1. K8S集群部署，可以参考如下博客

请安装k8s集群，centos安装k8s集群
请安装k8s集群，ubuntu安装k8s集群

2.安装kubEedge

2.1 编辑kube-proxy使用ipvs代理

kubectl edit configmaps kube-proxy -n kube-system #修改kube-proxy

#大约在40多行37     ipvs:38       excludeCIDRs: null39       minSyncPeriod: 0s40       scheduler: ""41       strictARP: true  #这里由原来的false修改为true42       syncPeriod: 0s43       tcpFinTimeout: 0s44       tcpTimeout: 0s45       udpTimeout: 0s46     kind: KubeProxyConfiguration47     metricsBindAddress: ""48     mode: "ipvs"  #这里原来是空的修改为ipvs49     nodePortAddresses: null50     oomScoreAdj: null51     portRange: ""52     showHiddenMetricsForVersion: ""53     winkernel:54       enableDSR: false55       forwardHealthCheckVip: false56       networkName: ""57       rootHnsEndpointName: ""58       sourceVip: ""

kubectl rollout restart daemonset kube-proxy -n kube-system
kubectl get pods -n kube-system

2.2 基础服务提供，负载均衡器metallb

#无网络情况下，先上传kubeedge.tar 和 metallb-native.yaml文件
docker load -i kubeedge.tar  #导入镜像#有网络可以直接拉去镜像
docker pull quay.io/metallb/controller:v0.13.5
docker pull quay.io/metallb/speaker:v0.13.5
wget https://raw.githubusercontent.com/metallb/metallb/v0.13.5/config/manifests/metallb-native.yaml

kubectl apply -f metallb-native.yaml
kubectl get pods -n metallb-system

[root@k8s-master01 ~]# kubectl get pods -n metallb-system

测试通过

kubectl delete -f nginx.yaml  #删除无用的pod和svc

3. 对于kubeEdge概述

KubeEdge由云和边缘组成。它建立在Kubernetes之上，为联网应用部署和云与边缘之间的元数据同步提供核心基础设施支持。所以如果我们想要设置KubeEdge，我们需要设置Kubernetes集群(可以使用现有的集群)，云端和边缘端在cloud side, 我们需要安装

Docker
Kubernetes cluster
cloudcore

在 edge side, 我们需要安装

Docker
MQTT （配置可以选用，不是一定需要）
edgecore

3.部署kubeedge cloudcore

3.1 获取keadm工具

#wget https://github.com/kubeedge/kubeedge/releases/download/v1.10.1/keadm-v1.10.1-linux-amd64.tar.gz
wget https://github.com/kubeedge/kubeedge/releases/download/v1.14.2/keadm-v1.14.2-linux-amd64.tar.gztar -zxvf keadm-v1.14.2-linux-amd64.tar.gz
cp keadm-v1.14.2-linux-amd64/keadm/keadm  /usr/local/bin/
keadm version

3.2 部署cloudcore

#在master上部署
#设置云端  使用keadm初始化，安装cloudcore
docker pull kubeedge/cloudcore:v1.14.2  
docker pull  kubeedge/iptables-manager:v1.14.2keadm init --advertise-address=192.168.110.100 --kubeedge-version=1.14.2   #这是master的ipkeadm init --advertise-address=192.168.186.200 --set iptablesManager.mode="external" --profile version=v1.14.2 #这里的IP是负载均衡器metallb分配的IP#以上参数分别为master节点地址和要安装的KubeEdge版本。#keadm reset  #安装错误可以重置
keadm gettoken  #获取token

[root@master ~]# keadm init --advertise-address=192.168.186.200 --set iptablesManager.mode="external" --profile version=v1.14.2  # 这里的IP是负载均衡器metallb分配的IP
Kubernetes version verification passed, KubeEdge installation will start...
