Open V*N docker搭建

使用 Docker 搭建 OpenVPN
要在 Docker 中搭建 OpenVPN，需要遵循以下步骤：

创建一个名为 docker-compose.yml 的文件，并使用以下内容：

cd /openvpn
1

vim docker-compose.yml

version: '3'
services:
  openvpn:
    cap_add:
      - NET_ADMIN
    image: kylemanna/openvpn
    container_name: openvpn
    ports:
      - "1194:1194/udp"
    volumes:
      - ./openvpn-data/conf:/etc/openvpn
    restart: always

配置iptables （vim /etc/sysconfig/iptables）

*nat

:INPUT ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:DOCKER - [0:0]

-A OUTPUT ! -d 127.0.0.0/8 -m addrtype --dst-type LOCAL -j DOCKER
-A DOCKER -i docker0 -j RETURN
COMMIT

启动iptables
systemctl restart iptables

运行以下命令以启动 OpenVPN：

chmod +x dokcer-compose.yml
mkdir openvpn-data
docker-compose up -d
运行以下命令以创建 OpenVPN 客户端配置文件：


$sudo  export CLIENTNAME=yyds
docker-compose run --rm openvpn ovpn_genconfig -u udp://VPN.SERVERNAME.COM
docker-compose run --rm openvpn ovpn_initpki
docker-compose run --rm openvpn easyrsa build-client-full CLIENTNAME nopass
docker-compose run --rm openvpn ovpn_getclient CLIENTNAME > CLIENTNAME.ovpn

将生成的 yyds.ovpn 文件下载到本地计算机，并将其导入到 OpenVPN 客户端中。
