K8S: mac osx 环境安装

一：MAC系统安装最新的Docker版本(18.6.0)，安装好之后启动Docker容器，切换到Kubernetes如图勾选

docker osx 控制面板

二：有个地方要注意的是添加国内注册地址(GreatWall大家懂得)

设置国内镜像地址

三：在启动Kubernetes之前需要手动下载Kubernetes启动需要的插件，VPN土豪可以忽略

1：选择一个文件夹新建images.properties文件，添加如下(替换镜像地址)

k8s.gcr.io/pause-amd64:3.1=registry.cn-hangzhou.aliyuncs.com/google_containers/pause-amd64:3.1 k8s.gcr.io/kube-controller-manager-amd64:v1.10.3=registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager-amd64:v1.10.3 k8s.gcr.io/kube-scheduler-amd64:v1.10.3=registry.cn-hangzhou.aliyuncs.com/google_containers/kube-scheduler-amd64:v1.10.3 k8s.gcr.io/kube-proxy-amd64:v1.10.3=registry.cn-hangzhou.aliyuncs.com/google_containers/kube-proxy-amd64:v1.10.3 k8s.gcr.io/kube-apiserver-amd64:v1.10.3=registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver-amd64:v1.10.3 k8s.gcr.io/etcd-amd64:3.1.12=registry.cn-hangzhou.aliyuncs.com/google_containers/etcd-amd64:3.1.12 k8s.gcr.io/k8s-dns-sidecar-amd64:1.14.8=registry.cn-hangzhou.aliyuncs.com/google_containers/k8s-dns-sidecar-amd64:1.14.8 k8s.gcr.io/k8s-dns-kube-dns-amd64:1.14.8=registry.cn-hangzhou.aliyuncs.com/google_containers/k8s-dns-kube-dns-amd64:1.14.8 k8s.gcr.io/k8s-dns-dnsmasq-nanny-amd64:1.14.8=registry.cn-hangzhou.aliyuncs.com/google_containers/k8s-dns-dnsmasq-nanny-amd64:1.14.8 k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.3=registry.cn-hangzhou.aliyuncs.com/google_containers/kubernetes-dashboard-amd64:v1.8.3

2：新建kubernetes.sh(名字可以自己定义)

#/bin/bash file="./images.properties" if [ -f "$file" ] then echo "$file found." while IFS='=' read -r key value do #echo "${key}=${value}" docker pull ${value} docker tag ${value} ${key} docker rmi ${value} done < "$file" else echo "$file not found." fi

3：切换到当前文件目录下执行脚本./kubernetes.sh，执行完成后查看镜像

配置图

4：我这里安装了portainer，docker图形化UI界面，浏览器输入http://localhost:9000；下载好镜像之后在Kubernetes页面点击Apply，等待Kubernetes启动

web图形界面

5：可以看到Kubernetes相关镜像已经启动

四：在docker环境下执行kubectl config use-context docker-for-desktop

执行页面

六：当前kubernetes.sh文件加下添加kubernetes-dashboard.yaml文件，定义UI界面内容

apiVersion: v1 kind: Secret metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard-certs namespace: kube-system type: Opaque --- # ------------------- Dashboard Service Account ------------------- # apiVersion: v1 kind: ServiceAccount metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard namespace: kube-system --- # ------------------- Dashboard Role & Role Binding ------------------- # kind: Role apiVersion: rbac.authorization.k8s.io/v1 metadata: name: kubernetes-dashboard-minimal namespace: kube-system rules: # Allow Dashboard to create 'kubernetes-dashboard-key-holder' secret. - apiGroups: [""] resources: ["secrets"] verbs: ["create"] # Allow Dashboard to create 'kubernetes-dashboard-settings' config map. - apiGroups: [""] resources: ["configmaps"] verbs: ["create"] # Allow Dashboard to get, update and delete Dashboard exclusive secrets. - apiGroups: [""] resources: ["secrets"] resourceNames: ["kubernetes-dashboard-key-holder", "kubernetes-dashboard-certs"] verbs: ["get", "update", "delete"] # Allow Dashboard to get and update 'kubernetes-dashboard-settings' config map. - apiGroups: [""] resources: ["configmaps"] resourceNames: ["kubernetes-dashboard-settings"] verbs: ["get", "update"] # Allow Dashboard to get metrics from heapster. - apiGroups: [""] resources: ["services"] resourceNames: ["heapster"] verbs: ["proxy"] - apiGroups: [""] resources: ["services/proxy"] resourceNames: ["heapster", "http:heapster:", "https:heapster:"] verbs: ["get"] --- apiVersion: rbac.authorization.k8s.io/v1 kind: RoleBinding metadata: name: kubernetes-dashboard-minimal namespace: kube-system roleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: kubernetes-dashboard-minimal subjects: - kind: ServiceAccount name: kubernetes-dashboard namespace: kube-system --- # ------------------- Dashboard Deployment ------------------- # kind: Deployment apiVersion: apps/v1beta2 metadata: labels: k8s-app: kubernetes-dashboard name: kubernetes-dashboard namespace: kube-system spec: replicas: 1 revisionHistoryLimit: 10 selector: matchLabels: k8s-app: kubernetes-dashboard template: metadata: labels: k8s-app: kubernetes-dashboard spec: containers: - name: kubernetes-dashboard image: k8s.gcr.io/kubernetes-dashboard-amd64:v1.8.3 ports: - containerPort: 8443 protocol: TCP args: - --auto-generate-certificates # Uncomment the following line to manually specify Kubernetes API server Host # If not specified, Dashboard will attempt to auto discover the API server and connect # to it.

执行

kubectl create -f kubernetes-dashboard.yaml

七：启动API Server

kubectl proxy Starting to serve on 127.0.0.1:8001

八：浏览器访问可以看到Kubernetes的Dashbord界面
