Eks Api

Amazon EKS is the most widely deployed managed Kubernetes in enterprise AWS environments — deeply integrated with IAM (IRSA for pod authentication), VPC networking, ALB (AWS Load Balancer Controller), EBS/EFS (persistent volumes), and CloudWatch (logging). For agents: create clusters, manage node groups (EC2 or Fargate), update add-ons (CoreDNS, kube-proxy, VPC-CNI), retrieve kubeconfig for kubectl access, and configure IRSA for pod-level AWS service auth. EKS Auto Mode (2024) provides full-node management for teams wanting less operational overhead. Confidence is docs-derived.

EKS API via boto3 (Python). eks.create_cluster(name, version, roleArn, resourcesVpcConfig={subnetIds, securityGroupIds}) creates cluster. eks.describe_cluster(name) retrieves status and endpoint. eks.create_nodegroup(clusterName, nodegroupName, scalingConfig={minSize,maxSize,desiredSize}, instanceTypes, nodeRole) creates node group. eks.update_nodegroup_config(clusterName, nodegroupName, scalingConfig) scales nodes. eks.create_addon(clusterName, addonName, addonVersion) installs add-on (vpc-cni, coredns, kube-proxy, aws-ebs-csi-driver). eksctl CLI: eksctl create cluster --name=my-cluster --region=us-east-1 for simplified cluster creation. Kubeconfig: aws eks update-kubeconfig --name=my-cluster or boto3 generate kubeconfig token.

IAM-based auth: SigV4 via boto3. IAM roles: eks:CreateCluster, eks:DescribeCluster, eks:CreateNodegroup, eks:UpdateNodegroupConfig. Cluster role: IAM role for EKS control plane. Node role: IAM role for EC2 worker nodes. IRSA: bind K8s ServiceAccount to IAM role via OIDC provider — enable pods to assume IAM roles without stored credentials. AWS auth ConfigMap: maps IAM users/roles to Kubernetes RBAC groups — update when adding new operators. Fargate profile: IAM role for Fargate pod execution.

Cluster creation: async — poll describe_cluster until ACTIVE (~15-20 minutes). Node group scaling: 2-5 minutes. EKS add-on update: async, rolling. IAM auth: EKS uses aws-iam-authenticator or AWS CLI token generation for kubectl — configure AWS credentials before kubectl commands. Cluster upgrade: upgrade control plane then node groups sequentially. EKS uptime at status.aws.amazon.com. Node group launch template: customize EC2 instances, bootstrap commands, kubelet config. EKS Auto Mode: manages node lifecycle automatically — less control but less ops burden.

docs.aws.amazon.com/eks covers cluster creation guide, node group management, IRSA setup, add-on documentation, and networking guide. Getting started: AWS free tier, eksctl create cluster — cluster ready in under 20 minutes. eksctl: brew install eksctl or curl-based install. boto3 eks client: pip install boto3. Terraform: aws_eks_cluster, aws_eks_node_group. Community via AWS re:Post and Stack Overflow (amazon-eks tag). Comprehensive documentation; eksctl greatly simplifies cluster management compared to raw API calls.
