discovery-hostname-selector

A map of ssh public keys to install for the root user

This param sets the Discovery BootEnv (typically used to discover and create new machine objects when a Machine is Unknown to DRP) mechanism for assigning a machine hostname.

The configurable values are:

  • reverse-dns (the default): Attempt a Reverse IP lookup of the Machines assigned IP address, and use that
  • d-mac use the MAC address in the form d00-00-00-12-34-56
  • external-template: allow operator to provide custom template to assign hostname
  • random: Generates an 8 character random string for the hostname

In all cases, if the selected mechanism fails, then the fall-through default behavior of using the dMAC process (eg. d00-00-00-12-34-56) will be used. This allows Discovery to complete successfully.

For the external-template method, please review the Documentation of the discovery-hostname-template Param on how to correctly use it. You MUST specify an external template on the system to use this value, otherwise, the dMAC assignment for hostname and Machine object Name will be used.

Note

If a hostname is specified in the DHCP lease mechanism, this will be honored and take precedence over any settings used by this Param.

Note

This param will generally have to be applied at the Global profile level, as the Discovery BootEnv is used to create new machine objects for Unknown Machines.
