Beacon to announce via Bonjour (zeroconf)
Broadcast values via zeroconf
If the announced values are static, it is advised to set run_once: True (do not poll) on the beacon configuration.
The following are required configuration settings:
servicetype - The service type to announce
port - The port of the service to announce
txt - The TXT record of the service being announced as a dict. Grains
can be used to define TXT values using one of following two formats:
grains.<grain_name>[i] where i is an integer representing the
index of the grain to use. If the grain is not a list, the index is
The following are optional configuration settings:
servicename - Set the name of the service. Will use the hostname from
host grain if this value is not set.
reset_on_change - If
True and there is a change in TXT records
detected, it will stop announcing the service and then restart announcing
the service. This interruption in service announcement may be desirable
if the client relies on changes in the browse records to update its cache
of TXT records. Defaults to
reset_wait - The number of seconds to wait after announcement stops
announcing and before it restarts announcing in the case where there is a
change in TXT records detected and
copy_grains - If
True, Salt will copy the grains passed into the
beacon when it backs them up to check for changes on the next iteration.
Normally, instead of copy, it would use straight value assignment. This
will allow detection of changes to grains where the grains are modified
in-place instead of completely replaced. In-place grains changes are not
currently done in the main Salt code but may be done due to a custom
plug-in. Defaults to
beacons: bonjour_announce: - run_once: True - servicetype: _demo._tcp - port: 1234 - txt: ProdName: grains.productname SerialNo: grains.serialnumber Comments: 'this is a test'
