Deployment of GCP resources through Terraform with GitHub Actions CI/CD Workflow

The Google Cloud resources can be deployed through Terraform (IaC) with CI/CD pipeline to be maintained through GitHub Actions. In this blog post, we’ll explore how to deploy GKE cluster through Terraform with GitHub Actions CI/CD.

For deployment of GCP resources through GitHub Actions terraform workflow, you can use Terraform cloud as backend like as the following.

terraform {

cloud {

organization = “<your_terraform_cloud_org>”

workspaces {

name = “<workspace_name>”

}

}

}

Then, specify the .tfvars file variables in the terraform cloud variables section. You can declare the sensitive values for resource variables as applicable.
