## Description

AWS EKS Kubernetes management for clusters, node groups, and workloads. Use when creating clusters, configuring IRSA, managing node groups, deploying applications, or integrating with AWS services.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# AWS EKS

Amazon Elastic Kubernetes Service (EKS) runs Kubernetes without installing and operating your own control plane. EKS manages the control plane and integrates with AWS services.

## Core Concepts

### Control Plane

Managed by AWS. Runs Kubernetes API server, etcd, and controllers across multiple AZs.

### Node Groups

| Type | Description |
|------|-------------|
| **Managed** | AWS manages provisioning, updates |
| **Self-managed** | You manage EC2 instances |
| **Fargate** | Serverless, per-pod compute |

### IRSA (IAM Roles for Service Accounts)

Associates Kubernetes service accounts with IAM roles for fine-grained AWS permissions.

### Add-ons

Operational software: CoreDNS, kube-proxy, VPC CNI, EBS CSI driver.

## Common Patterns

### Create a Cluster

**AWS CLI:**

```bash
# Create cluster role
aws iam create-role \
  --role-name eks-cluster-role \
  --assume-role-policy-document '{
    "Version": "2012-10-17",
    "Statement": [{
      "Effect": "Allow",
      "Principal": {"Service": "eks.amazonaws.com"},
      "Action": "sts:AssumeRole"
    }]
  }'

aws iam attach-role-policy \
  --role-name eks-cluster-role \
  --policy-arn arn:aws:iam::aws:policy/AmazonEKSClusterPolicy

# Create cluster
aws eks create-cluster \
  --name my-cluster \
  --role-arn arn:aws:iam::123456789012:role/eks-cluster-role \
  --resources-vpc-config subnetIds=subnet-12345678,subnet-87654321,securityGroupIds=sg-12345678

# Wait for cluster
aws eks wait cluster-active --name my-cluster

# Update kubeconfig
aws eks update-kubeconfig --name my-cluster --region us-east-1
```
