Windows安装Kubernetes

    环境依赖

    • 需要事先正确安装Docker Desktop
    • 笔记本最好不低于16G内存

    背景说明

    学习Kubernetes的第一步就需要搭建一个可用的Kubernetes环境，这里针对Windows的安装过程做简要记录

    解决方案

    事先安装Docker Desktop

    image.png

    日志目录

    安装过程中可能会出现错误需要我们及时查看日志来排查问题，日志目录:C:\ProgramData\DockerDesktop


    image.png

    版本确认

    首先确认当前需要安装的版本，从下图中可以看到需要安装的版本为v1.22.4


    image.png

    镜像配置

    确认镜像源配置为阿里云镜像加速


    image.png

    安装镜像

    由于国内的网络问题，直接启用Kubernetes会无法正常启动，如下图所示

    image.png
    此时在github开源库中提供了镜像的阿里云方案https://github.com/AliyunContainerService/k8s-for-docker-desktop
    image.png
    进行分支切换
    image.png
    找到对应需要安装的分支，并下载文件
    image.png
    文件下载后并解压
    image.png
    执行镜像下载命令
    image.png
    查看已有镜像
    image.png

    网络配置

    进入目录C:\Windows\System32\drivers\etc编辑文件hosts添加一行

    # Kubernetes
127.0.0.1 kubernetes.docker.internal
    image.png

    否则执行命令会出现如下错误

    PS D:\> kubectl.exe cluster-info
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
Unable to connect to the server: dial tcp: lookup kubernetes.docker.internal: no such host

    服务启用

    把勾勾上，等待一段时间，就会发现下发那个kubernetes的点变绿了，代表kubernetes启动成功


    image.png

    由于启动较慢，这里可以通过命令查看容器的启动状态


    image.png

    命令验证

    PS D:\> kubectl.exe  cluster-info
Kubernetes control plane is running at https://kubernetes.docker.internal:6443
CoreDNS is running at https://kubernetes.docker.internal:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

    此时即可以说明环境安装正常

    安装看板

    应用配置

    PS D:\k8s-for-docker-desktop-1.22.4> kubectl.exe apply -f  .\kubernetes-dashboard.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created

rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
deployment.apps/dashboard-metrics-scraper created

    安装进度

    PS D:\k8s-for-docker-desktop-1.22.4> kubectl get pod -n kubernetes-dashboard
