Docker for Mac을 사용하여 여러 Android 터미널과 병렬로 ADB를 사용하여 작업 수행

자기가 쓴 쪽지.
Docker for Mac으로 컨테이너에서 호스트 옆으로 연결된 Android 장치adb 방법
https://qiita.com/YusukeIwaki/items/5d31c10bc9bfe6d62845
Docker 컨테이너 두 개에서 터미널 두 개까지 ADB 연결을 하는 것을 조금 발전시키고 싶습니다.

-s 옵션과 유사한 환경 변수 ANDROID_SERIAL

일반적으로 여러 터미널을 PC에 삽입하는 경우 adb -s E32094823 shell 처럼 장치 직렬 ID를 -s로 많이 지정합니다.Docker로 이걸 하고 싶은데 가능하면 환경 변수로 하고 싶어요.

$ adb
Android Debug Bridge version 1.0.41
Version 29.0.1-5644136
Installed as /Users/yusuke-iwaki/Library/Android/sdk/platform-tools/adb

global options:
 -a         listen on all network interfaces, not just localhost
 -d         use USB device (error if multiple devices connected)
 -e         use TCP/IP device (error if multiple TCP/IP devices available)
 -s SERIAL  use device with given serial (overrides $ANDROID_SERIAL)
 -t ID      use device with given transport id
 -H         name of adb server host [default=localhost]
 -P         port of adb server [default=5037]
 -L SOCKET  listen on given socket for adb server [default=tcp:localhost:5037]

-s SERIAL use device with given serial (overrides $ANDROID_SERIAL)오!?
ANDROID_SERIAL?
android.googlesource.com/platform/system/core/+/master/adb/client/commandline.cpp

    // If none of -d, -e, or -s were specified, try $ANDROID_SERIAL.
    if (transport_type == kTransportAny && serial == nullptr) {
        serial = getenv("ANDROID_SERIAL");
    }

만약 -s에 아무것도 지정되지 않았다면 getenv("ANDROID_SERIAL")로 대입했기 때문에 -s와 같은 효과가 있었다.

docker-compose에서

docker-compose.yml

version: "3"
services:
  workspace_hogeperia:
    image: your_own/adb
    command: adb logcat
    environment:
      - ANDROID_SERIAL=CB1A2B3C45

  workspace_fugafone:
    image: your_own/adb
    command: adb logcat
    environment:
      - ANDROID_SERIAL=X51223098765

이런 느낌으로 환경 변수로 나누면 docker-compose up

두 용기 중 두 개adb logcat를 병행해서 실행할 수 있다.

그나저나 Appium은 용이 아니에요.

adb를 직접 사용하는 상황이라면 이해하기 쉽지만 Appium처럼 내부에서adb를 포장하는 라이브러리를 사용하는 경우에는 주의해야 한다.

appium이 내부 포장adb에서 무엇을 하기 때문에 ANDROID_Serial을 솔직하게 읽지 않았습니다.

desired cap의 udid 매개 변수에 환경 변수를 명확하게 추가한 ANDROID_SERIAL에 가입하여 이런 일을 할 필요가 있다

appium의 구조는 몰래 내부에서 실행adb forward하고 맥 측의 포트를 연결하여 안드로이드 장치 측의 서버에 명령을 전송하기 때문에 병행 동작을 위해 포트 번호를 틀리게 해야 한다

용기마다 desired cap을 바꾸는 시스템포트 매개 변수

　
내부에adbforward를 만들면 확실히 그렇게 생각한다는 말을 듣지만, 소스를 보기 전에는 눈치채지 못했다.
appium/appium-espresso-driver｜lib/driver.js

    // set up the modified espresso server etc
    this.initEspressoServer();
    // Further prepare the device by forwarding the espresso port
    logger.debug(`Forwarding Espresso Server port ${DEVICE_PORT} to ${this.opts.systemPort}`);
    await this.adb.forwardPort(this.opts.systemPort, DEVICE_PORT);

appium/appium-uiautomator2-driver｜lib/driver.js

    // set up the modified UiAutomator2 server etc
    await this.initUiAutomator2Server();

    // Further prepare the device by forwarding the UiAutomator2 port
    logger.debug(`Forwarding UiAutomator2 Server port ${DEVICE_PORT} to ${this.opts.systemPort}`);
    await this.adb.forwardPort(this.opts.systemPort, DEVICE_PORT);

이런 느낌이라 가벼운 타구를 봐도 포트 쟁탈을 눈치채기 어렵다.
