With dhcp plugin the containers can get an IP allocated by a DHCP server already running on your network. This can be especially useful with plugin types such as macvlan. Because a DHCP lease must be periodically renewed for the duration of container lifetime, a separate daemon is required to be running. The same plugin binary can also be run in the daemon mode.
To use the dhcp IPAM plugin, first launch the dhcp daemon:
# Make sure the unix socket has been removed
$ rm -f /run/cni/dhcp.sock
$ ./dhcp daemon
If given -pidfile <path>
arguments after 'daemon', the dhcp plugin will write
its PID to the given file.
Alternatively, you can use systemd socket activation protocol. Be sure that the .socket file uses /run/cni/dhcp.sock as the socket path.
With the daemon running, containers using the dhcp plugin can be launched.
