dhcpd

Install and configure ISC DHCP Server.

Installation

This role requires at least Ansible v1.7.0. To install it, run:

ansible-galaxy install debops.dhcpd

Are you using this as a standalone role without DebOps?

You may need to include missing roles from the DebOps common playbook into your playbook.

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)

#                           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
