AWS EKS 集群创建
创建方式
- AWS 管理控制台
- AWS 命令行工具
- eksctl 工具
- AWS 云开发工具包
一条命令启动eks集群
eksctl create cluster
- 自动生成集群名称
- 2x m5.large节点
- 自动选择AWS EKS AMI
- 默认 us-west-2 region
- 自动创建VPC
使用配置文件创建集群
创建cluster.yaml文件：
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
name: basic-cluster
region: ap-northeast-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/id_rsa.pub
指定文件创建
eksctl create cluster -f cluster.yaml
