kubegems 需要持久化一些重要数据，需要集群有可用的 CSI 插件
如果没有 CSI 插件，可以安装 local-path-provisioner
安装 local-path-provisioner
[root@k8s-master01 ~]# kubectl create namespace local-path-storage
namespace/local-path-storage created
[root@k8s-master01 ~]# kubectl apply -f addon-local-path-provisioner.yaml
plugin.plugins.kubegems.io/local-path-provisioner created
部署 kubegems 核心组件
[root@k8s-master01 ~]# kubectl create namespace kubegems
namespace/kubegems created
[root@k8s-master01 ~]# cat kubegems-mirror.yaml | grep local-path
storageClass: local-path # change me to use a production storage class # 改为您使用的 storageClass
[root@k8s-master01 ~]# cat kubegems-mirror.yaml | grep latest
kubegemsVersion: latest # change to specify kubegems version 改为上面查看的最新稳定版本或其他版本
修改后
kubegemsVersion: v1.21.6
[root@k8s-master01 ~]# mv kubegems-mirror.yaml kubegems.yaml
[root@k8s-master01 ~]# kubectl apply -f kubegems.yaml
plugin.plugins.kubegems.io/kubegems created
kubegems CR 下发后，大约需要 5 分钟才会一切正常，这取决于您的具体配置。
[root@k8s-master01 ~]# kubectl -n kubegems get pod

[root@k8s-master01 ~]# kubectl -n kubegems edit plugins.plugins.kubegems.io kubegems
plugin.plugins.kubegems.io/kubegems edited
或
[root@k8s-master01 ~]# kubectl edit svc -n kubegems kubegems-dashboard
访问kubegems
user: admin

添加集群
文件内容填
[root@k8s-master01 ~]# cat .kube/config
也可能为/etc/kubernetes/admin.conf或/etc/kubernetes/admin.yaml
Rancher
选择要安装的版本，这里选择稳定版 Stable
- 试用版 Latest
- 稳定版 Stable
- 测试版 Alpha
安装Helm
由于安装需要用helm包管理工具，已安装的可以忽略
[Helm GitHub](https://github.com/helm/helm/releases)
[root@k8s-master01 ~]# tar xf helm-v3.9.3-linux-amd64.tar.gz
[root@k8s-master01 ~]# cd linux-amd64/
[root@k8s-master01 linux-amd64]# mv helm /usr/local/bin/
[root@k8s-master01 linux-amd64]# helm version
version.BuildInfo{Version:"v3.9.3", GitCommit:"414ff28d4029ae8c8b05d62aa06c7fe3dee2bc58", GitTreeState:"clean", GoVersion:"go1.17.13"}
安装Rancher
[root@k8s-master01 ~]# helm repo add rancher-stable https://releases.rancher.com/server-charts/stable

Waiting for deployment "rancher" rollout to finish: 1 of 3 updated replicas are available...
deployment "rancher" successfully rolled out
检查Rancher是否运行成功
[root@k8s-master01 ~]# kubectl -n cattle-system rollout status deploy/rancher
deployment "rancher" successfully rolled out
[root@k8s-master01 ~]# kubectl -n cattle-system get deploy rancher

修改ClusterIP为NodePort，通过浏览器进行访问
[root@k8s-master01 ~]# kubectl get svc -n cattle-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
rancher ClusterIP 10.96.192.102 <none> 80/TCP,443/TCP 5m57s
