Petals Registry Overlay

The Registry Overlay has a member configuration containing an host to contact it, but it is only present to be communicated to other overlay nodes (this is how hazelcast work).

If we want to restrict to which interface a Registry Overlay should listen (as an hazelcast member thus), we should use the Interfaces option of the NetworkConfig.

Currently it is not possible to configure it, we should add the following configuration in member.properties to specify the address to listen to:

• petals.registry.overlay.member.listening.interface

The format is either:

• an accepted value by hazelcast (see http://docs.hazelcast.org/docs/3.5/manual/html/networkconfiguration.html#interfaces).
• 0.0.0.0 (it will disable the use a of a specific interface and bind to 0.0.0.0 aka all interfaces)
• an hostname that resolves to a local ip (if it does not, starting the registry will fail)

It will default to the host of the current member as declared in the cluster!
