Unmaintained
Codacy is not using consul at the moment and for that reason we are not developing this library any more. Feel free to fork this and keep your own code.

An asynchronous Scala (http://scala-lang.org/) client for Consul (https://consul.io/)
on an sbt project add this line to your build.sbt:
libraryDependencies += "com.codacy" %% "scala-consul" % "1.1.0"
import Consul
import consul.Consul
instanciate a consul supplying an ip and a port indicating a working consul agent:
val myConsul = new consul.Consul(CONSUL_IP, CONSUL_PORT, Option(CONSUL_ACL_TOKEN))
import myConsul.v1._
now you can use the consul API as indicated in the official documentation (http://www.consul.io/docs/agent/http.html)
Example - add a tuple to the Key/Value store:
kv.put("myKey","myValue")
Example - query the registered nodes:
catalog.nodes().map{ case nodes =>
//do something with my nodes
}
Example - register a service with an http-check on the local node:
val myAddress = "127.0.0.1"
val myServicePort = 5000
val myServiceCheck = agent.service.httpCheck(s"http://localhost:$myServicePort/health","15s")
val myService = agent.service.LocalService(ServiceId("myServiceId"),ServiceType("myTypeOfService"),Set(ServiceTag("MyTag")),Some(myServicePort),Some(myServiceCheck),Some(Address(myAddress)))
agent.service.register(myService)
the check ID of the registered service-check is available via:
val myCheckId = myService.checkId
the other 2 types of checks are created with:
agent.service.ttlCheck
and
agent.service.scriptCheck
Error Handling:
All api methods return Futures that can fail. To parse Consul responses Play's Json library is used. In the unlikely case that the client cannot parse the response the Future will fail and you might want to access the JsError parsing resulted in. You can do so by recovering the Future:
import consul.v1.common.Types.ConsulResponseParseException
catalog.nodes().recover{
case ConsulResponseParseException(jsError) => //do something with the JsError
case NonFatal(otherException) => //something else
}
