ganeti-confd

ganeti-confd(8) 						   Version 2.5.2						   ganeti-confd(8)

Name
       ganeti-confd - Ganeti conf daemon

Synopsis
       ganeti-confd [-f] [-d]

DESCRIPTION

       ganeti-confd is a daemon used to answer queries related to the configuration of a Ganeti cluster.

       For testing purposes, you can give the -f option and the program won't detach from the running terminal.

       Debug-level message can be activated by giving the -d option.

   ROLE
       The  role of the conf daemon is to make sure we have a highly available and very fast way to query cluster configuration values.  This dae-
       mon is automatically active on all master candidates, and so has no single point of failure. It communicates via UDP so each query can eas-
       ily  be sent to multiple servers, and it answers queries from a cached copy of the config it keeps in memory, so no disk access is required
       to get an answer.

       The config is reloaded from disk automatically when it changes, with a rate limit of once per second.

       If the conf daemon is stopped on all nodes, its clients won't be able to get query answers.

   COMMUNICATION PROTOCOL
       The confd protocol is an HMAC authenticated json-encoded custom format, over UDP. A client library is provided to make  it  easy  to  write
       software  to  query  confd.  More information can be found in the Ganeti 2.1 design doc, and an example usage can be seen in the (external)
       NBMA daemon for Ganeti.
