Docker Desktop 启用 Kubernetes 失败后处理

一、环境

Windows 10 

C:\Users\zhuji>docker --version
Docker version 24.0.2, build cb74dfc

 

二、问题

 在setting -> Kubernetes 中，选中 Enable Kubernetes 后，长时间显示 Starting ...  ，在Images中显示几个自动下载的镜像后，显示 Start Kubernetes failed.

 

 

        查找资料发现，启用Kubernetes后，docker需要从国外源仓库下载一批镜像以便启用Kubernetes，这现国外的仓库访问速度较慢无法正常下载所需镜像，导致集群启用失败。根据这些资料所说，方法有二种，一种使用国内源，一种使用VPN。

 三、使用国内源

        在Setting -> Docker Engine   config中输入国内源地址

 "registry-mirrors": [
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://cr.console.aliyun.com/"
  ]

     然后无论重置Kubernetes ，重启Docker Desktop, 重启机器，均不能成功启动，Docker还会去国外源拉取镜像，此路不通。

四、外挂VPN

        启用VPN后，可以从国外源拉取到镜像文件，下载速度较慢，等一段时间后，可以看到docker 下载了10个镜像文件。

然后Kubernetes就启动成功了。

 

 

五、验证
