```Dockerfile

#### Docker Cache { #docker-cache }

There's an important trick in this `Dockerfile`, we first copy the **file with the dependencies alone**, not the rest of the code. Let me tell you why is that.

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```

       c.NatsConn().Close()

      _ = c.Close()
     }))
     if stanConnection != nil {
      subscribe()
     }

    }
   }

  }()
 }))

 // Subscribe to subject
 subscribe()

                        } catch (final SmbException se) {
