KubeSphere 官网地址：https://kubesphere.com.cn
离线装置 kubernetes 集群参考 sealyun 官网地址：https://www.sealyun.com

先装置好 kubernetes，离线装置 kubernetes 集群参考地址：https://www.sealyun.com
批改 Kubernetes 集群中所有节点中 docker 的 daemon.json 文件
```
vi /etc/docker/daemon.json
```
增加 Harbor 公有仓库地址
如果不配置后续在装置 KubeSphere 组件时候会发送 htts 申请，这里咱们是应用的 http，因为在内网离线环境中不须要应用 https
```
{
  "insecure-registries":
        ["192.168.28.150:8001"]
}
```

重启 docker 服务，让配置失效

systemctl daemon-reload
systemctl restart docker

登录 Harbor

docker login 192.168.28.150:8001 -u 用户名 -p 明码

1. 安装包
  在能够联网的机器上下载 NFS 安装包，当前在服务端和客户端装置应用。yum -y install nfs-utils --downloadonly --downloaddir /home/nfs
  下载好后打包上传到要装置的服务器中，执行上面命令开始装置
rpm -Uvh *.rpm --nodeps --force

2. 编辑配置文件
⚠️配置文件中的 * 是容许所有网段，依据本人理论状况写明网段
cat >/etc/exports <<EOF
/mnt/kubesphere *(insecure,rw,async,no_root_squash) 
EOF

3. 创立目录并批改权限
⚠️这里为了不便试验授予了挂载目录权限为 777，请依据理论状况批改目录权限和所有者
mkdir /mnt/kubesphere && chmod 777 /mnt/kubesphere

4. 启动服务
systemctl enable nfs-server rpcbind && systemctl start nfs-server rpcbind

在所有 node 节点中装置 NFS 客户端

rpm -Uvh *.rpm --nodeps --force

创立文件 vi storageclass.yaml 内容如下：

cat >storageclass.yaml <<EOF

利用 storageclass.yaml
```
kubectl apply -f storageclass.yaml
```

设置默认 strorageclass

kubectl patch storageclass nfs-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

验证

kubectl get pods

nfs-client-provisioner-7b9746695c-nrz4n   1/1     Running   0          2m38s

查看默认存储

kubectl get sc

当您在离线环境中装置 KubeSphere 时，须要当时筹备一个蕴含所有必须镜像的镜像包。

应用以下命令从可能拜访互联网的机器上下载镜像清单文件 images-list.txt：
```
curl -L -O https://github.com/kubesphere/ks-installer/releases/download/v3.1.0/images-list.txt
```

该文件依据不同的模块列出了 ##+modulename 下的镜像。您能够依照雷同的规定把本人的镜像增加到这个文件中。要查看残缺文件，请参见附录。

下载 offline-installation-tool.sh。

curl -L -O https://github.com/kubesphere/ks-installer/releases/download/v3.1.0/offline-installation-tool.sh

使 .sh 文件可执行。
```
chmod +x offline-installation-tool.sh
```

您能够执行命令 ./offline-installation-tool.sh -h 来查看如何应用脚本：

root@master:/home/ubuntu# ./offline-installation-tool.sh -h
Usage:
 
./offline-installation-tool.sh [-l IMAGES-LIST] [-d IMAGES-DIR] [-r PRIVATE-REGISTRY] [-v KUBERNETES-VERSION]
 
Description:
-b                     : save kubernetes' binaries.
-d IMAGES-DIR          : the dir of files (tar.gz) which generated by `docker save`. default: ./kubesphere-images
-l IMAGES-LIST         : text file with list of images.
-r PRIVATE-REGISTRY    : target private registry:port.
-s                     : save model will be applied. Pull the images in the IMAGES-LIST and save images as a tar.gz file.
-v KUBERNETES-VERSION  : download kubernetes' binaries. default: v1.17.9
-h                     : usage message

在 offline-installation-tool.sh 中拉取镜像。
```
./offline-installation-tool.sh -s -l images-list.txt -d ./kubesphere-images
```
推送镜像至公有仓库

将打包的镜像文件传输至您的本地机器，并运行以下命令把它推送至仓库。

./offline-installation-tool.sh -l images-list.txt -d ./kubesphere-images -r 192.168.28.150:8001/kubesphere-install

命令中的域名是 192.168.28.150:8001/kubesphere-install。请确保应用您本人仓库的地址。

与在现有 Kubernetes 集群上在线装置 KubeSphere 类似，您也须要当时下载 cluster-configuration.yaml 和 kubesphere-installer.yaml。

执行以下命令下载这两个文件，并将它们传输至您充当工作机的机器，用于装置。

curl -L -O https://github.com/kubesphere/ks-installer/releases/download/v3.1.0/cluster-configuration.yaml
curl -L -O https://github.com/kubesphere/ks-installer/releases/download/v3.1.0/kubesphere-installer.yaml

编辑 cluster-configuration.yaml 增加您的公有镜像仓库。例如，本教程中的仓库地址是 192.168.28.150:8001/kubesphere-install，将它用作 .spec.local_registry 的值，如下所示：

spec:
  persistence:
    storageClass: "" # 下面步骤曾经装置了 nfs 作为默认存储，这里就不须要指定了
  authentication:
    jwtSecret: ""
  local_registry: 192.168.28.150:8001/kubesphere-install # Add this line manually; make sure you use your own registry address.

您能够在该 YAML 文件中启用可插拔组件，体验 KubeSphere 的更多功能。无关详情，请参考启用可插拔组件。

编辑实现后保留 cluster-configuration.yaml。应用以下命令将 ks-installer 替换为您本人仓库的地址。

sed -i "s#^\s*image: kubesphere.*/ks-installer:.*#        image: 192.168.28.150:8001/kubesphere-install/kubesphere/ks-installer:v3.1.0#" kubesphere-installer.yaml

命令中的仓库地址是 192.168.28.150:8001/kubesphere-install。请确保应用您本人仓库的地址。

确定实现下面所有步骤后，您能够执行以下命令。

kubectl apply -f kubesphere-installer.yaml
kubectl apply -f cluster-configuration.yaml

查看装置日志：

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

验证装置
装置实现后，您会看到以下内容：
