## Construir uma Imagem Docker para FastAPI { #build-a-docker-image-for-fastapi }

Okay, vamos construir algo agora! 🚀

Eu vou mostrar como construir uma **imagem Docker** para FastAPI **do zero**, baseada 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**

		}
		if !rule.Transition.IsDateNull() && rule.Transition.Date.Before(time.Now().UTC()) {
			return true
		}
		if !rule.Transition.IsNull() { // this allows for Transition.Days to be zero.
			return true
		}
	}
	return false
}

// ParseLifecycleConfigWithID - parses for a Lifecycle config and assigns
// unique id to rules with empty ID.

        byte[] data = new byte[] { 0x01, 0x02, 0x03, 0x04 };

        assertDoesNotThrow(() -> digest.update(data, 0, data.length));
    }

    @Test
    @DisplayName("Test update method with zero length")
    void testUpdateWithZeroLength() {
        SMB1SigningDigest digest = new SMB1SigningDigest(testMacSigningKey);
        byte[] data = new byte[] { 0x01, 0x02, 0x03, 0x04 };

		}
		if bytes.Equal(tr.blk[:], zeroBlock[:]) {
			return nil, nil, io.EOF // normal EOF; exactly 2 block of zeros read
		}
		return nil, nil, ErrHeader // Zero block and then non-zero block
	}

	// Verify the header matches a known format.
	format := tr.blk.getFormat()
	if format == FormatUnknown {
		return nil, nil, ErrHeader
	}

	var p parser
	hdr := new(Header)

        } else {
            SMBUtil.writeInt2(0, dst, dstIndex);
            SMBUtil.writeInt2(0, dst, dstIndex + 2);
            dstIndex += 4;
        }

        // one byte in buffer must be zero
        dst[dstIndex] = 0;
        dstIndex += 1;

        // Write SMB2_RDMA_TRANSFORM if using RDMA channel
        if (rdmaChannelInfo != null && channel == Smb2Constants.SMB2_CHANNEL_RDMA_V1) {

						return
					}
					asyncErrMu.Lock()
					if asyncErr == nil {
						asyncErr = err
					}
					asyncErrMu.Unlock()
				}
			}(name, header.FileInfo(), b)
			continue
		}

		// If zero or earlier modtime, set to current.
		// Otherwise the resulting objects will be invalid.
		if header.ModTime.UnixNano() <= 0 {
			header.ModTime = time.Now()
		}

		// Sync upload.
