This repository contains Terraform code for infrastructure resource deployment on Google Public Cloud.

Below prerequisites must be fulfilled for successfull execution of code.

Resources in this repository are meant for use with Terraform 1.3.6 (Check the version using terraform version). If you don't have the compatible version, download it from official Terraform repository. See Installation-Guide on how to install Terraform.

• gcloud sdk >= 414.0.0
• Terraform >= 1.3.6
• [terraform-provider-google] plugin = 4.52.0
• [terraform-provider-google-beta] plugin = 4.52.0

In order to execute these templates you must have a Service Account with the following roles. Access can be more fine-grained to follow Principle of least privilege (PoLP).

• roles/resourcemanager.projectOwner on all the projects where you want to house your resources using service account's email.
• roles/storage.admin on the project housing terraform state files.

In order to use the services, required APIs must be enabled before resource deployment. Enable the APIs using below mentioned gcloud command.

gcloud services enable servicenetworking.googleapis.com \
    cloudresourcemanager.googleapis.com \
    compute.googleapis.com \
    iam.googleapis.com

To use a remote backend, create a GCS Bucket and set the versioning. Use below gcloud commands.

gcloud config set project PROJECT_ID
gsutil mb -c standard -l eu gs://bucket-name
gsutil versioning set on gs://bucket-name

For multiple environment provisioning, use different tfstate files in backend. To execute the Terraform code, go to command prompt and then run the following commands:

• [Required] terraform init
• [Optional] terraform validate
• [Optional] terraform fmt
• [Optional] terraform plan
• [Required] terraform apply -auto-approve

Note: See Terraform-Guide to get real-quick overview of Terraform.
