Two 、 Imperative creation

2.1 establish Amazon EC2 Linux Managed node cluster

eksctl create cluster \
--name my-cluster \
--region us-west-2 \
--with-oidc \
--ssh-access \
--ssh-public-key <your-key> \
--managed

2.2 establish Fargate Linux node

eksctl create cluster \
--name my-cluster \
--region us-west-2 \
--fargate

2.3 See the resources

kubectl get nodes -o wide

2.4 Delete cluster

eksctl delete cluster --name my-cluster --region us-west-2

3、 ... and 、 The configuration file (yaml) establish

3.1 No choice VPC

nodeGroups Is an unmanaged node group ,managedNodeGroups by EKS Managed node group , Managed node groups can be displayed on the console .

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: basic-cluster
  region: eu-north-1

nodeGroups:
  - name: ng-1
    instanceType: m5.large
    desiredCapacity: 10
    volumeSize: 80
    ssh:
      allow: true # will use ~/.ssh/id_rsa.pub as the default ssh key
  - name: ng-2
    instanceType: m5.xlarge
    desiredCapacity: 2
    volumeSize: 100
    ssh:
      publicKeyPath: ~/.ssh/ec2_id_rsa.pub
managedNodeGroups:
  - name: ng-1-workers
    labels: {
     role: workers }
    instanceType: m5.xlarge
    desiredCapacity: 10
    volumeSize: 80
    privateNetworking: true
  - name: ng-2-builders
    labels: {
     role: builders }
    instanceType: m5.2xlarge
    desiredCapacity: 2
    volumeSize: 100
    privateNetworking: true

3.2 Select an existing VPC

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig

metadata:
  name: cluster-in-existing-vpc
  region: eu-north-1

vpc:
  subnets:
    private:
      eu-north-1a: {
     id: subnet-0ff156e0c4a6d300c }
      eu-north-1b: {
     id: subnet-0549cdab573695c03 }
      eu-north-1c: {
     id: subnet-0426fb4a607393184 }

nodeGroups:
  - name: ng-1-workers
    labels: {
     role: workers }
    instanceType: m5.xlarge
    desiredCapacity: 10
    privateNetworking: true
  - name: ng-2-builders
    labels: {
     role: builders }
    instanceType: m5.2xlarge
    desiredCapacity: 2
    privateNetworking: true
    iam:
      withAddonPolicies:
        imageBuilder: true

3.3 Run the create command

eksctl create cluster -f cluster.yaml

3.4 Delete cluster

eksctl delete cluster -f cluster.yaml
