How to use

The most common use-case is to provide DHCP service to the host network of the machine running Docker. For that you need to create a configuration for the DHCP server, start the container with the --net host docker run option and specify the network interface you want to provide DHCP service on.

Create data folder.

Create data/dhcpd.conf with a subnet clause for the specified network interface. If you need assistance, you can run docker run -it --rm networkboot/dhcpd man dhcpd.conf for a description of the configuration file syntax. Run docker run -it --rm --init --net host -v "$(pwd)/data":/data networkboot/dhcpd net0. dhcpd will automatically start and display its logs on the console. You can press Ctrl-C to terminate the server.

..But, FIRST:

set the interfaces static address sudo ifconfig net0 172.17.1.1
then add a default route to your local machine sudo route add -net 172.17.1.0/32 gw 172.17.1.1 netmask 255.255.255.0 so that you can reach devices that have been assigned addresses from the dhcp server.

now you can run the dhcp server docker run -it --rm --init --net host -v "$(pwd)/data":/data networkboot/dhcpd net0
