To set up a DHCP server within a Docker container for the fiber card network interface of the Docker host, you can follow these steps:

  1. Create a Docker network and specify the host network driver:
docker network create --driver=host mynetwork
  1. Create a Docker container for the DHCP server and map the network interface of the Docker host to the container:
docker run -d --net=mynetwork --name=mydhcpserver -v /var/run/docker.sock:/var/run/docker.sock rgielen/dhcpd
  1. Edit the configuration file for the DHCP server (/etc/dhcp/dhcpd.conf) to set the network parameters for the fiber card interface:
subnet 192.168.1.0 netmask 255.255.255.0 {
  range 192.168.1.100 192.168.1.200;
  option routers 192.168.1.1;
  option domain-name-servers 8.8.8.8, 8.8.4.4;
}
  1. Start the DHCP server container:
docker start mydhcpserver

Your DHCP server should now be running and providing IP addresses to devices connected to the network through the fiber card interface of the Docker host.
