Puppet Class: r_profile::linux::hostname

Defined in:
manifests/linux/hostname.pp

Overview

R_profile::Linux::Hostname

Set the hostname using systemd and optionally the system IP address. By default, set the hostname to match ‘certname` - the name of the signed certificate that puppet knows about. This is useful for cloud environments such as azure that assign dnsdomains based on regions that cannot be changed to a sensible default

Examples:

Set the hostname based on the puppet ‘certname`

include r_profile::linux::hostname

Parameters:

  • fqdn (String) (defaults to: hiera("r_profile::linux::hostname::fqdn", $trusted['certname'])) —

    The fully qualified hostname that this host should use for all names

  • ip (Optional[String]) (defaults to: hiera("r_profile::linux::hostname::ip", undef)) —

    The IP address of a corresponding entry to add to /etc/hosts if required
