GCP-Terraform-Test

Terraform Webserver Load Balancer Deployment :

Pre-requisite:

- Terraform v1.1.9
- GCP (with credentials)

1. Clone the repo for setup GCP Load Balancer.

   git clone https://github.com/Vasanth3g/GCP-Terraform-Test.git

2. Download the credentials from GCP like below.

   {
     "type": "service_account",
     "project_id": "my-project",
     "private_key_id": "5a230d**********",
     "private_key": "-----BEGIN PRIVATE KEY----- ********   END PRIVATE KEY-----\n",
     "client_email": "*******@developer.gserviceaccount.com",
     "client_id": "1050***********",
     "auth_uri": "https://accounts.google.com/o/oauth2/auth",
     "token_uri": "https://oauth2.googleapis.com/token",
     "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
     "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/824080028473-compute%40developer.gserviceaccount.com"
   }
   

3. Replace the credentials file into auth directory.

   cp <file> auth/<file>

4. Below parameters needs to be change for your project:

   • Replace wherever project name and region on terraform files with respect to your account.
   • network parameter need to change as per your project on network-firewall.tf
   • instance groups under group paramter also need to change as per your project on gcp_lb.tf

5. Initiate the teraform configuration without errors.

   terraform init

6. Plan the teraform without errors.

   terraform plan

7. Above 5 & 6 th steps compiled then execute below step to apply resources in GCP.

   terraform apply --auto-approve

8. After applied resources, wait for around 10 min to setup all the webserver configs.

9. Run below command to get load balancer public IP like below :

       vasanthm@Vasanths-MacBook-Air GCP % terraform show | grep ip_address
       ip_address            = "*.*.*.*"
