How do I create a managed node group using Bottlerocket AMI in Amazon EKS?
I want to use eksctl to launch Bottlerocket Amazon Machine Image (Bottlerocket AMI) to create a managed node group in Amazon Elastic Kubernetes Service (Amazon EKS).
"I want to use eksctl to launch Bottlerocket Amazon Machine Image (Bottlerocket AMI) to create a managed node group in Amazon Elastic Kubernetes Service (Amazon EKS).ResolutionPrerequisite1.    Make sure that you have eksctl version 0.124.0 or later.2.    Run the following command to check your version:$ eksctl versionCreate a bottlerocket.yaml file1.    Open the terminal where you installed eksctl. Then, complete the following steps to create a new file.2.    Replace mybottlerocket-cluster with the name of your cluster. The name can contain only alphanumeric characters (case-sensitive) and hyphens. It must start with an alphabetic character and can't be longer than 100 characters.3.    Replace bottlerocket-nodegroup with a name for your node group. The name can contain only alphanumeric characters (case-sensitive) and hyphens. It must start with an alphabetic character and can't be longer than 100 characters.4.    Specify the instance type. For example, to deploy on an ARM instance, replace m5.xlarge with an ARM instance type.5.    Replace eks_bottlerocket with the name of an Amazon Elastic Compute Cloud (Amazon EC2) SSH key pair. After they're launched, use SSH to connect to the nodes.Note: If you don't have an Amazon EC2 SSH key pair, then create one in the AWS Management Console. For more information, see Amazon EC2 key pairs and Linux instances.6.    Replace all remaining values in the example with your own values. After you make the replacements, save the bottlerocket.yaml file.---apiVersion: eksctl.io/v1alpha5kind: ClusterConfig metadata:  name: mybottlerocket-cluster  region: us-west-2  version: '1.23' managedNodeGroups:  - name: bottlerocket-nodegroup    instanceType: m5.xlarge    minSize: 2    maxSize: 4    desiredCapacity: 3    amiFamily: Bottlerocket    labels: { role: br-worker }    tags:       nodegroup-type: Bottlerocket    ssh:      allow: true      publicKeyName: eks_bottlerocketNote: You can create Bottlerocket-managed node groups for all default instance types. These are static scaling (T series), general purpose (M series), compute-optimized (C series), memory-optimized (R series), and the Graviton2 ARM-based instance types. Bottlerocket AMI doesn't support accelerated computing instance types (P, G, Inf1).For more information on Bottlerocket AMI, see Amazon EKS optimized Bottlerocket AMIs.Create the node group and list its nodes in the EKS cluster1.    Run the following eksctl command to create a node group:$ eksctl create nodegroup -f bottlerocket.yaml[✔]  created 1 nodegroup(s) in cluster "mybottlerocket-cluster"2.    List the nodes in the EKS cluster along with your attributes:$ kubectl get nodes -o=custom-columns=NODE:.metadata.name,ARCH:.status.nodeInfo.architecture,OS-Image:.status.nodeInfo.osImage,OS:.status.nodeInfo.operatingSystemNODE                                          ARCH    OS-Image                                OSip-192-168-xx-xx.us-west-2.compute.internal   amd64   Bottlerocket OS 1.11.1 (aws-k8s-1.23)   linuxip-192-168-xx-xx.us-west-2.compute.internal   amd64   Bottlerocket OS 1.11.1 (aws-k8s-1.23)   linuxip-192-168-xx-xx.us-west-2.compute.internal   amd64   Bottlerocket OS 1.11.1 (aws-k8s-1.23)   linuxConnect to the Bottlerocket AMI nodes (optional)Connect to the new Bottlerocket nodes through an AWS Systems Manager (AWS SSM) session. The AWS SSM agent is running on the node because you already turned on AWS SSM permission for the node instance role. For more information on AWS SSM, see What is AWS Systems Manager?1.    Run the following command to find the instance IDs:$ kubectl get nodes -o=custom-columns=NODE:.metadata.name,ARCH:.status.nodeInfo.architecture,OS-Image:.status.nodeInfo.osImage,OS:.status.nodeInfo.operatingSystem,InstanceId:.spec.providerIDNODE                                           ARCH    OS-Image                                OS      InstanceIdip-192-168-xx-xx.us-west-2.compute.internal    amd64   Bottlerocket OS 1.11.1 (aws-k8s-1.23)   linux   aws:///us-west-2b/i-0cf32f13f60c2f501ip-192-168-xx-xx.us-west-2.compute.internal    amd64   Bottlerocket OS 1.11.1 (aws-k8s-1.23)   linux   aws:///us-west-2b/i-0f31328a5d21cb092ip-192-168-xx-xx.us-west-2.compute.internal    amd64   Bottlerocket OS 1.11.1 (aws-k8s-1.23)   linux   aws:///us-west-2b/i-08c218b729ecf9b5dStart an SSM sessionBy default, Bottlerocket has a control container that runs on a separate instance of containerd. This container runs the AWS SSM agent and lets you run commands or start interactive shell sessions on Bottlerocket nodes.1.    Choose one of the instances that you identified earlier and launch an SSM session. The following example shows an SSM session command for the i-0cf32f13f60c2f501 instance:$ aws ssm start-session --target i-0cf32f13f60c2f501 --region us-west-2Starting session with SessionId: EKS-Test-User-0077e4c89ad2bc888          Welcome to Bottlerocket's control container!Related informationLaunching self-managed Bottlerocket nodesWhat is Amazon EKS?Follow"
