KubeEdge单机实验 2020-10-23 日常 暂无评论 5582 次阅读 # 单机实验 成功的例子：[Kubeedge安装,配置,HelloWorld](https://github.com/JingruiLea/blogs/blob/master/%E5%AE%89%E8%A3%85kubeedge.md) 在同一台WSL-Ubuntu子系统上，创建cloud、edge两个账户，来模拟云和边缘的服务器。 云和边缘将会使用同一个ip地址。 首先用`adduser`命令创建cloud和edge两个账户，账户密码设为1。 用原账户(pro)编译cloudcore，放到/home/cloud/；编译edgecore，放到/home/edge/。登录这三个账户，打开[KubeEdge文档](https://docs.kubeedge.io/en/latest/setup/local.html)，开始实验。 ## 一、部署云端 ### 1.生成配置文件 cloudcore自带新手配置文件，使用命令`cloudcore --minconfig > cloudcore.yaml`就能生成。生成的配置文件如下： ``` # With --minconfig , you can easily used this configurations as reference. # It's useful to users who are new to KubeEdge, and you can modify/create your own configs accordingly. # This configuration is suitable for beginners. apiVersion: cloudcore.config.kubeedge.io/v1alpha1 kind: CloudCore kubeAPIConfig: kubeConfig: /root/.kube/config master: "" leaderelection: LeaderElect: false LeaseDuration: 0s RenewDeadline: 0s ResourceLock: "" ResourceName: "" ResourceNamespace: "" RetryPeriod: 0s modules: cloudHub: advertiseAddress: - 172.17.101.196 https: address: 0.0.0.0 enable: true port: 10002 nodeLimit: 1000 tlsCAFile: /etc/kubeedge/ca/rootCA.crt tlsCAKeyFile: /etc/kubeedge/ca/rootCA.key tlsCertFile: /etc/kubeedge/certs/server.crt tlsPrivateKeyFile: /etc/kubeedge/certs/server.key unixsocket: address: unix:///var/lib/kubeedge/kubeedge.sock enable: true websocket: address: 0.0.0.0 enable: true port: 10000 ``` ### 2.运行cloudcore `cloudcore --config cloudcore.yaml` ``` cloud@LAPTOP-NI4DNH6I:~$ sudo ./cloudcore --config cloudcore.yaml F1023 10:39:22.813455 164 server.go:55] [ kubeconfig: Invalid value: "/root/.kube/config": kubeconfig not exist ] ``` 要给ubuntu系统（云服务器）也装一个k8s。Windows主系统装的k8s没用。 #### Ubuntu装k8s - 参考 - 1.[在 Ubuntu 上安装 K8S教程](https://www.cnblogs.com/whuanle/p/12260471.html) - 2.[Docker 镜像加速](https://www.runoob.com/docker/docker-mirror-acceleration.html) - 3.[Kubernetes在WSL部署的官方教程](https://kubernetes.io/blog/2020/05/21/wsl-docker-kubernetes-on-the-windows-desktop/) - 4.[kind文档](https://kind.sigs.k8s.io/docs/user/quick-start/) - 要点： - 参考1，中的镜像加速已经不能用了，配置镜像加速的部分要看参考2 - 要打开 Docker for Windows，不然用kind创建集群的第一步就出错 - 用`kubeadm init` 是运行不了的，会提示“没启动docker服务”和“不支持Swap"，让你用systemctl打开docker服务，并且禁用swap。由于WSL是以sysvinit启动的，不是systemd，所以用不了systemctl。用systemd代替sysvinit的方式行不通。正确的做法是按照参考3中的 [KinD: Kubernetes made easy in a container](https://kubernetes.io/blog/2020/05/21/wsl-docker-kubernetes-on-the-windows-desktop/#kind-kubernetes-made-easy-in-a-container) 写的，下载一个kind，覆盖掉从别处下载的kind。用`kind create cluster` 来代替`kubeadm init`来创建k8s集群和k8s控制面。 ``` cloud@LAPTOP-NI4DNH6I:~$ sudo kind create cluster --name wslkind Creating cluster "wslkind" ... ✓ Ensuring node image (kindest/node:v1.19.1) 🖼 ✓ Preparing nodes 📦 ✓ Writing configuration 📜 ✓ Starting control-plane 🕹️ ✓ Installing CNI 🔌 ✓ Installing StorageClass 💾 Set kubectl context to "kind-wslkind" You can now use your cluster with: kubectl cluster-info --context kind-wslkind Thanks for using kind! 😊 cloud@LAPTOP-NI4DNH6I:~$ kubectl version Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.3", GitCommit:"1e11e4a2108024935ecfcb2912226cedeafd99df", GitTreeState:"clean", BuildDate:"2020-10-14T12:50:19Z", GoVersion:"go1.15.2", Compiler:"gc", Platform:"linux/amd64"} The connection to the server localhost:8080 was refused - did you specify the right host or port? ``` 然后就发生了一件奇怪的事：cloud账户、root账户、edge账户都没发现k8s的服务端，只有pro账户发现了k8s的服务端 这是连不上的cloud： ``` cloud@LAPTOP-NI4DNH6I:~/.kube$ kubectl cluster-info To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

