AWS Fargate is a serverless compute engine for containers that works with both Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS). In this guide, we’ll use Terraform to deploy an EKS cluster with Fargate compute and expose a microservice using an AWS Load Balancer.
Prerequisites:
- AWS CLI configured
- Terraform installed
- kubectl installed
Terraform Configuration:
Create a `main.tf` file with the following content:
provider "aws" {
region = "us-west-2"
}
module "eks" {
source = "terraform-aws-modules/eks/aws"
cluster_name = "fargate-cluster"
cluster_version = "1.27"
subnets = ["subnet-123456", "subnet-789012"]
vpc_id = "vpc-123456"
fargate_profiles = {
default = {
name = "fp-default"
selectors = [
{ namespace = "default" }
]
}
}
}
resource "aws_eks_addon" "example" {
cluster_name = module.eks.cluster_id
addon_name = "vpc-cni"
}
output "cluster_endpoint" {
value = module.eks.cluster_endpoint
}
Deploy the Cluster:
Run the following commands:
terraform init terraform plan terraform apply -auto-approve
Configure kubectl:
aws eks --region us-west-2 update-kubeconfig --name fargate-cluster kubectl get nodes
Expose a Microservice:
Deploy a sample app:
kubectl create deployment nginx --image=nginx kubectl expose deployment nginx --port=80 --type=LoadBalancer
Verify the Service:
kubectl get svc
You Should Know:
- AWS Fargate Pricing: Pay only for vCPU and memory used.
- Terraform Best Practices: Use remote state (S3 backend).
- Kubernetes Networking: Ensure VPC CNI addon is installed.
- Security: Apply IAM roles for least privilege access.
Expected Output:
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE nginx LoadBalancer 10.100.XX.XXX a1234567890abcdef1234567890abcdef-123456789.us-west-2.elb.amazonaws.com 80:32456/TCP 2m
What Undercode Say:
AWS Fargate simplifies Kubernetes management by removing node provisioning. Terraform ensures reproducible infrastructure. Always monitor costs and permissions when using serverless EKS.
Prediction:
As serverless Kubernetes adoption grows, expect tighter integration between Fargate, EKS, and DevOps tools like Terraform and GitHub Actions.
