阿新 • • 發佈：2021-07-21
版本：v2.5
參考：https://docs.rancher.cn/docs/rancher2.5/quick-start-guide/_index
一、手動快速部署
執行以下命令：
docker run -d --privileged --restart=unless-stopped \
-p 80:80 -p 443:443 \
rancher/rancher:latest
結果： Rancher 已經安裝在了 Linux 主機上。
登入 Rancher 介面並配置初始設定：
https://<SERVER_IP>
二、部署工作負載
進入Rancher容器並執行一些操作：
