The sample deploys a VPC with public and private subnets, optional NAT gateway support, an EKS cluster, an optional node group, and a bastion host for secure cluster access.\n\n## What this project builds\n\n- AWS VPC with a configurable CIDR block\n- Public and private subnets across multiple availability zones\n- Internet Gateway and public route table\n- Optional NAT gateway deployment for private subnet internet access\n- EKS cluster with configurable endpoint access\n- Optional EKS managed node group or EKS auto mode\n- Bastion host with SSH access\n- Security groups for EKS control plane, worker nodes, and bastion\n- Cleanup helper to remove Network Load Balancers during destroy\n\n## Repository layout\n\n- `main.tf` - provider, backend and core configuration\n- `variables.tf` - variable definitions and defaults\n- `local.tf` - computed locals and creation conditions\n- `vpc.tf` - VPC and subnets\n- `igw.tf` - Internet Gateway\n- `nat.tf` - NAT Gateway and Elastic IP\n- `routes.tf` - route tables and associations\n- `sg.tf` - security groups for EKS and bastion\n- `eks.tf` - EKS cluster and access entry\n- `nodegroup.tf` - EKS managed node group\n- `outputs.tf` - exported output values\n- `cleanup.tf` - destroy-time cleanup for NLBs\n- `install-tools.sh` - installation script for ingress and Rancher\n- `setup-tools.sh` - Terraform install helper for Ubuntu\n- `environments/dev/terraform.tfvars` - development variables\n- `environments/prod/terraform.tfvars` - production variables\n- `.gitignore`\n- `README.md`\n\n## Prerequisites\n\n- Terraform 1.3 or later\n- AWS CLI 2 or later\n- AWS credentials configured locally\n- IAM roles already created for EKS cluster, node group, and bastion host\n- S3 backend bucket and DynamoDB lock table available for Terraform state\n\n## Configuration\n\nThe project uses `variables.tf` for defaults and environment files under `environments/` for deployment settings.\n\nUse one of the provided variable files:\n\n```bash\nterraform apply -var-file=environments/dev/terraform.tfvars\nterraform apply -var-file=environments/prod/terraform.tfvars\n```\n\nYou can also override individual values at runtime:\n\n```bash\nterraform apply -var=\"enable_nat_gateway=false\"\n```\n\n## Deployment\n\nInitialize Terraform and apply the configuration:\n\n```bash\nterraform init\nterraform validate\nterraform plan -var-file=environments/dev/terraform.tfvars\nterraform apply -var-file=environments/dev/terraform.tfvars\n```\n\nIf you change backend settings or move environments, update the backend configuration and re-run `terraform init`.\n\n## Destroy\n\nDestroy the deployed infrastructure when it is no longer needed:\n\n```bash\nterraform destroy -var-file=environments/dev/terraform.tfvars\n```\n\n## Post-deployment\n\nThe `install-tools.sh` script can be used after cluster provisioning to install ingress-nginx and Rancher. The `setup-tools.sh` script installs Terraform on Ubuntu.\n\n## Notes\n\n- The sample backend is configured for S3 with DynamoDB locking.\n- `enable_nat_gateway` controls whether NAT gateway resources are created.\n- `single_nat_gateway` controls whether one NAT gateway is shared across AZs or one per AZ.\n- `enable_eks_auto_mode` enables EKS auto mode and disables the managed node group.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbel7phegor%2Ftemplates-terraform","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbel7phegor%2Ftemplates-terraform","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbel7phegor%2Ftemplates-terraform/lists"}
