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 version3.2 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-address192.168.110.100 --kubeedge-version1.14.2 #这是master的ipkeadm init --advertise-address192.168.186.200 --set iptablesManager.modeexternal --profile versionv1.14.2 #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[rootmaster ~]# keadm init --advertise-address192.168.186.200 --set iptablesManager.modeexternal --profile versionv1.14.2 # 这里的IP是负载均衡器metallb分配的IP
Kubernetes version verification passed, KubeEdge installation will start...
