Install and configure [ISC DHCP Server](https://www.isc.org/downloads/dhcp/).
|
|
|
|
### Installation
|
|
|
|
To install `debops.dhcpd` using Ansible Galaxy, run:
|
|
|
|
ansible-galaxy install debops.dhcpd
|
|
|
|
|
|
|
|
|
|
### Role variables
|
|
|

List of default variables available in the inventory:

|
|
# you might need to set DNS server to internal interface IP address.
|
|
dhcpd_dns_servers: [ '{{ ansible_default_ipv4.address }}' ]

|
# expansion (examples below).
