使用KubeKey 离线环境部署 KubeSphere v3.0.0
作者：互联网
环境准备
以三台centos 7.7 64bit 为例：
| name | ip | role |
|---|---|---|
| node1 | 192.168.6.17 | etcd, master, worker |
| node2 | 192.168.6.18 | worker |
| node3 | 192.168.6.19 | worker |
确保机器已经安装所需依赖软件（sudo curl openssl ebtables socat ipset conntrack docker），离线环境下可使用私有源或者rpm包(centos类OS)或deb包(debian类OS)安装。
具体环境要求参见：https://github.com/kubesphere/kubekey/tree/release-1.0#requirements-and-recommendations
建议：可将安装了所有依赖软件的操作系统制作成系统镜像使用，避免每台机器都安装依赖软件，即可提升交付部署效率，又可避免依赖问题的发生。
如已有k8s集群，可将kubesphere相关镜像导入仓库之后使用ks-installer部署: https://github.com/kubesphere/ks-installer/tree/release-3.0
镜像仓库
可使用harbor或其他第三方镜像仓库。
如需快速部署自签名镜像仓库可参考：https://kubesphere.com.cn/forum/d/2240-docker-registry
安装包下载：
提示：由于包含所有组件镜像，该压缩包较大，如果网络不佳，可能会导致下载耗时较长。也可根据文档中的镜像列表将相关镜像导入私有镜像仓库中后使用kubekey自行安装。

curl -Ok https://kubesphere-installer.pek3b.qingstor.com/offline/v3.0.0/kubesphere-all-v3.0.0-offline-linux-amd64.tar.gz
安装步骤：
1. 创建集群配置文件
安装包解压后进入kubesphere-all-v3.0.0-offline-linux-amd64
./kk create config --with-kubesphere v3.0.0
修改生成的配置文件config-sample.yaml，也可使用-f参数自定义配置文件路径。kk详细用法可参考：https://github.com/kubesphere/kubekey
注意填写正确的私有仓库地址
privateRegistry（如已准备好私有仓库可设置为已有仓库地址，若计划使用kubekey创建私有仓库，则该参数设置为：dockerhub.kubekey.local）

2. 环境初始化 （可选）
若已安装相关依赖，并且已经准备好镜像仓库，可略过该步骤。 (为避免依赖问题的产生，建议提前安装相关依赖或使用已安装相关依赖的系统镜像执行安装)
注意：如需使用kk创建自签名镜像仓库，则会在当前机器启动docker registry服务，请确保当前机器存在
registry:2，如没有，可从kubesphere-images-v3.0.0/registry.tar中导入，导入命令：docker load < registry.tar
注意：由kk启动的镜像仓库端口为443，请确保所有机器均可访问当前机器443端口。镜像数据存储到本地/mnt/registry (建议单独挂盘)。
dependencies目录中仅提供了ubuntu16.04 (ubuntu-16.04-amd64-debs.tar.gz)、ubuntu18.04 (ubuntu-18.04-amd64-debs.tar.gz)以及centos7 (centos-7-amd64-rpms.tar.gz)的相关依赖包，其它操作系统可自行制作rpm或deb依赖包。打包规则为 r e l e a s e I D − {releaseID}- releaseID−{versionID}- o s A r c h − {osArch}- osArch−{debs or rpms}.tar.gz
# 执行如下命令会对配置文件中所有节点安装依赖：
./kk init os -f config-sample.yaml -s ./dependencies/
# 如需使用kk创建自签名镜像仓库，可执行如下命令：
./kk init os -f config-sample.yaml -s ./dependencies/ --add-images-repo
3. 导入镜像
进入kubesphere-all-v3.0.0-offline-linux-amd64/kubesphere-images-v3.0.0
使用push-images.sh将镜像导入之前准备的仓库中：
# 脚本后镜像仓库地址请填写真实仓库地址
./push-images.sh dockerhub.kubekey.local
如需自行到入镜像，可参考如下方法：
以kubesphere/kube-apiserver:v1.17.9为例docker tag kubesphere/kube-apiserver:v1.17.9 dockerhub.kubesphere.local/kubesphere/kube-apiserver:v1.17.9
注意: retag镜像时需要保留原始镜像的namespace
部署
以上准备工作完成且再次检查配置文件无误后，执行安装。
执行安装
./kk create cluster -f config-sample.yaml
