# kubernetes与docker环境下命令整合【持续更新】 #

## 查看集群环境部署的服务 ##

kubectl  -s ip:port --namespace=kube-system cluster-info
    kubectl  -s ip:port cluster-info

## 主节点各类服务启停命令 ##

systemctl status docker
    systemctl status etcd
    systemctl status kubelet
    systemctl restart kubelet
    systemctl restart kube-proxy
    systemctl restart kube-apiserver
    systemctl restart kube-controller-manager
    systemctl restart kube-scheduler
    systemctl status kubelet kube-proxy kube-apiserver kube-controller-manager kube-scheduler #可同时多个服务一起查看

## 子节点各类服务启停命令 ##

systemctl restart kubelet
    systemctl restart kube-proxy
    systemctl status kubelet kube-proxy

## 查看最小节点Pod的应用情况 ##

kubectl  -s ip:port --namespace=kube-system get po
    kubectl  -s ip:port --namespace=kube-system get po -o wide #服务详情
    kubectl  -s ip:port --namespace=kube-system get po -o wide -w #动态监控服务运行

## 进入容器 ##

kubectl  -s ip:port --namespace=kube-system get po
    kubectl  -s ip:port --namespace=kube-system exec -ti 服务名 bash

## 查看Pod的yaml详细 ##

kubectl  -s ip:port --namespace=kube-system get po app-bdg5h -o yaml

## 查看Pod的label详细 ##

kubectl  -s ip:port --namespace=kube-system get node --show-labels

## 删除状态为Evicted 的Pod ##

kubectl  -s ip:port --namespace=kube-system get pods | grep Evicted | awk '{print $1}' | xargs kubectl  -s ip:port  --namespace=kube-system delete pod

## 复制文件到容器 ##

kubectl  -s ip:port --namespace=kube-system cp local_path 容器ID:容器目录

## 容器复制文件到系统 ##

kubectl  -s ip:port --namespace=kube-system cp 容器ID:容器目录 local_path
