# Como Fazer - Exemplos Práticos

Aqui você encontrará diferentes exemplos práticos ou tutoriais de "como fazer" para vários tópicos.

A maioria dessas ideias será mais ou menos **independente**, e na maioria dos casos você só precisará estudá-las se elas se aplicarem diretamente ao **seu projeto**.

Se algo parecer interessante e útil para o seu projeto, vá em frente e dê uma olhada. Caso contrário, você pode simplesmente ignorá-lo.

consequence, all volume mounts in containers are now `rslave` on Linux by default. To make this default work in all Linux environments the entire mount tree should be marked as shareable, e.g. via `mount --make-rshared /`. All Linux distributions that use systemd already have the root directory mounted as rshared and hence they need not do anything. In Linux environments without systemd we recommend running `mount --make-rshared /` during boot before docker is started, ([@jsafrane](https://github.com/jsafrane))...

OkCurl
======

_A curl for the next-generation web._

OkCurl is an OkHttp-backed curl clone which allows you to test OkHttp's HTTP engine (including
HTTP/2) against web servers.

To run locally, make sure you have GRAALVM_HOME set and run

```bash
