12.3. 使用 systemd 运行 DHCP 插件

流程

1. 创建套接字单元文件：

   # cat /usr/lib/systemd/system/io.podman.dhcp.socket
   [Unit]
   Description=DHCP Client for CNI
   
   [Socket]
   ListenStream=%t/cni/dhcp.sock
   SocketMode=0600
   
   [Install]
   WantedBy=sockets.target

   Copy to Clipboard Toggle word wrap

2. 创建服务单元文件：

   # cat /usr/lib/systemd/system/io.podman.dhcp.service
   [Unit]
   Description=DHCP Client CNI Service
   Requires=io.podman.dhcp.socket
   After=io.podman.dhcp.socket
   
   [Service]
   Type=simple
   ExecStart=/usr/libexec/cni/dhcp daemon
   TimeoutStopSec=30
   KillMode=process
   
   
   [Install]
   WantedBy=multi-user.target
   Also=io.podman.dhcp.socket

   Copy to Clipboard Toggle word wrap

3. 立即启动该服务：

   # systemctl --now enable io.podman.dhcp.socket
