Kubernetes：如何解决从k8s.gcr.io拉取镜像失败问题
简介新版本的Kubernetes在安装部署中，需要从k8s.grc.io仓库中拉取所需镜像文件，但由于国内网络防火墙问题导致无法正常拉取，本文将介绍如何绕过此问题，来完成业务的部署。
问题描述
使用Kubernetes V1.11.3版本部署集群业务，在进行kubeadm init时，需要从k8s.grc.io仓库拉取镜像：
You can also perform this action in beforehand using 'kubeadm config images pull'
Some fatal errors occurred:
: failed to pull image : exit status 1
: failed to pull image : exit status 1
: failed to pull image : exit status 1
: failed to pull image : exit status 1
: failed to pull image : exit status 1
: failed to pull image : exit status 1
: failed to pull image : exit status 1
If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`
解决方案
docker.io仓库对google的容器做了镜像，可以通过下列命令下拉取相关镜像：
docker pull mirrorgooglecontainers/kube-apiserver-amd64:v1.11.3
docker pull mirrorgooglecontainers/kube-controller-manager-amd64:v1.11.3
docker pull mirrorgooglecontainers/kube-scheduler-amd64:v1.11.3
docker pull mirrorgooglecontainers/kube-proxy-amd64:v1.11.3
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd-amd64:3.2.18
docker pull coredns/coredns:1.1.3
版本信息需要根据实际情况进行相应的修改。通过docker tag命令来修改镜像的标签：
docker tag docker.io/mirrorgooglecontainers/kube-proxy-amd64:v1.11.3 k8s.gcr.io/kube-proxy-amd64:v1.11.3
docker tag docker.io/mirrorgooglecontainers/kube-scheduler-amd64:v1.11.3 k8s.gcr.io/kube-scheduler-amd64:v1.11.3
docker tag docker.io/mirrorgooglecontainers/kube-apiserver-amd64:v1.11.3 k8s.gcr.io/kube-apiserver-amd64:v1.11.3
docker tag docker.io/mirrorgooglecontainers/kube-controller-manager-amd64:v1.11.3 k8s.gcr.io/kube-controller-manager-amd64:v1.11.3
docker tag docker.io/mirrorgooglecontainers/etcd-amd64:3.2.18 k8s.gcr.io/etcd-amd64:3.2.18
docker tag docker.io/mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag docker.io/coredns/coredns:1.1.3 k8s.gcr.io/coredns:1.1.3
使用docker rmi删除不用镜像，通过docker images命令显示，已经有我们需要的镜像文件，可以继续部署工作了：
# docker images

另外一种方法是通过国外的服务器下载镜像，然后保存镜像，具体操作见：https://bbs.cnblackhat.com/thread-2825-1-1.html
