【Rancher】单节点 Docker 快速部署

版本：v2.5

参考：https://docs.rancher.cn/docs/rancher2.5/quick-start-guide/_index

一、手动快速部署

执行以下命令：

docker run -d --privileged --restart=unless-stopped \
  -p 80:80 -p 443:443 \
  rancher/rancher:latest

结果： Rancher 已经安装在了 Linux 主机上。

登录 Rancher 界面并配置初始设置：

https://<SERVER_IP>

二、部署工作负载

参考：https://docs.rancher.cn/docs/rancher2.5/quick-start-guide/workload/quickstart-deploy-workload-nodeport/_index

进入Rancher容器并执行一些操作：

root@ubuntu20:~# docker exec -it goofy_banzai /bin/bash
root@9f3273caf126:/var/lib/rancher# apt-get update
root@9f3273caf126:/var/lib/rancher# apt-get install curl wget net-tools
root@9f3273caf126:/var/lib/rancher# netstat -tunlp
