# GCP GKE Cluster Setup Using Terraform
[](https://github.com/mikaeelkhalid)
This repository contains Terraform configurations to set up a Google Kubernetes Engine (GKE) cluster on Google Cloud Platform (GCP) with various features and resources.
## File Structure
The repository is organized into multiple Terraform configuration files, each responsible for a specific GCP resource or functionality:
```
├── firewalls.tf # Firewall rules configuration
├── kubernetes.tf # GKE cluster configuration
├── nat.tf # NAT router and address configuration
├── node-pools.tf # GKE node pools configuration
├── provider.tf # Terraform provider and backend configuration
├── router.tf # GCP router configuration for the VPC
├── subnets.tf # Subnetworks configuration
├── variables.tf # Variables
└── vpc.tf # Virtual Private Cloud (VPC) configuration
```
Make sure to familiarize yourself with each file to understand the resources being created and their interdependencies.
## Resources Created
1. **Virtual Private Cloud (VPC)**: A named `main` VPC is set up.
2. **Subnetwork**: A private subnetwork within the `us-central1` region.
3. **Firewall Rule**: Allows SSH traffic (port 22) from any source.
4. **Google Kubernetes Engine (GKE) Cluster**: Configured to use the created VPC and subnetwork.
5. **Node Pools**: Two node pools, `general` and `spot`, are created within the GKE cluster.
6. **Router and NAT**: For routing traffic to and from the private subnetwork.
7. **Service Account**: A service account named `kubernetes` for the GKE cluster.
## Prerequisites
- [Terraform](https://www.terraform.io/downloads.html) installed.
- A [GCP account](https://console.cloud.google.com/) and a project set up.
- Properly [configured](https://cloud.google.com/sdk/docs/initializing) Google Cloud SDK.
## Getting Started
1. **Clone the repository**:
```sh
git clone https://github.com/mikaeelkhalid/gcp-gke-cluster-terraform.git
```
2. **Initialize the Terraform working directory**:
```sh
terraform init
```
3. **Apply the Terraform configuration**:
```sh
terraform apply
```
This will show you what changes will be applied. If everything looks good, approve the changes to begin provisioning resources.
4. Once you're done, remember to **destroy the resources** to avoid unwanted costs:
```sh
terraform destroy
```
## Notes
- Ensure that you've set the correct project ID in the `provider.tf` file.
- The `node-pools.tf` file configures both standard and preemptible (spot) node pools. Adjust the node count and machine type as per your requirements.
- Ensure that the Google Cloud Storage bucket defined in `terraform` backend block in `provider.tf` exists for storing the Terraform state.
## Contributing
Feel free to raise issues or pull requests if you'd like to improve the configurations or add more features.
