An Ansible role to install/configure ISC-DHCP server(s)
- Configurable options
- Failover and load balancing ready
Define your DHCP Scopes
isc_dhcp_scopes:
- subnet: 192.168.250.0
default_lease_time: "{{ isc_dhcp_default_lease_time }}"
max_lease_time: "{{ isc_dhcp_max_lease_time }}"
netmask: 255.255.255.0
# Define scope specific options to configure
options:
- name: routers
value: 192.168.250.1
- name: subnet-mask
value: 255.255.255.0
- name: broadcast-address
value: 192.168.250.255
- name: domain-name-servers
value: "{{ isc_dhcp_name_servers|join (', ') }}"
range_start: 192.168.250.128
range_end: 192.168.250.224For failover define the following vars to fit your deployment...
isc_dhcp_failover_info:
# ansible_default_ipv4.address|ansible_enp0s8.ipv4.address
# Defines failover address for dhcp failover setup
failover_address: "{{ ansible_default_ipv4.address }}"
# Define Ansible inventory group that nodes belong to
failover_group: dhcp-nodes
# Define the node in which should be considered the primary
primary: "{{ groups['dhcp-nodes'][0] }}"
# Define the port to be used on primary node
primary_port: "519"
# Define the node in which should be considered the secondary
secondary: "{{ groups['dhcp-nodes'][1] }}"
# Define the port to be used on secondary node
secondary_port: "520"None
