bixby-sd

This suite of components provides service discovery functionality to applications using Bixby.js. Service discovery is the cornerstone of an effective microservices architecture. Each service advertises its capabilities, allowing other services to utilize that functionality when needed.

Install

$ npm install bixby-sd

Usage

To utilize service discovery components, register them with the IoC container. The standard namespace for these components is sd.

IoC.use('sd', require('bixby-sd'));

Components

• Registry

Registry

exports['@require'] = [ 'sd/registry' ];

The registry component provides a service registry where a service can announce its capabilities as well as resolve other services. The interface supported by this component is defined by Registry.

Support for service registries is pluggable, allowing engineering teams to choose the registry that best meets their requirements. The type of registry to use is determined via configuration settings.

ZooKeeper

Apache ZooKeeper can be used as a service registry by specifying a zk:// URL in the [sd] section. The Registry instance is constructed from the sd-zookeeper module.

[sd]
url = "zk://127.0.0.1:2181"

etcd

etcd can be used as a service registry by specifying an etcd:// URL in the [sd] section. The Registry instance is constructed from the sd-etcd module.

[sd]
url = "etcd://127.0.0.1:4001"

When using etcd, the following settings are also supported:

• {integer} [ttl] - TTL of any announced services, auto updated by heartbeats
