Execute this example python program to watch for RabbitMQ events on the console.

```py
python rabbit.py
```

Open another terminal and upload a JPEG image into `images` bucket.

 * <p>As an example, imagine that we have a list of tasks to execute, but we don't want to submit
 * more than 2 per second:
 *
 * <pre>{@code
 * final RateLimiter rateLimiter = RateLimiter.create(2.0); // rate is "2 permits per second"
 * void submitTasks(List<Runnable> tasks, Executor executor) {
 *   for (Runnable task : tasks) {
 *     rateLimiter.acquire(); // may wait
 *     executor.execute(task);
 *   }
 * }
 * }</pre>

You can then replace the existing file with this new downloaded version. 
### Java Toolchain

The Gradle build uses [Java Toolchain](https://docs.gradle.org/current/userguide/toolchains.html) support to compile and execute tests across multiple versions of Java.

Available JDKs on your machine are automatically detected and wired for the various compile and test tasks.

A "**callable**" in Python is anything that Python can "call" like a function.

So, if you have an object `something` (that might _not_ be a function) and you can "call" it (execute it) like:

```Python
something()
```

or

```Python
something(some_argument, some_keyword_argument="foo")
```

then it is a "callable".

Note o `.` no final, é equivalente a `./`, ele diz ao Docker o diretório a ser usado para construir a imagem do contêiner.

Nesse caso, é o mesmo diretório atual (`.`).

### Inicie o contêiner Docker

* Execute um contêiner baseado na sua imagem:

<div class="termy">

```console
$ docker run -d --name mycontêiner -p 80:80 myimage
```

</div>
