Deploy EKS CLuster with Fargate using Terraform

Prerequisites:

• Terraform installed
• AWS Account and AWS cli installed
• Kubectl installed. Follow this url for installation guide https://docs.aws.amazon.com/eks/latest/userguide/install-kubectl.html

Note

• This cluster based on the current configuration will be created in the us-east-1 regiona and is setup to wotk only with fargate
• Rerun terraform apply again if you receive Error: creating EC2 VPC: RequestError: send request failed │ caused by: Post "https://ec2.us-east-1.amazonaws.com/": read tcp 192.168.1.71:53727->209.54.181.193:443: wsarecv: An existing connection was forcibly closed by the remote host. and it should deploy the resources
• The deployment takes over 15 minutes

Resources Created

• VPC and all networking components
• EKS cluster
• aws load balancer controller for ingress
• Fargate profiles for application, aws-load-balancer-controller and Kube-system namespaces

Deployment Steps

1. terraform init
2. terraform fmt
3. terraform validate
4. terraform plan
5. terraform apply --auto-appprove

steps after succesful deployment of cluster with terraform

• After you provision the EKS with terraform, you would need to update your Kubernetes context to access the cluster with the following command - aws eks update-kubeconfig --name name-of-cluster --region region-where-cluster-is-deployed

• To patch coredns to run on fargate nodes, run the command below

---

kubectl patch deployment coredns
-n kube-system
--type json
-p='[{"op": "remove", "path": "/spec/template/metadata/annotations/eks.amazonaws.com~1compute-type"}]'
