构建、拉取镜像和打gcr.io标签
拉取新构建的镜像
docker pull registry.cn-shenzhen.aliyuncs.com/cookcodeblog/kube-apiserver-amd64:v1.10.3
打上gcr.io同名标签
docker tag registry.cn-shenzhen.aliyuncs.com/cookcodeblog/kube-apiserver-amd64:v1.10.3 k8s.gcr.io/kube-apiserver-amd64:v1.10.3
删除新构建的镜像,只保留gcr.io镜像
docker rmi registry.cn-shenzhen.aliyuncs.com/cookcodeblog/kube-apiserver-amd64:v1.10.3
一个拉取kubeadm镜像的脚本
https://github.com/cookcodeblog/k8s-deploy/blob/master/kubeadm/04_pull_kubernetes_images_from_aliyun.sh
!/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=v1.10.3
KUBE_PAUSE_VERSION=3.1
ETCD_VERSION=3.1.12
DNS_VERSION=1.14.8
GCR_URL=k8s.gcr.io
ALIYUN_URL=registry.cn-shenzhen.aliyuncs.com/cookcodeblog
images=(kube-proxy-amd64:${KUBE_VERSION}
kube-scheduler-amd64:${KUBE_VERSION}
kube-controller-manager-amd64:${KUBE_VERSION}
kube-apiserver-amd64:${KUBE_VERSION}
pause-amd64:${KUBE_PAUSE_VERSION}
etcd-amd64:${ETCD_VERSION}
k8s-dns-sidecar-amd64:${DNS_VERSION}
k8s-dns-kube-dns-amd64:${DNS_VERSION}
k8s-dns-dnsmasq-nanny-amd64:${DNS_VERSION})
for imageName in ${images[@]} ; do
docker pull imageName
docker tag imageName imageName
docker rmi imageName
done
docker images
查看gcr.io官方镜像
https://console.cloud.google.com/gcr/images/google-containers/GLOBAL
然后再选择正确的镜像。
通常,gcr.io官方镜像的命名规则为:
gcr.io/google_containers/IMAGE_NAME:IMAGE_TAG
比如:
gcr.io/google_containers/kube-apiserver-amd64:v1.10.3
