Kubernete 本地开发/调试环境 minikube microk8s kubeadm拉取 k8s.gcr.io 问题

废话不说,linux下使用如下脚本,保证可以下载相关镜像

**脚本非原创,主要是作者原来的阿里云镜像库改为了微软Azure源  
,其原理是调用的是微软Azure的源去下载的相关docker镜像,然后通过tag改名为本地镜像.版本号根据具体按照情况,可以改变**

#!/bin/bash
    
    set -e
    
    # Check version in https://kubernetes.io/docs/reference/setup-tools/kubeadm/kubeadm-init/
    # Search "Running kubeadm without an internet connection"
    # For running kubeadm without an internet connection you have to pre-pull the required master images for the version of choice:
    KUBE_VERSION=v1.13.2
    KUBE_PAUSE_VERSION=3.1
    ETCD_VERSION=3.2.24
    DNS_VERSION=1.14.8
    CORE_DNS_VERSION=1.2.6
    
    GCR_URL=k8s.gcr.io
    ALIYUN_URL=gcr.azk8s.cn/google_containers
    
    images=(kube-proxy-amd64:${KUBE_VERSION}
    kube-proxy:${KUBE_VERSION}
    kube-scheduler-amd64:${KUBE_VERSION}
    kube-scheduler:${KUBE_VERSION}
    kube-controller-manager-amd64:${KUBE_VERSION}
    kube-controller-manager:${KUBE_VERSION}
    kube-apiserver-amd64:${KUBE_VERSION}
    kube-apiserver:${KUBE_VERSION}
    pause-amd64:${KUBE_PAUSE_VERSION}
    pause:${KUBE_PAUSE_VERSION}
    etcd-amd64:${ETCD_VERSION}
    etcd:${ETCD_VERSION}
    k8s-dns-sidecar-amd64:${DNS_VERSION}
    k8s-dns-kube-dns-amd64:${DNS_VERSION}
    coredns:${CORE_DNS_VERSION}
    k8s-dns-dnsmasq-nanny-amd64:${DNS_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
    docker images

执行完毕效果如图

**Dashboard [https://github.com/kubernetes/dashboard/releases][https_github.com_kubernetes_dashboard_releases] 目前暂时不支持1.13.x**

以下安装dashboard的yaml脚本只支持到1.12,镜像已经替换为阿里云,可以放心直接使用.使用命令kubectl apply -f x.yaml