Unable to establish SSL connection. ``` 安装一个libssl-dev：`apt-get install libssl-dev` 关掉刚才的kind集群：`kind delete cluster --name wslkind` 重启Ubuntu子系统（在Windows里）：`wsl -t Ubuntu-20.04` 重新建一个kind集群：`kind create cluster'，没创建成功，提示： ``` root@LAPTOP-NI4DNH6I:/home/cloud# kind create cluster Creating cluster "kind" ... ✓ Ensuring node image (kindest/node:v1.19.1) 🖼 ✓ Preparing nodes 📦 ✓ Writing

refused - did you specify the right host or port? ``` 有可能是端口被占用了。把Docker for Windows 的k8s关掉，再试试： ``` root@LAPTOP-NI4DNH6I:/home/cloud# kind create cluster Creating cluster "kind" ... ✓ Ensuring node

use your cluster with: kubectl cluster-info --context kind-kind Not sure what to do next? 😅 Check out https://kind.sigs.k8s.io/docs/user/quick-start/ ``` 但还是连不上去： ``` root@LAPTOP-NI4DNH6I:/home/cloud#

GoVersion:"go1.13.15", Compiler:"gc", Platform:"linux/amd64"} Error from server (InternalError): an error on the server ("") has prevented the request from succeeding ``` 仔细看参考3，有一个[Docker Desktop: faster with WSL2](https://kubernetes.io/blog/2020/05/21/wsl-docker-kubernetes-on-the-windows-desktop/#docker-desktop-faster-with-wsl2)，意思是说不需要在Ubuntu子系统里安装Docker，只需要在Windows的Docker里打开一个开关，就能让Ubuntu子系统直接用Windows主系统里的Docker。 所以下一步是卸载Ubuntu子系统里的Docker。卸载过程完全参考[ubuntu 完全干净的卸载docker](https://www.cnblogs.com/shmily3929/p/12085163.html) 再`kind create cluster`创建集群的时候，卡在“Starting control-plane”这一步，这一步是调用kubeadm创建k8s的管理面，Ctrl+C退出，运行`kubeadm init`，发现除了原来的“docker服务未启用”、“不能用swap”以外，多了一个“端口被占用”错误。 在Windows主系统运行`netstat -aon|findstr "端口号"` 发现是com.docker.backend.exe在占用这个端口，而重启Docker也不能解除占用。于是重启电脑。 重启电脑以后，root用户进入Ubuntu子系统，先看一下`kubectl version`，不出意外，没有服务端。看一下 /root/.kube/config，因为KubeEdge的cloudcore用的将是/root/.kube里的config。结果是： ``` apiVersion: v1 clusters: ``` 看来是配置里真没有k8s服务端。用kind创建k8s集群：`kind create cluster --name balrog` ``` root@LAPTOP-NI4DNH6I:~/.kube# kind create cluster --name balrog Creating cluster "balrog" ... ✓ Ensuring node image (kindest/node:v1.19.1) 🖼 ✓ Preparing nodes 📦 ✓ Writing configuration 📜 ✓ Starting control-plane 🕹️ ✓ Installing CNI 🔌 ✓ Installing StorageClass 💾 Set kubectl context to "kind-balrog" You can now use your cluster with: kubectl cluster-info --context kind-balrog Have a nice day! 👋 ``` 创建成功了，再看一下 /root/.kube/config ： ``` apiVersion: v1 clusters: - cluster: certificate-authority-data: LS***Cg== server: https://127.0.0.1:45311 name: kind-balrog contexts: - context: cluster: kind-balrog user: kind-balrog name: kind-balrog current-context: kind-balrog kind: Config preferences: {} users: - name: kind-balrog user: client-certificate-data: LS***o= client-key-data: LS***o= ``` 配置文件里现在有k8s服务器了。最后再看一下这个k8s服务器有没有连上去：`kubectl version` ``` root@LAPTOP-NI4DNH6I:~/.kube# kubectl version Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.8", GitCommit:"9f2892aab98fe339f3bd70e3c470144299398ace", GitTreeState:"clean", BuildDate:"2020-08-13T16:12:48Z", GoVersion:"go1.13.15", Compiler:"gc", Platform:"linux/amd64"} Server Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.1", GitCommit:"206bcadf021e76c27513500ca24182692aabd17e", GitTreeState:"clean", BuildDate:"2020-09-14T07:30:52Z", GoVersion:"go1.15", Compiler:"gc", Platform:"linux/amd64"} ``` 连上去了。这个k8s服务器是运行在Windows的Docker里的，kubectl的配置文件是在Ubuntu的 /root/.kube/config 里的，Ubuntu装k8s就完成了。 ### #### 继续运行cloudcore 运行：`./cloudcore --config cloudcore.yaml` ``` E1023 17:01:15.074745 2759

kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/devices/devices_v1alpha2_device.yaml kubectl apply -f

https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/reliablesyncs/objectsync_v1alpha1.yaml ``` 再次运行：`./cloudcore --config cloudcore.yaml`，就不报错了。 ``` root@LAPTOP-NI4DNH6I:/home/cloud#

二、部署边缘 ### 1. 生成配置文件 `edgecore --minconfig > edgecore.yaml` ### 2. 运行edgecore 如果cloudcore和edgecore不在同一台主机，那就需要edge先连上cloud的k8s集群，获取token，放到edge的 ~/.kube/config里。 我这是运行在同一台主机里，不需要设置token，而是要运行一下这个命令：`export CHECK_EDGECORE_ENVIRONMENT="false"` 然后就能运行edgecore了：`edgecore --config edgecore.yaml` ``` I1023 17:28:55.647285 3193 log.go:181] INFO: Configuration files:

原来127.0.0.1:1883是mqtt服务端，我还没装mqtt，就先不管。配置文件里还出现了/etc/kubeedge/certs/server.crt，cat一下发现这个文件不存在，/etc/kubeedge 这个路径也不存在。 早先根据 [Kubeedge安装,配置,HelloWorld](https://github.com/JingruiLea/blogs/blob/master/%E5%AE%89%E8%A3%85kubeedge.md) 编译了keadm，是用来部署cloud和edge的。用这个来部署edge试试： ``` root@LAPTOP-NI4DNH6I:/home/edge# keadm join
