Automation with Terraform, Ansible on Google Cloud Platform (GCP)

Terraform and Anisble DevOps deployment
Deploying Google GCP Virtual Network, Subnet, 2 GCP Instance with Google Load Balancer by Terraform. The Ansible with Terraform will install PHP, NGNIX and REDIS.

Pre-requisite

Install Terraform on the local machine https://www.terraform.io/downloads.html
Create an free Google Cloud platform account (GCP) at URL https://console.cloud.google.com/
In the Google Cloud platform GCP, go to IAM and Admin , Create a Sample Project and obtain the project-id
On your local machine, install Google Cloud SDK (recommended for debugging purpose) URL https://cloud.google.com/sdk
Recommended to install Git Bash
How to install Google Cloud SDK - https://cloud.google.com/sdk/docs/downloads-versioned-archives

In the Cloud Console, go to the Create service account key page. Go to the Create Service Account Key page
From the Service account list, select New service account. In the Service account name field, enter a name. From the Role list, select Project > Owner.

Use the following link - https://cloud.google.com/docs/authentication/production

cd terraform-ansible-gcp

Update the terraform.tfvars file. Update the 'project_id' with the GCP Project ID
Perform following commands to authenticate GCP.
Recommend to use us-east-1 region and us-east-1b as zone.
Select the project and the email address.

glcoud init

terraform init
terraform plan
terraform apply

The template is using Terraform with Ansible
The Google Cloud Platform GCP resource type is used as provider.
There are local variable and also we are using data source, check the main.tf (google_project)
The data source allow us to check if not exisit, or not.
The terraform templates creates 2 managed instance groups that can use autoscaling.
The port 80 and 443 are open through the Google Load Balancer
The module for PHP, Redis, Google Load Balancer
The Ansible Playbook will install the PHP and NGNIX in one GCP Compute Engine
The Anisble Playbook will install Redis on another GCP Compute Engine.
Nginx is exposed to Internet via google load balancer.
The Ansible Playbook is triggered by Terraform using cloud-config
The Anisble Playbook utilize Google Cloud Storage
There are task in the Ansible playbook and marked with tags (Intall PHP, Install Apache, Start NGNIX, REDIS)
After login into the GCP Compute by SSH execute following commands to verify the PHP, NGNIX and redis installation by Ansible
On the PHP GCP Compute Engine

 php -v
 ngnix -v

redis-server --version
