Add support to registry in Netflix Eureka or Consul Service Discovery

[jsoladur]

If I want integrate in the Netflix microservices ecosystem, I need that I can config in the XML file the endpoint Eureka Service Registry or Consul Service Registry in order to registry this microservice, as if it were a real service

[Technolords]

Interesting idea and I see the benefit of this. Going to work on the Consul part first.

[Technolords]

Been playing and testing with it. Upon registration, I queried Consul for it's services:

{
    "mock-1": {
        "Kind": "",
        "ID": "mock-1",
        "Service": "mock-service",
        "Tags": [
            "mock"
        ],
        "Meta": {
            "GET": "/mock/get, /mock/*/get, /mock/1/get, /mock/*/get, /mock/1/get"
        },
        "Port": 9090,
        "Address": "192.168.10.23",
        "EnableTagOverride": false,
        "CreateIndex": 0,
        "ModifyIndex": 0,
        "ProxyDestination": "",
        "Connect": null
    }
}

... and the checks:

{
    "service:mock-1": {
        "Node": "97068118c16b",
        "CheckID": "service:mock-1",
        "Name": "Service 'mock-service' check",
        "Status": "passing",
        "Notes": "",
        "Output": "HTTP GET http://192.168.10.23:9090/mock/cmd?config=current: 200 OK Output: <SNIPPED/>",
        "ServiceID": "mock-1",
        "ServiceName": "mock-service",
        "ServiceTags": [
            "mock"
        ],
        "Definition": {},
        "CreateIndex": 0,
        "ModifyIndex": 0
    }
}

@josemariasoladuran is this something you wanted?

[jsoladur]

Yes, it's exatly that I wanted. Only one detail. Send Consul the URL of health check microservices mock, and implemented handleGet for URL /health. It's very important in order to Consul can check the live of the microservice mock. Thank you for your quickly support!

¿What happen with Eureka? It's a Netflix service registry and I think that it is the most used.

[jsoladur]

@Technolords is important that you can register the microservice mock in the more than one endpoint Consul or Eureka. Sometimes, the microservices ecosystems replicate service discovery

[Technolords]

Oke, I'll make this flexible so you can register with many service registries, so the mock becomes shared between clusters if needed to be.

Current configuration (prototype) looks like:

  <service-registration>
    <consul address="192.168.10.14" port="8500">
      <service address="192.168.10.10" port="9090" id="mock-1" name="mock-service" >
        <health-check enabled="true" interval="60s" deregister-after="90m"/>
      </service>
    </consul>
  </service-registration>

... so the extension will look like:

  <service-registration>
    <consul ... />
    <consul ... />
    <eureka ... />
    <eureka ... />
  </service-registration>

Btw, to answer your question regarding health checks. This is covered and working. An example of a failed health check looks like:
