mac- docker desktop 安装单体Kubernetes

1.安装mac-docker desktop  官网下载安装  https://www.docker.com/products/docker-desktop  

2.安装后查看版本

此文kubenetes版本为1.19.7  如果不是该版本需要自行修改配置

其他版本 可以参考 https://github.com/AliyunContainerService/k8s-for-docker-desktop 

3.如果想启动kubenetes 是很简单的 前提 可以科学上网 而且网速够快 设置里修改enable kubenetes  勾选打开 然后就是静静的等待  

4.如果想体验一把kubenetes 又不能科学上网 没有稳定的高网速 只能找国内的镜像 刚好国内有阿里云存在同步的镜像  我们可以直接使用 注意：没有下载镜像之前和没有第三部的条件 先不要开启kubenetes   开启了的话默认开始下载  会卡住 

5.首先下载好kubenetes 1.19.7 所需镜像  然后在开启

6.创建下载镜像文件 vim  load_images.sh 

#!/bin/bash
 
set -e
KUBE_VERSION=v1.19.7
KUBE_PAUSE_VERSION=3.2
ETCD_VERSION=3.4.13-0
COREDNS_VERSION=1.7.0
GCR_URL=k8s.gcr.io
ALIYUN_URL=registry.cn-hangzhou.aliyuncs.com/google_containers
 
# get images
images=(kube-proxy:${KUBE_VERSION}
    kube-scheduler:${KUBE_VERSION}
    kube-controller-manager:${KUBE_VERSION}
    kube-apiserver:${KUBE_VERSION}
    pause:${KUBE_PAUSE_VERSION}
    etcd:${ETCD_VERSION}
    coredns:${COREDNS_VERSION})
 
for imageName in ${images[@]} ; do
    docker pull $ALIYUN_URL/$imageName
    docker tag $ALIYUN_URL/$imageName $GCR_URL/$imageName
    docker rmi $ALIYUN_URL/$imageName
done
 
# show images
docker images

7.授予文件可执行权限 chmod +x ./load_images.sh

8.执行完成可看到镜像已经下载好 

 9.这时候 镜像准备就绪 可以打开 enable kubenetes  注意需要重启docker  如果没有看到kubenetes 为running

10.安装kubenetes 控制工具 kubectl

11.下载 kubernetes 1.19.7 下载地址：kubernetwindowses-client-darwin-amd64.tar.gz 

12. 解压  tar -zxvf kubernetwindowses-client-darwin-amd64.tar.gz

13. 移动文件到系统特定目录下 并且给本用户授权

chmod u+x && mv kubectl /usr/local/bin/kubectl

14. 查看kubectl version

15.查看一波node

kubectl -n kube-system get node 

16.查看pod

kubectl -n kube-system get pod

17.安装dashboard （可选）图形化界面方便查看 官网如 https://github.com/kubernetes/dashboard

18.下载dashboard 所需镜像 vim load_dashboard_images.sh

19. 

#!/bin/bash
set -e
KUBE_DASHBOARD_VERSION=v2.0.3
METRICS_SCRAPER=v1.0.4
KUBENETESUI_URL=kubernetesui
ALIYUN_KUBENETESUI_URL=registry.cn-hangzhou.aliyuncs.com/kubernetes_ns
 
# get images (ui)
imagesui=(dashboard:${KUBE_DASHBOARD_VERSION}
    metrics-scraper:${METRICS_SCRAPER})
 
for imageName in ${imagesui[@]} ; do
    docker pull $ALIYUN_KUBENETESUI_URL/$imageName
    docker tag $ALIYUN_KUBENETESUI_URL/$imageName $KUBENETESUI_URL/$imageName
    docker rmi $ALIYUN_KUBENETESUI_URL/$imageName
done
 
# show images
docker images

20.运行后可以看到 已经下载好的镜像

安装步骤如下 

Install

To deploy Dashboard, execute following command:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml

可能由于网络原因下载不到 recommended.yaml 现在提供一个该文件  直接复制到本地既可

Alternatively, you can install Dashboard using Helm as described at https://artifacthub.io/packages/helm/k8s-dashboard/kubernetes-dashboard.

Access

To access Dashboard from your local workstation you must create a secure channel to your Kubernetes cluster. Run the following command:

kubectl proxy

Now access Dashboard at:

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

 

安装成功后效果如下

使用token登录

通过以下脚本，配置访问控制台所需的令牌。

TOKEN=$(kubectl -n kube-system describe secret default| awk '$1=="token:"{print $2}')
kubectl config set-credentials docker-desktop --token="${TOKEN}"
echo $TOKEN

复制上述生成的令牌 选择token登录 粘贴到输入框 点击登录 既可登录成功

登录后界面如下
