​KubeSphere离线无网络环境部署

KubeSphere离线无网络环境部署

KubeSphere 是 GitHub 上的一个开源项目，是成千上万名社区用户的聚集地。很多用户都在使用 KubeSphere 运行工作负载。对于在 Linux 上的安装，KubeSphere 既可以部署在云端，也可以部署在本地环境中，例如 AWS EC2、Azure VM 和裸机等。

KubeSphere 为用户提供轻量级安装程序 KubeKey（该程序支持安装 Kubernetes、KubeSphere 及相关插件），安装过程简单而友好。KubeKey 不仅能帮助用户在线创建集群，还能作为离线安装解决方案。

部署镜像仓库

# 导入镜像
root@cby:~/cby# docker load -i registry.tar

# 启动 Docker 仓库
root@cby:~# docker run -d   --restart=always   --name registry   -v "$(pwd)"/certs:/certs   -v /mnt/registry:/var/lib/registry   -e REGISTRY_HTTP_ADDR=0.0.0.0:443   -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt   -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key   -p 443:443   registry:2

#配置仓库

#在 /etc/hosts 中添加一个条目
root@cby:~# vim /etc/hosts
root@cby:~# cat /etc/hosts
3.7.191.234 dockerhub.kubekey.local

#配置免证书
root@cby:~# mkdir -p  /etc/docker/certs.d/dockerhub.kubekey.local
root@cby:~# cp certs/domain.crt  /etc/docker/certs.d/dockerhub.kubekey.local/ca.crt

#配置免验证
root@cby:~# cat /etc/docker/daemon.json
{
