## Prerequisites
### Installing AWS CLI
- https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html
- https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html
- https://docs.aws.amazon.com/cli/latest/userguide/cli-services-ec2-instances.html
- https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html
```
aws --version
aws configure help
```
### Installing kubectl

## EKS Cluster through Management Console
### Steps
- Create another IAM user with console and programmatic access
- Configure AWS CLI
```
aws iam list-users
```
### Get config
```
aws eks update-kubeconfig \
--region REGION \
--name CLUSTER_NAME
```
## Create EKS Cluster through EKSCTL
```
# Syntax
eksctl create cluster --name cluster-name \
--region region-name \
--version 1.23 \
--nodegroup-name test \
--node-type instance-type \
--node-volume-size \
--nodes-min 2 \
--nodes-max 2 \
--zones ,
# Example
eksctl create cluster --name demo --region=ap-south-1 --nodegroup-name demo --nodes 2 --nodes-min 1 --nodes-max 4 --node-volume-size 8
# Get list of clusters
eksctl get cluster --region ap-south-1
# Delete EKS Cluster through EKSCTL
eksctl delete cluster --name demo --region=ap-south-1
```
## Create Control Plane and Node Group seperately
```
# Create Cluster
eksctl create cluster --name=demo --region=ap-south-1 --without-nodegroup
# Get list of clusters
eksctl get cluster
# Delete the cluster
eksctl delete cluster demo --region=ap-south-1
```
### Create Node Group with IAM policies to access ALB, DNS, ECR, ASG etc. You should first create a keypair(RSA, .pem) to be used for SSH access to the worker nodes
```
# Help
eksctl create nodegroup --help
# Create NodeGroup with IAM policies to access ALB, DNS, ECR, ASG
eksctl create nodegroup --name=demo \
--managed \
--cluster=demo \
--tags "env=test,type=demo" \
--region=ap-south-1 \
--node-type=t2.micro \
--nodes=2 \
--nodes-min=2 \
--nodes-max=4 \
--node-volume-size=8 \
--ssh-access \
--ssh-public-key=ekstestpair \
--asg-access \
--external-dns-access \
--full-ecr-access \
--appmesh-access \
--appmesh-preview-access \
--alb-ingress-access
# Get NodeGroup
eksctl get nodegroup --cluster=demo
# Explore the cluster, check ASG, EKS Nodes Group, EC2, KeyPairs, IAM Policy
kubectl get nodes
kubectl get po -A
# Delete Node Group
eksctl delete nodegroup --cluster= --name=
eksctl delete nodegroup --cluster=demo --name=demo
```
## Demo App
```
# Create a Pod
kubectl run nginx --image=nginx --port=80
# Expose with LoadBalancer service
kubectl expose pod nginx --port=80 --type=LoadBalancer
# Delete the resources created
kubectl delete po/nginx svc/nginx
```
