edgemesh 安装

实验环境

• VMware Workstation 16 Pro
• 3 台虚拟机
• CentOS-7-x86_64-Minimal-2009
• 4核8G，100G硬盘
• docker 20.10.2
• k8s v1.21.4
• kubeedge v1.12.1

安装说明

• 更新时间：2023.1.19

准备工作

清除所有节点的污点

kubectl taint nodes --all node-role.kubernetes.io/master-

给 k8s API 服务打标签

kubectl label services kubernetes service.edgemesh.kubeedge.io/service-proxy-name=""

设置边缘 Kube-API 端点
云节点

kubectl edit configmap cloudcore -n kubeedge

# 在 data.cloudcore.yaml 中修改 modules.dynamicController.enable 为 true
modules:
  ...
  dynamicController:
    enable: true

边缘节点

vim /etc/kubeedge/config/edgecore.yaml

modules:
  ...
  edged:
    ...
    tailoredKubeletConfig:
      ...
      clusterDNS:
      - 169.254.96.16
      clusterDomain: cluster.local
  ...
  metaManager:
    ...
    metaServer:
      enable: true

重启 cloudcore 和 edgecore

# 在云节点运行
kubectl delete po cloudcore-7879bd4b5b-5jgt6 -n kubeedge

# 在边缘节点运行
systemctl restart edgecore.service

测试

# 在边缘节点运行
curl 127.0.0.1:10550/api/v1/services

[root@edge2 ~]# curl 127.0.0.1:10550/api/v1/services

安装 edgemesh

下载 EdgeMesh

git clone https://github.com/kubeedge/edgemesh.git
cd edgemesh

安装 CRDs

kubectl apply -f build/crds/istio/

部署 edgemesh-agent
修改配置文件

vim ./build/agent/resources/04-configmap.yaml

# 设置中继节点
        relayNodes:
        - nodeName: cloud
          advertiseAddress:
          - 192.168.0.201

kubectl apply -f build/agent/resources/

检验部署结果

kubectl get all -n kubeedge -o wide
