@deffn {Scheme Variable} keepalived-service-type
This is the type for the @uref{https://www.keepalived.org/, Keepalived}
routing software, @command{keepalived}. Its value must be an
@code{keepalived-configuration} record as in this example for master
machine:
@lisp
(service keepalived-service-type
(keepalived-configuration
(config-file (local-file "keepalived-master.conf"))))
@end lisp
where @file{keepalived-master.conf}:
@example
vrrp_instance my-group @{
state MASTER
interface enp9s0
virtual_router_id 100
priority 100
unicast_peer @{ 10.0.0.2 @}
virtual_ipaddress @{
10.0.0.4/24
@}
@}
@end example
and for backup machine:
@lisp
(service keepalived-service-type
(keepalived-configuration
(config-file (local-file "keepalived-backup.conf"))))
@end lisp
where @file{keepalived-backup.conf}:
