实验环境
注：这里是arm版本，使用的M1安装的ubuntu虚拟机，其他版本需要找对应的版本
选择k3s版本并安装
使用版本号：v1.23.14+k3s1
# 因为使用1.25不支持helm chart
root@hao:~# helm install rancher rancher-latest/rancher \
> --namespace cattle-system \
> --set hostname=172.16.190.100.sslip.io \
> --set replicas=1 \
> --set bootstrapPassword=jshebuebyxg45h3
Error: INSTALLATION FAILED: chart requires kubeVersion: < 1.25.0-0 which is incompatible with Kubernetes v1.25.4+k3s1一行命令即可安装，等待大约一分钟左右

helm install rancher rancher-latest/rancher \
--namespace cattle-system \

NAME: rancher
LAST DEPLOYED: Sat Dec 3 09:12:02 2022
NAMESPACE: cattle-system
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Rancher Server has been installed.
NOTE: Rancher may take several minutes to fully initialize. Please standby while Certificates are being issued, Containers are started and the Ingress rule comes up.
Check out our docs at https://rancher.com/docs/
If you provided your own bootstrap password during installation, browse to https://172.16.190.100.sslip.io to get started.
If this is the first time you installed Rancher, get started by running this command and clicking the URL it generates:
```
echo https://172.16.190.100.sslip.io/dashboard/?setup=$(kubectl get secret --namespace cattle-system bootstrap-secret -o go-template='{{.data.bootstrapPassword|base64decode}}')
```
To get just the bootstrap password on its own, run:
```
kubectl get secret --namespace cattle-system bootstrap-secret -o go-template='{{.data.bootstrapPassword|base64decode}}{{ "\n" }}'
```
Happy Containering!root@hao:~# echo https://172.16.190.100.sslip.io/dashboard/?setup=$(kubectl get secret --namespace cattle-system bootstrap-secret -o go-template='{{.data.bootstrapPassword|base64decode}}')
https://172.16.190.100.sslip.io/dashboard/?setup=jshebuebyxg45h3
root@hao:~# kubectl get secret --namespace cattle-system bootstrap-secret -o go-template='{{.data.bootstrapPassword|base64decode}}{{ "\n" }}'
jshebuebyxg45h3最后一步，因为是在内网，需要添加hosts才能正常访问
cat /etc/hosts
172.16.190.100 172.16.190.100.sslip.io熟悉的界面出现了！ok大功告成！
