Environment Configuration Example (end to end)

[mic...@frobl.com]

I am really excited to learn vert.x, however, coming from a whole different world (Golang, NodeJS), I do not see *exactly how* to make vert.x read configuration from the environment.

http://vertx.io/blog/vert-x-application-configuration should provide an example that instead of reading from a configuration json file, it instead gets the variable from the environment. Our company never uses configuration files, and always configures from environment. 

I know that it *should* be obvious, and maybe it's the whiskey, maybe it's the lack of sleep, but I don't understand how to make the server listen on port 8082 reading from the environment's PORT value.

Thank you in advance!

  ConfigStoreOptions store = new ConfigStoreOptions();

  store.setType("env");

  ConfigRetrieverOptions options = new ConfigRetrieverOptions()

  .addStore(store);

  ConfigRetriever retriever = ConfigRetriever.create(vertx, options);

  

// There is no example code for what to *do* with retriever.

 

    vertx.createHttpServer()

        .requestHandler(router::accept)

        .listen(

               

                config().getInteger("PORT", 9999),

System.getEnv("PORT") ?

Hello,

There are several approaches.

1) The simplest being: System.getEnv(“PORT”) as Tim said.

2) If you need more complex scenario, where the configuration can comes from different locations and you need to handle “overrides” (for instance system properties overrides env variables), check http://vertx.io/docs/vertx-config/java/.
