Kubernetes平台基本预装资源
kubernetes平台安装完成后需要安装基本资源， 本文适配 kubernetes-v1.21.1 版本
一、metrics-server
GitHub - kubernetes-sigs/metrics-server: Scalable and efficient source of container resource metrics for Kubernetes built-in autoscaling pipelines.

kubernetes官方使用nginx做的组件
自建集群使用裸金属安装方式
使用
- 给集群中需要暴露的nginx机器节点打上标签 node-role=ingress 如：
- kubectl label node k8s-master3 node-role=ingress kubectl label node k8s-node1 node-role=ingress kubectl label node k8s-node2 node-role=ingress kubectl label node k8s-node3 node-role=ingress
- 部署ingress的node节点会自动 开启 节点的 80和443 端口，保证这个机器端口不会被占用
- 默认ingress-nginx在每个节点没有CPU、MEMORY最大配额限制；可以按照公司架构需求修改resoources.limits相关字段
