "allowService": "default",
           "trafficGroup": "traffic-group-local-only"
        },
        "external": {
            "class": "VLAN",
            "tag": 4092,
            "interfaces": [{
                "name": "1.2",
                "tagged": false
            }]
        },
        "external-self": {
            "class": "SelfIp",
            "address": "10.1.20.6/24",
            "vlan": "external",
            "allowService": "none",
            "trafficGroup": "traffic-group-local-only"
        },
        "default": {
            "class": "Route",
            "gw": "10.1.20.1",
            "network": "default",
            "mtu": 1500
        },
        "dbvars": {
            "class": "DbVariables",
            "ui.advisory.enabled": true,
            "ui.advisory.color": "green",
            "ui.advisory.text": "BIG-IP1"
        }
    }
   }
   

2. Modify files to only deploy basic network configurations (NTP, DNS, VLANS and SELFIPs)

   • mv f5base.tf f5base.tfbkup
   • mv app1.tf app1.tfbkup
   • use vscode to modify main.tf with the following code to use bigip_do

   terraform {
   required_providers {
     bigip = {
       source = "F5Networks/bigip"
       version = "1.3.1"
     }
   }
   }
   
   provider "bigip" {
     address = "10.1.1.6"
     username = "admin"
     password = "F5d3vops$"
   }
   
   resource "bigip_do"  "bigip1" {
      do_json = "${file("bigip1.do.json")}"
      timeout = 15
   }
   

   • terraform plan
   • terraform apply -auto-approve

   Note

   The apply will most likely result with and error due to resource dependencies. If so, you may simply run terraform apply again. However I recommend you resolve the dependencies as hinted in the previous step to ensure consistency.

3. Confirm BIG-IP is now configured

   • Explore BIG-IP GUI Network -> SelfIP and Vlan settings are now configured
   

   Note

   Bonus lab - Create json declaration for bigip2 (10.1.1.7) given external 10.1.20.7 and internal 10.1.10.7 and apply plan.
