lighthouse.peer¶

class lighthouse.peer.Peer(name, ip, port=None)[source]¶

Bases: object

This class represents a host running a lighthouse reporter.

When a reporter script tells its discovery method that a node is up, it includes information about itself via this class so that writer scripts reading that information can coordinate their peers.

This is helpful for HAProxy as a way to generate “peers” config stanzas so instances of HAProxy in a given cluster can share stick-table data.

classmethod current()[source]¶

Helper method for getting the current peer of whichever host we’re running on.

serialize()[source]¶

Serializes the Peer data as a simple JSON map string.

classmethod deserialize(value)[source]¶

Generates a Peer instance via a JSON string of the sort generated by Peer.deserialize.

The name and ip keys are required to be present in the JSON map, if the port key is not present the default is used.
