aws eks 通过eksctl 创建nodegroup

参考官方文档：https://eksctl.io/usage/managing-nodegroups/

创建nodegroup命令

eksctl create nodegroup --cluster=<clusterName> [--name=<nodegroupName>]

例如

eksctl create nodegroup --cluster=faberbeta --name=high-memory-group

看样子这个方式不是很好，因为不能详细配置nodegroup服务器的配置

推荐使用--config-file指定配置文件来创建nodegroup

命令:

eksctl create nodegroup --config-file=high-memory-cluster.yaml

high-memory-cluster.yaml的配置文件

apiVersion: eksctl.io/v1alpha5
