Gossip Registry

Gossip is a zero dependency registry which uses github.com/hashicorp/memberlist to broadcast registry information via the SWIM protocol.

Usage

Start with the registry flag or env var

MICRO_REGISTRY=gossip go run service.go

On startup you'll see something like

2018/12/06 18:17:48 Registry Listening on 192.168.1.65:56390

To join this gossip ring set the registry address using flag or env var

MICRO_REGISTRY_ADDRESS=192.168.1.65:56390
