KubernetesDocker Desktop

先决条件,你需要一个 Docker for Mac或者Docker for Windows的安装包,如果没有请下载下载 Docker CE最新版本,建议分配 4GB以上内存。

Docker for Mac ,Docker for Windows开启 Kubernetes

为 Docker daemon 配置 Docker Hub 的中国官方镜像加速 https://registry.docker-cn.com

由于Kubernetes大量的容器镜像在 gcr.io, 无法在国内保证稳定的访问。我们提供了一些工具脚本,帮助从阿里云镜像服务下载所需镜像

首先,

代码语言:javascript复制
git clone https://github.com/AliyunContainerService/k8s-for-docker-desktop
cd k8s-for-docker-desktop

预先从阿里云Docker镜像服务下载 Kubernetes 所需要的镜像, 可以通过修改 images.properties 文件加载你自己需要的镜像

代码语言:javascript复制
./load_images.sh

Windows打开Powershell执行

代码语言:javascript复制
.load_images.ps1

安装 kubectl

Mac下载kubectl二进制文件,下载最新版本

代码语言:javascript复制
curl -LO "https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl"

Windows

代码语言:javascript复制
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.19.0/bin/windows/amd64/kubectl.exe

赋予执行权限

代码语言:javascript复制
chmod  x ./kubectl

Mac 或linux 将其移动到bin目录下,Windows配置环境变量

代码语言:javascript复制
sudo mv ./kubectl /usr/local/bin/kubectl

开启Kubernetes

配置 Kubernetes

可选操作: 切换Kubernetes运行上下文至 docker-for-desktop

代码语言:javascript复制
kubectl config use-context docker-desktop

验证 Kubernetes 集群状态

代码语言:javascript复制
kubectl cluster-info
kubectl get nodes

部署 Kubernetes dashboard

代码语言:javascript复制
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.4/aio/deploy/recommended.yaml

代码语言:javascript复制
kubectl create -f kubernetes-dashboard.yaml

打开代理

代码语言:javascript复制
kubectl proxy

访问链接

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/.

提示输入tocken,创建Bearer Token

For Bash:

代码语言:javascript复制
kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk '{print $1}')

For Powershell:

代码语言:javascript复制
kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | sls admin-user | ForEach-Object { $_ -Split 's ' } | Select -First 1)

类似如下,拷贝token值粘贴即可访问:

代码语言:javascript复制
Name:         admin-user-token-v57nw
Namespace:    kubernetes-dashboard
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: admin-user
              kubernetes.io/service-account.uid: 0303243c-4040-4a58-8a47-849ee9ba79c1

Type:  kubernetes.io/service-account-token
