The following is the Terraform configuration file used with Google Cloud. The file has .tf<\/code> extension i.e. main.tf <\/code>.<\/p>\n\n\n\nterraform {\n required_providers {\n google = {\n source = \"hashicorp\/google\"\n version = \"3.5.0\"\n }\n }\n}\n\nprovider \"google\" {\n credentials = file(\"<NAME>.json\")\n\n project = \"<PROJECT_ID>\"\n region = \"us-central1\"\n zone = \"us-central1-c\"\n}\n\nresource \"google_compute_network\" \"vpc_network\" {\n name = \"terraform-network\"\n}<\/code><\/pre>\n\n\n\n<NAME<\/code>> should be replaced with the path to the service account key file you obtained, and <PROJECT_ID<\/code>> should be replaced with the ID of your project.<\/p>\n\n\n\nTerraform parameters, including the essential providers Terraform will use to provision your infrastructure, are contained in the terraform {}<\/code> block.<\/p>\n\n\n\nCreating VM instance in Cloud Cloud using Terraform<\/h3>\n\n\n\n
The following are prerequisites in order to create an instance using Terraform.<\/p>\n\n\n\n
\n- You’ll need a Google Cloud Platform account to get started. Create a Google Cloud Platform<\/a> account if you don’t already have one. This tutorial can be performed entirely with the GCP free tier’s services.<\/li>\n\n\n\n
- Locally installed Terraform version 0.15.3+.<\/li>\n<\/ol>\n\n\n\n
GCP Setup<\/h3>\n\n\n\n
To enable Terraform to provision your infrastructure, build or edit the following resources after creating your GCP account.<\/p>\n\n\n\n
a) GCP Project<\/strong><\/p>\n\n\n\nResources are organized into projects by GCP. Create one in the GCP<\/a> console right now and save the project ID. In the cloud resource manager, you may see a list of your projects.<\/p>\n\n\n\n![\"\"](\"https:\/\/computingforgeeks.com\/wp-content\/uploads\/2024\/11\/terraform-gcp-create-project-01.webp\" "\\"\\"")
<\/figure>\n<\/div>\n\n\nb) Google Compute Engine<\/strong><\/p>\n\n\n\nIn the GCP console, enable Google Compute Engine for your project. To follow this lesson, make sure you select the project you’ll be using and click the “Enable” option.<\/p>\n\n\n
\n![\"\"](\"https:\/\/computingforgeeks.com\/wp-content\/uploads\/2024\/11\/terraform-gcp-enable-compute-02.webp\" "\\"\\"")
<\/figure>\n<\/div>\n\n\nc) GCP service account key<\/strong><\/p>\n\n\n\nTo allow Terraform to access your GCP account, create a service account key<\/a>. Use the following procedures when creating the key:<\/p>\n\n\n\n![\"\"](\"https:\/\/computingforgeeks.com\/wp-content\/uploads\/2024\/11\/terraform-gcp-choose-project-03.webp\" "\\"\\"")
<\/figure>\n<\/div>\n\n\nChoose the project you made in the preceding stage.<\/p>\n\n\n\n
Select “Create Service Account<\/strong>“.<\/p>\n\n\n\n![\"\"](\"https:\/\/computingforgeeks.com\/wp-content\/uploads\/2024\/11\/terraform-gcp-create-service-account-04-1024x330.webp\" "\\"\\"")

<\/figure>\n<\/div>\n\n\nClick “Done<\/strong>” instead of providing more users access. Download your service account key after you’ve created your service account:<\/p>\n\n\n\nChoose your service account from the list.<\/p>\n\n\n\n![\"\"](\"https:\/\/computingforgeeks.com\/wp-content\/uploads\/2024\/11\/terraform-gcp-manage-keys-07-1024x660.png\" "\\"\\"")

<\/figure>\n\n\n\nTo create the key and store the key file to your PC, click “Create<\/strong>.”<\/p>\n\n\n\nDeploy VM Instance on Google Cloud<\/h3>\n\n\n\n
Create Terraform working directory and change to it:<\/p>\n\n\n\n
mkdir terraform-project\ncd terraform-project<\/code><\/pre>\n\n\n\nCreate a main.tf<\/code> file for the instance.<\/p>\n\n\n\nvim main.tf<\/code><\/pre>\n\n\n\nAdd the content below to the file above:<\/p>\n\n\n\n
