Puppet Class: named::caching

Defined in:
manifests/caching.pp

Summary

Configures a caching nameserver.

Overview

You will need to call named::caching::forwarders to make it useful.

There is also named::caching::root_hints which allows you to set the entire contents of the ‘named.ca’ hint file.

If you want something other than the defaults provided here, use the main named class.

Parameters:

  • chroot_path (Stdlib::Absolutepath) —

    The path to the chroot location.

    • Has no effect if SELinux is enforcing.

    • Defaults to ‘named::chroot_path` per module Hiera data.
