离线安装

下载文件

下载配置文件

wget https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/kubesphere-installer.yaml
wget https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/cluster-configuration.yaml

下载镜像脚本和列表文件

wget https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/offline-installation-tool.sh
wget https://github.com/kubesphere/ks-installer/releases/download/v3.4.1/images-list.txt
chmod +x offline-installation-tool.sh

下载卸载脚本

curl -L -o kubesphere-delete.sh https://raw.githubusercontent.com/kubesphere/ks-installer/release-3.4/scripts/kubesphere-delete.sh
chmod +x kubesphere-delete.sh

下载镜像包

如果docker.io仓库无法下载，可以参考官网提供的文档，在最下面有镜像清单，将其替换images-list.txt的内容。

./offline-installation-tool.sh -s -l images-list.txt -d ./kubesphere-images

推送镜像到仓库

将下载的镜像推送到镜像仓库中，可以参考安装registry或者harbor仓库

images_dir="./kubesphere-images" # 下载的镜像文件目录
images_list_file="./images-list.txt" # 镜像列表文件
registry_url="registry.lingo.local" # 镜像仓库地址，需要提前登录仓库
registry_namespace="kubesphereio" # 镜像仓库的命名空间
for file in $(ls ${images_dir})
do
	docker load -i ${images_dir}/${file}
done
for image in $(grep -E -v "^#|^$" ${images_list_file})
do
	image_local=$(echo ${image} | awk -F "/" '{print "'"${registry_url}/${registry_namespace}"'/"$NF}')
	docker tag ${image} ${image_local}
	docker push ${image_local}
done

修改配置文件

修改cluster-configuration.yaml

存储类安装参考openebs-hostpath

# vi +10 cluster-configuration.yaml
  persistence: # 存储类，为空则使用默认的
    storageClass: ""
  local_registry: "registry.lingo.local" # 镜像仓库地址
  namespace_override: "kubesphereio" # 镜像仓库的命名空间
  authentication:
    adminPassword: Admin@123 # KubeSphere的默认admin密码
    jwtSecret: ''
    oauthOptions:
      accessTokenMaxAge: 0h # 用户登录永不过期

修改kubesphere-installer.yaml

sed "s#kubesphere/ks-installer:v3.4.1#registry.lingo.local/kubesphereio/ks-installer:v3.4.1#" kubesphere-installer.yaml

安装KubeSphere

应用配置文件

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

查看安装日志

kubectl logs -n kubesphere-system -f deploy/ks-installer

卸载KubeSphere

先卸载可插拔组件，然后再卸载KubeSphere
