在CircleCI上设置虚拟专用网(L2TP)连接是一种在CI/CD环境中实现安全的远程访问的方法。L2TP(Layer 2 Tunneling Protocol)是一种用于建立虚拟专用网的协议,它通过在公共网络上创建加密的隧道来保护数据传输的安全性。
L2TP连接的设置步骤如下:
jobs:
setup-vpn:
docker:
- image: circleci/python:3.8
steps:
- run:
name: Install VPN client
command: |
sudo apt-get update
sudo apt-get install -y strongswan xl2tpd
- run:
name: Configure VPN connection
command: |
echo "conn my-vpn" | sudo tee /etc/ipsec.conf
echo " authby=secret" | sudo tee -a /etc/ipsec.conf
echo " auto=add" | sudo tee -a /etc/ipsec.conf
echo " keyingtries=3" | sudo tee -a /etc/ipsec.conf
echo " dpddelay=30" | sudo tee -a /etc/ipsec.conf
echo " dpdtimeout=120" | sudo tee -a /etc/ipsec.conf
echo " dpdaction=clear" | sudo tee -a /etc/ipsec.conf
echo " ike=aes256-sha1-modp1024!" | sudo tee -a /etc/ipsec.conf
echo " esp=aes256-sha1!" | sudo tee -a /etc/ipsec.conf
echo " type=transport" | sudo tee -a /etc/ipsec.conf
echo " left=%defaultroute" | sudo tee -a /etc/ipsec.conf
echo " leftprotoport=17/1701" | sudo tee -a /etc/ipsec.conf
echo " right=${VPN_SERVER_IP}" | sudo tee -a /etc/ipsec.conf
echo " rightprotoport=17/1701" | sudo tee -a /etc/ipsec.conf
echo " auto=start" | sudo tee -a /etc/ipsec.conf
echo "${VPN_SERVER_IP} %any: PSK \"shared-secret\"" | sudo tee /etc/ipsec.secrets

echo " refuse-pap" | sudo tee -a /etc/xl2tpd.conf
echo " refuse-chap" | sudo tee -a /etc/xl2tpd.conf
echo " refuse-mschap" | sudo tee -a /etc/xl2tpd.conf
echo " require-mppe-128" | sudo tee -a /etc/xl2tpd.conf
echo " name my-vpn" | sudo tee -a /etc/xl2tpd.conf
echo " pppoptfile /etc/ppp/options.l2tpd.client" | sudo tee -a /etc/xl2tpd.conf
echo "user" | sudo tee /etc/ppp/options.l2tpd.client
echo "password ${VPN_PASSWORD}" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "refuse-eap" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "refuse-pap" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "refuse-chap" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "refuse-mschap" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "require-mschap-v2" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "noccp" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "noauth" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "idle 1800" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "mtu 1410" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "mru 1410" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "defaultroute" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "replacedefaultroute" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "persist" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "noipdefault" | sudo tee -a /etc/ppp/options.l2tpd.client
echo "usepeerdns" | sudo tee -a /etc/ppp/options.l2tpd.client
- run:
name: Start VPN connection
command: |
sudo ipsec restart
sudo xl2tpd -D
- run:
name: Test VPN connection
command: |
ping -c 4 ${VPN_SERVER_IP}
以上配置将在CircleCI的构建过程中自动安装和配置L2TP客户端,并建立与L2TP服务器的连接。你可以根据需要自定义配置文件中的参数。
L2TP连接的优势是它提供了一种安全的远程访问方式,可以在CI/CD环境中方便地进行远程部署和测试。它适用于需要在CI/CD流程中进行远程访问的场景,例如远程部署到私有网络或虚拟机实例。
