# 使用阿里云镜像源
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

# 创建本地仓库包
yum install --downloadonly --downloaddir=/root/k8sOfflineSetup/packages createrepo

# 安装实用工具
yum install --downloadonly --downloaddir=/root/k8sOfflineSetup/packages \
    yum-utils \
    nfs-utils \
    wget

# Docker依赖包
yum install --downloadonly --downloaddir=/root/k8sOfflineSetup/packages \
    device-mapper-persistent-data \
    lvm2

# 添加阿里云Docker源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# Docker安装包
yum install --downloadonly --downloaddir=/root/k8sOfflineSetup/packages \
    docker-ce-19.03.5 \

docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/etcd:3.4.3-0
docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.5

# 重新tag镜像
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-apiserver:v1.17.1 k8s.gcr.io/kube-apiserver:v1.17.1
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-controller-manager:v1.17.1 k8s.gcr.io/kube-controller-manager:v1.17.1

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/coredns:1.6.5 k8s.gcr.io/coredns:1.6.5

# 导出镜像为压缩包
docker save -o kube-apiserver-v1.17.1.tar k8s.gcr.io/kube-apiserver:v1.17.1
docker save -o kube-controller-manager-v1.17.1.tar k8s.gcr.io/kube-controller-manager:v1.17.1
