一键安装kubeedge测试环境

环境

  • 两台centos7虚拟机也
  • master需要免密码登录edge节点,如果拷贝秘钥,请先手动连一次接收指纹
  • 如果重新安装请参考下面的清理操作

安装

git clone  https://github.com/mengqiuyuwl/one-step-setup-kubeedge.git
MASTER_NODE=主节点的IP EDGE_NODE=边缘节点的IP bash install.sh

效果

master节点执行

查看节点,可以看到edgenode已经注册成功

kubectl get nodes
NAME         STATUS   ROLES    AGE   VERSION
10.10.8.44   Ready    master   28m   v1.16.3
edge-node    Ready    edge     28m   v1.15.3-kubeedge-v1.1.0-beta.0.205+19180d74ccb85c

查看应用我们可以看到服务已经运行在edge-node上面

kubectl get pods -o wide
NAME                                READY   STATUS    RESTARTS   AGE   IP           NODE        NOMINATED NODE   READINESS GATES
nginx-deployment-655748dfb6-zhl96   1/1     Running   0          27m   172.17.0.2   edge-node   <none>           <none>

清理

清理master node

如果需要清理请分别执行以下命令

pkill -9 cloudcore
rm -rf /usr/local/cloudcore
rm -rf /etc/kubeedge
kubeadm reset

清理edge node

pkill -9 edgecore
rm -rf /usr/local/edgecore
rm -rf /tmp/install-docker.sh
rm -rf /etc/kubeedge

污点耐受

安装后默认给edge节点添加了污点(taint),需要运行在edge上的服务需要通过pod亲和性选择到该节点上面,然后容忍(tolerations)edgenode的污点(taint)
