KubeSphere安装

配置master节点

将​​kubeedge.enabled​​的​​false​​改为​​true​​

kubeedge: enabled: true # 将“false”更改为“true”。

kubeedge: cloudCore: cloudHub: advertiseAddress: - 172.16.0.22

查看安装过程

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f kubectl get node kubectl top node

配置边缘节点

边缘节点安装Docker-ce 19.03，​ ​镜像加速地址​​去自己的阿里云帐号申请

yum install docker-ce-19.03.15-3.el7 docker-ce-cli-19.03.15-3.el7 -y cat > /etc/docker/daemon.json <

配置 EdgeMesh

编辑 ​​/etc/nsswitch.conf​​

vi /etc/nsswitch.conf

修改hosts

hosts: dns files mdns4_minimal [NOTFOUND=return]

运行以下命令启用 IP 转发：

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf

检查验证

[root@edgenode-01 ~]# sysctl -p | grep ip_forward net.ipv4.ip_forward = 1

添加边缘节点

arch=$(uname -m); curl -LO && tar xvf keadm-v1.6.2-linux-$arch.tar.gz && chmod +x keadm && ./keadm join --kubeedge-version=1.6.2 --region=zh --cloudcore-ipport=192.168.0.10:10000 --quicport 10001 --certport 10002 --tunnelport 10004 --edgenode-name edgenode-vwuk --edgenode-ip 192.168.0.25 --token 805ca3c73ce17f447764d13c8bf95a73a683aa63674f760020e4da2c37a58667.eyJhbGciOinR5cCI6IkpXVCJ9.eyJleHAiOjE2MzAxMjI4NzR9.VVLBlOiSjjjLJjLSyz6dOcNl2A --with-edge-taint

如果使用的是云服务器搭建，那么添加防火墙和端口转发规则，需要将外网端口映射到相应的内网 IP 地址（主节点）和端口以及创建防火墙规则以允许流量进入这些端口（​​10000​​ 至 ​​10004​​）。添加完，直接将命令复制到边缘节点进行执行。

因为我用的是内网搭建，所以需要将命令里的端口都改为（​​30000​​ 至 ​​30004​​），改完后执行

arch=$(uname -m); curl -LO && tar xvf keadm-v1.6.2-linux-$arch.tar.gz && chmod +x keadm && ./keadm join --kubeedge-version=1.6.2 --region=zh --cloudcore-ipport=192.168.0.100:30000 --quicport 30001 --certport 30002 --tunnelport 30004 --edgenode-name edgenode-vwuk --edgenode-ip 192.168.0.25 --token 805ca3c73ce178bf960020e4da2c37a58667.eyJhbGciOiJIUzI1pXVCJ9.eyJleHAiOjE2MzAxMjI4NzR9.VVLBlOiSeVssi5gHmiHR6dOcNl2A --with-edge-taint

成功执行，显示如下

[Run as service] service file already exisits in /etc/kubeedge//edgecore.service, skip download kubeedge-v1.6.2-linux-amd64/ kubeedge-v1.6.2-linux-amd64/edge/ kubeedge-v1.6.2-linux-amd64/edge/edgecore kubeedge-v1.6.2-linux-amd64/cloud/ kubeedge-v1.6.2-linux-amd64/cloud/csidriver/ kubeedge-v1.6.2-linux-amd64/cloud/csidriver/csidriver kubeedge-v1.6.2-linux-amd64/cloud/admission/ kubeedge-v1.6.2-linux-amd64/cloud/admission/admission kubeedge-v1.6.2-linux-amd64/cloud/cloudcore/ kubeedge-v1.6.2-linux-amd64/cloud/cloudcore/cloudcore kubeedge-v1.6.2-linux-amd64/version KubeEdge edgecore is running, For logs visit: journalctl -u edgecore.service -b

此时，刷新边缘节点页面，会显示新添加的边缘节点，若没有出现，查看日志找错误信息

journalctl -u edgecore.service -f

移除边缘节点

边缘节点上执行

./keadm reset yum remove mosquitto rm -rf /var/lib/kubeedge /var/lib/edged /etc/kubeedge/ca /etc/kubeedge/certs

然后去master节点，移除边缘节点

kubectl delete node

在边缘节点运行pod

在master编写pod的yaml，因为边缘节点上有污点​​node-role.kubernetes.io/edge​​，所以需要设置pod的容忍度

apiVersion: v1 kind: Pod metadata: name: nginx-edge spec: containers: - name: nginx image: nginx ports: - containerPort: 80 hostPort: 80 tolerations: - key: "node-role.kubernetes.io/edge" operator: "Exists" effect: "NoSchedule"

部署

kubectl apply -y nginx-edge.yaml

可以看到，pod已经被调度到边缘节点edgenode-jkfy上

[root@k8s-master01 yaml]# kubectl get pod nginx-edge -o wide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES nginx-edge 1/1 Running 0 12m 172.17.0.2 edgenode-jkfy
