Description

This module installs and configures ucarp on CentOS 7.

It allows you set up multiple virtual ip addresses with automatic failover by using ucarp.

Setup

puppet module install yoshz-ucarp

Usage

Add the module to node configuration:

node /host*/ {
  class { '::ucarp':
    bind_interface => 'ens160',
    password       => 'ProtectedPassword',
  }
  ucarp::host { '001':
    bind_interface  => 'ens160',
    vip_address     => '192.168.0.101',
    source_address  => '192.168.0.1',
    master_hostname => 'host001',
  }
  ucarp::host { '002':
    bind_interface  => 'ens160',
    vip_address     => '192.168.0.102',
    source_address  => '192.168.0.2',
    master_hostname => 'host002',
  }
}

Or add the following hiera configuration to your host group

ucarp::bind_interface: "ens160"
ucarp::password: ProtectedPassword
ucarp::hosts:
  '001':
    vip_address: 192.168.0.101
    master_hostname: host001
  '002':

    master_hostname: host002
  '003':
    vip_address: 192.168.0.103
