## Construindo uma Imagem Docker para FastAPI

Okay, vamos construir algo agora! 🚀

Eu vou mostrar como construir uma **imagem Docker** para FastAPI **do zero**, baseado na **imagem oficial do Python**.

Isso é o que você quer fazer na **maioria dos casos**, por exemplo:

* Usando **Kubernetes** ou ferramentas similares
* Quando rodando em uma **Raspberry Pi**

                fail("EOF while reading");
            }
            pos += r;
        }

        for ( int i = 0; i < offBuf.length; i++ ) {
            if ( offBuf[ i ] != 0 ) {
                fail("Not zero @ " + i);
            }
        }
    }


    /**
     * @param bufSize
     * @param length
     * @param is
     * @throws IOException
     */

		GetTrustedCa().
		GetInlineBytes()

	// seems as though the most straightforward way to tell whether this is a root ca or not
	// is to check whether the inline bytes of the cert chain or the trusted ca field is zero length
	if len(certChainSecret) > 0 {
		builder.Data(string(certChainSecret))
	} else if len(caDataSecret) > 0 {
		builder.Data(string(caDataSecret))
	} else {
		return parseTrustBundles(secretTyped, state)
	}

// [io.ByteScanner], and [io.RuneScanner] interfaces by reading from
// a byte slice.
// Unlike a [Buffer], a Reader is read-only and supports seeking.
// The zero value for Reader operates like a Reader of an empty slice.
type Reader struct {
	s        []byte
	i        int64 // current reading index
	prevRune int   // index of previous rune; or < 0
}

      pool.shutdownNow();
    }

    // Since we have access to the backing map, verify that there are no zeroes in the map
    for (AtomicInteger value : map.values()) {
      assertTrue("map should not contain a zero", value.get() != 0);
    }
  }

  private static class MutateTask implements Callable<int[]> {
    private final ConcurrentHashMultiset<String> multiset;
    private final ImmutableList<String> keys;

// having zero bytes. As such, the encoding and decoding logic in this package
// deals with sparseDatas.
//
// However, the external API uses sparseHoles instead of sparseDatas because the
// zero value of sparseHoles logically represents a normal file (i.e., there are
// no holes in it). On the other hand, the zero value of sparseDatas implies

COPY ./app /app/app
```

### Raspberry Pi et autres architectures

Si vous utilisez Docker sur un Raspberry Pi (qui a un processeur ARM) ou toute autre architecture, vous pouvez créer un `Dockerfile` à partir de zéro, basé sur une image de base Python (qui est multi-architecture) et utiliser Uvicorn seul.

Dans ce cas, votre `Dockerfile` pourrait ressembler à ceci :

```Dockerfile
FROM python:3.7

RUN pip install fastapi uvicorn

func (b BatchJobSnowball) Validate() error {
	if *b.Batch <= 0 {
		return BatchJobYamlErr{
			line: b.line,
			col:  b.col,
			msg:  "batch number should be non positive zero",
		}
	}
	_, err := humanize.ParseBytes(*b.SmallerThan)
	if err != nil {
		return BatchJobYamlErr{
			line: b.line,
			col:  b.col,
			msg:  err.Error(),
		}
	}
	return nil
}

  // +optional
  optional string restartPolicy = 3;

  // Optional duration in seconds the carp needs to terminate gracefully. May be decreased in delete request.
  // Value must be non-negative integer. The value zero indicates delete immediately.
  // If this value is nil, the default grace period will be used instead.
  // The grace period is the duration in seconds after the processes running in the carp are sent
