**컨테이너**, Docker, Kubernetes에 대한 일부 내용이 아직은 잘 이해되지 않아도 괜찮습니다.

다음 장에서 컨테이너 이미지, Docker, Kubernetes 등을 더 설명하겠습니다: [컨테이너에서 FastAPI - Docker](docker.md).

## 시작 전 사전 단계 { #previous-steps-before-starting }

애플리케이션을 **시작하기 전에** 어떤 단계를 수행하고 싶은 경우가 많습니다.

예를 들어 **데이터베이스 마이그레이션**을 실행하고 싶을 수 있습니다.

하지만 대부분의 경우, 이런 단계는 **한 번만** 수행하고 싶을 것입니다.

그래서 애플리케이션을 시작하기 전에 그 **사전 단계**를 수행할 **단일 프로세스**를 두고 싶을 것입니다.

// `cond_output`, `body_outputs`, and `name`. The `body_outputs` buffer will be
// allocated to size `ninputs`. The caller should build `cond_graph` and
// `body_graph` starting from the inputs, and store the final outputs in
// `cond_output` and `body_outputs`.
//
// If `status` is OK, the caller must call either TF_FinishWhile or

## Etapas anteriores antes de começar { #previous-steps-before-starting }

Há muitos casos em que você deseja executar algumas etapas **antes de iniciar** sua aplicação.

Por exemplo, você pode querer executar **migrações de banco de dados**.

		size = 0
	}
	tw.curr = &regFileWriter{tw.w, size}
	tw.pad = blockPadding(size)
	return nil
}

// AddFS adds the files from fs.FS to the archive.
// It walks the directory tree starting at the root of the filesystem
// adding each file to the tar archive while maintaining the directory structure.
func (tw *Writer) AddFS(fsys fs.FS) error {

			return false // Regions cannot overlap and must be in order
		}
		pre = cur
	}
	return true
}

// alignSparseEntries mutates src and returns dst where each fragment's
// starting offset is aligned up to the nearest block edge, and each
// ending offset is aligned down to the nearest block edge.
//
// Even though the Go tar Reader and the BSD tar utility can handle entries

    assertThat(countFrames(logs, "FINE: >> 0x00000003     3 DATA          END_STREAM"))
      .isEqualTo(1)
  }

  @Test
  fun pingsTransmitted() {
    // Ping every 500 ms, starting at 500 ms.
    client =
      client
        .newBuilder()
        .pingInterval(Duration.ofMillis(500))
        .build()

    // Delay the response to give 1 ping enough time to be sent and replied to.

<p>
Most hand-written assembly files do not include the full package path
in symbol names, because the linker inserts the package path of the current
object file at the beginning of any name starting with a period:
in an assembly source file within the math/rand package implementation,
the package's Int function can be referred to as <code>·Int</code>.
