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

簡介:
新版本的Kubernetes在安裝部署中，需要從k8s.grc.io倉庫中拉取所需鏡像文件，但由於國內網絡防火牆問題導致無法正常拉取，本文將介紹如何繞過此問題，來完成業務的部署。

問題描述:
使用Kubernetes V1.11.3版本部署集群業務，在進行kubeadm init時，需要從k8s.grc.io倉庫拉取鏡像：
 

[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=...`
 

解決方案: docker.io倉庫對google的容器做了鏡像，可以通過下列命令下拉取相關鏡像：

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
 

版本信息需要根據實際情況進行相應的修改。通過docker tag命令來修改鏡像的標簽：

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
