Passing configuration to a verticle
Configuration in the form of Map can be passed to a verticle at deployment time:
val config = Json.obj(("name","tim"), ("directory","/blah"))
vertx.deployVerticle(ScalaVerticle.nameForVerticle[DemoVerticle].getName, DeploymentOptions().setConfig(config))
This configuration is then available via the Context
, The configuration is returned as a Map
object so you can retrieve data as follows:
println vertx.getOrCreateContext().config().getString("name")
Accessing environment variables in a Verticle
Environment variables and system properties are accessible using the Java API:
println System.getProperty("foo")
println System.getenv("HOME")
