## debops.dhcpd
[![Platforms](http://img.shields.io/badge/platforms-debian%20|%20ubuntu-lightgrey.svg)](#)
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:
---
# ---- Global ISC DHCP Server configuration ----
# Is this DHCP server authoritative?
dhcpd_authoritative: False
# List of network interfaces to listen on for DHCP requests
# If this list is empty, Ansible will try to guess correct interfaces
# automatically
dhcpd_interfaces: []
# Default domain to use
dhcpd_domain: '{{ ansible_domain }}'
# List of default DNS servers. By default, point users to the same host that
# serves them DHCP requests, on default interface. If this host is a router,
# you might need to set DNS server to internal interface IP address.
dhcpd_dns_servers: [ '{{ ansible_default_ipv4.address }}' ]
# Max lease time in hours (default lease time is calculated below)
dhcpd_lease_time: 24
# Default global options formatted as a text block
dhcpd_global_options: |
option domain-name "{{ ansible_domain }}";
option domain-name-servers {{ dhcpd_dns_servers | join(' ') }};
default-lease-time {{ (((dhcpd_lease_time / 2) + 6) * 60 * 60)|round|int }};
max-lease-time {{ (dhcpd_lease_time * 60 * 60)|round|int }};
log-facility local7;
# Custom options formatted as a text block
dhcpd_options: False
# ---- ISC DHCP Server configuration scopes ----
# These lists allow you to generate nested configuration scopes in
# dhcpd.conf. Most of the information about them can be found in dhcpd.conf(5)
# manual page. You can create nested configuration using Ansible variable
# expansion (examples below).
# List of general configuration parameters (work in any configuration scope):
# - comment: '' add a comment to a scope
# - options: | custom options for that scope defined as a text block
# - include: '' path to external file to include in this scope
# List of hosts (works in groups, subnets):
# - hosts: '' or [] list of hosts to configure in that scope; if this is
# a path to a file, dhcpd will include an external file
# in this scope
# List of parameters specific to dhcpd_classes:
# - class: '' class name
# - subclass: this is a hash with expression as key and additional
# options as value in a text block (see example below);
# each match expression must end with a colon to indicate
# hash key; optional
# List of parameters specific to dhcpd_groups:
# - subnets: [] list of subnet scopes to group together
# - groups: [] list of other group scopes to include. No recursion!
# List of parameters specific to dhcpd_shared_networks:
# - name: '' name of shared network
# - subnets: [] list of subnets in a shared network (do not use
# dhcpd_subnets here, because they will be duplicated
# and DHCP server will not start)
# List of parameters specific to dhcpd_subnets:
# - subnet: '' start of a subnet range (ie.: 192.168.1.0)
# - netmask: '' netmask for this subnet (ie.: 255.255.255.0)
# - routers: '' or [] address or list of addresses of gateway for that
# subnet (ie.: 192.168.1.1)
# List of parameters specific to dhcpd_hosts:
# - hostname: '' hostname, without domain part
# - address: '' IP address reserved for that host, optional
# - ethernet: '' Ethernet MAC address of this host, optional
# List of classes
dhcpd_classes: []
#- class 'example-class'
# subclass:
# 'match1':
# 'match2': |
# # match2 options in a text block;
#- class 'example-empty-class'
# List of groups
dhcpd_groups: []
#- comment: 'First group'
# hosts: '/etc/dhcp/dhcpd-group1-hosts.conf'
# groups: '{{ dhcpd_group_second }}'
# An example of group nesting
#dhcpd_group_second:
# - comment: 'Second group'
# hosts: '/etc/dhcp/dhcpd-group2-hosts.conf'
# List of shared networks
dhcpd_shared_networks: []
#- name: 'shared-net'
# comment: "Local shared network"
# subnets: '{{ dhcpd_subnets_local }}'
# options: |
# default-lease-time 600;
# max-lease-time 900;
# List of subnets not in a shared network
dhcpd_subnets:
- subnet: '{{ ansible_default_ipv4.network }}'
netmask: '{{ ansible_default_ipv4.netmask }}'
comment: 'Generated automatically by Ansible'
#- subnet: 'dead:be:ef::/64'
