• This repository will provision BIG-IP VE (Pay as you Grow), Consul & NGINX servers in AWS

You can check out a recording of this demo here

• Clone the repository
• Change directory

cd f5-terraform-consul-sd-webinar/terraform/

• Run terraform plan. terraform apply
• This will create BIG-IP, consul, NGINX instances on AWS
• Next we need to download and load AS3 rpm into BIG-IP, for AS3 documentation and download please refer to https://github.com/F5Networks/f5-appsvcs-extension
• Once the rpm is installed on BIG-IP change the directory using cd f5-terraform-consul-sd-webinar/as3
• Do terraform plan & apply, this will deploy the AS3 declarative JSON for service discovery on BIG-IP. It will use as3.tf file. You can either edit the example terraform.tfvars.example file in that directory to pass the necessary variables to terraform, or enter them manually via the CLI, copying the format of the values in the file.
• Now you have Virtual IP and Pool information already configured on BIG-IP in partition defined in the consul.json file.

• You can access backend applications using http://VIP_IP:8080 where VIP_IP is the Elastic IP which maps to BIG-IP Private VIP_IP.
• The NGINX servers are already in Auto scale group with consul agents running and sending all information to Consul server.
• Use case is when you destroy or bring down one of the NGINX server, BIG-IP AS3 will poll the consul server and update the pool members automatically
• So as the NGINX servers are going up and down the BIG-IP Pool members are updated automatically without manual intervention.

Folder as3 has three files, main.tf, nginx.json and variables.tf, main.tf is used to provision nginx.json template to BIG-IP once its ready. Please download the AS3 rpm module from https://github.com/F5Networks/f5-appsvcs-extension before doing terraform apply.

consul.sh is used to install consul f5.tpl is used to change the admin password. nginx.sh is used to install consul agent on nginx servers

• This folder has tf files for creating instances for consul, f5, iam policy, nginx servers with autoscale group.
• main.tf refres to what region is used on aws.
• ssh.tf is used to create the key pairs.
• vpc.tf is used to create a new vpc called f5.vpc and also to define the aws security groups.
• outputs.tf is used to output and display F5 BIG-IP management IP and F5 BIG-IP dynamic Password
• To login into F5 BIG-IP using GUI F5_IP displayed, for example use https://F5_IP:8443 and Passsword as value of F5_Password

• BIG-IP image used is 14.1 version
• AS3 rpm used is 3.7.0 version
