kubeadm init [ERROR ImagePull]: failed to pull image [k8s.gcr.io/kube-apiserver-amd64:v1.11.3]: exit status 1

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：
 

[preflight/images] You can also perform this action in beforehand using 'kubeadm config images pull'
[preflight] Some fatal errors occurred:
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/kube-apiserver-amd64:v1.11.3]: exit status 1
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/kube-controller-manager-amd64:v1.11.3]: exit status 1
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/kube-scheduler-amd64:v1.11.3]: exit status 1
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/kube-proxy-amd64:v1.11.3]: exit status 1
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/pause:3.1]: exit status 1
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/etcd-amd64:3.2.18]: exit status 1
    [ERROR ImagePull]: failed to pull image [k8s.gcr.io/coredns:1.1.3]: exit status 1
[preflight] 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
