Docker for Macを使って複数のAndroid端末に並列でADBで何かをする

Posted at

自分用メモ。

Docker for Mac でコンテナからホスト側に接続したAndroidデバイスにadbする方法
https://qiita.com/YusukeIwaki/items/5d31c10bc9bfe6d62845

を少し発展させて、２つのDockerコンテナから２つの端末にADB接続するようにしたい。

-s オプションと同様のことを実現する環境変数 ANDROID_SERIAL

普段、複数端末をPCにさしている場合などは adb -s E32094823 shell のように -sでデバイスシリアルIDを指定することが多い。これをDockerでやりたいわけだが、できればこういうのは環境変数で持たせたい。

$ 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)

お！？

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");
    }

-s で何も指定されていなかったら、 getenv("ANDROID_SERIAL") で代入しているので、やはり -s と同じ効果がありそうだ。

docker-composeで。

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

こんな感じで環境変数で分けておけば、 docker-compose up すれば

wo

２つのコンテナから２つの adb logcat が並列実行できたぞ、っと。

ちなみにAppiumは一筋縄ではいかない

adbを素で使うケースだとわかりやすいんだけど、Appiumのように内部でadbをラップしてるようなライブラリを使う場合には注意が必要。

  • appiumは内部でadbをラップしてなにかやっているので、ANDROID_SERIALを素直に読んでくれなかった。
    • 明示的にでdesired capのudidパラメータに環境変数のANDROID_SERIALを入れる、みたいなことをやる必要がある
  • appiumは、こっそり adb forward を内部で実行して、Mac側のポートをバインドしてAndroidデバイス側のサーバーにコマンドを転送する仕組みをしているので、並列動作させるにはポート番号をずらす必要がある
    • desired capのsystemPortパラメータをコンテナごとに変える必要がある

　

内部でadb forwardしているというのは、確かに言われてみたらそうだよなーとは思うんだけど、ソース見るまで自分は気づかなかった。

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);

systemPortを同じにしてしまった時のエラーログが

こんな感じなので、パット見でポートの取り合いになっているということにも気付きづらい。
