甲骨文云，搭建Docker专用机

第一步申请新实例

映像选 Canonical-Ubuntu
添加 SSH 密钥中为我生成密钥对保存私钥和公钥
添加 SSH 密钥中上载公共密钥文件 (.pub)，选择刚刚保存的公钥文件
安全列表清除全部规则

第二步 CF域名解析并配置iptables

域名解析，开启小云朵
ssh登录服务器
更改iptables

#!/bin/bash
/usr/sbin/iptables -P INPUT ACCEPT
/usr/sbin/iptables -P FORWARD ACCEPT
/usr/sbin/iptables -P OUTPUT ACCEPT
/usr/sbin/iptables -F
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 173.245.48.0/20 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 103.21.244.0/22 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 103.22.200.0/22 -j ACCEPT

/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 190.93.240.0/20 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 188.114.96.0/20 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 197.234.240.0/22 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 198.41.128.0/17 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 162.158.0.0/15 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 104.16.0.0/13 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 104.24.0.0/14 -j ACCEPT

sudo nano /etc/rc.local
sudo chmod +x /etc/rc.local
sudo systemctl enable rc-local
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service
重启服务器
sudo iptables -L 查看是否生效

#!/bin/sh -e 
## rc.local
#start script

#end script
echo "added sucessfully!" > /tmp/added_script.log 
exit 0

第三步安装docker

sudo apt update
sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce
sudo systemctl status docker
sudo curl -L "https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version

第四步安装 Nginx Proxy Manager

mkdir ngpm
cd ngpm
nano docker-compose.yml
sudo docker-compose up -d

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
