はじめに

App Service においてリモートビルドが有効な場合には、SCM サイトである kudu (App Service On Linux の場合は Kuduliteコンテナ)上で、Oryx を用いたリモートビルドが行われます。

この記事では、App Service On Linux Python アプリケーションを題材に、デプロイおよび、リモートビルドがどのように実行されているのかを確認します。

ローカルビルドについては以下で記載しています。

Node.js ランタイムのデプロイについては以下で記載しています。

TL;DR

App Service On Linux Python リモートビルドでは Oryx が動作します。
- Python ランタイムのダウンロードのために https://oryx-cdn.microsoft.io への通信が発生します。
- Pip モジュールインストールのために、https://pypi.org 、https://files.pythonhosted.org への通信が発生します。
Kudu コンテナ上において、Oryx(builder) によってビルドされたアプリケーションモジュールは /home/site/wwwroot/output.tar.gz として保存されます。
- その時のビルド情報は、/home/site/wwwroot/oryx-manifest.toml に記載されている。
App コンテナ上において、コンテナ起動時には Oryx(script generator) によって、スタートアップスクリプトが作成され、/home/site/wwwroot/output.tar.gz は、アプリケーションコンテナの /tmp 配下に展開されて実行されます。

題材

題材としては以下のチュートリアルに沿って　Django アプリをデプロイしてみます。

「1 - サンプルアプリケーション」まで進めてローカル環境で動作するようにしておきます。
プロジェクトルートには .venv が存在し、pip モジュールがインストールされた状態となっています。

また、まだ Azure 上にはデプロイしていないため　/home/site/wwwroot 配下は空のまま。/tmp 配下にも oryx ディレクトリは存在しません。（同じApp Service Plan で別のアプリでリモートビルドを利用している場合は既に存在している場合があります。)

App Service On Linux Python におけるリモートビルド

Python 環境においてリモートビルドを有効にする場合、アプリの設定 SCM_DO_BUILD_DURING_DEPLOYMENT が 1(または true) に設定されている必要があります。

VS Code 機能拡張を用いてデプロイする場合の Tips

VS Code 機能拡張を用いてデプロイする場合、zip デプロイが用いられることになりますが、デプロイの最適化をよしなにやってくれます。

上記ダイアログで Yes を選択すると、プロジェクト内に .vscode/settings.json と .deployment ファイルが作成されます。仕組みとしては Node.js 版での記事と同じです。

Zip デプロイの実行

VS Code の output パネルの出力は以下のようになります。

11:39:18 AM python-remote-build: Zip package size: 2.16 MB までは、VSCode(クライアント側)の処理となり、zip ファイルを作成したりする処理となります。

.vscode/settings.json に記載の appService.zipIgnorePattern に沿ってローカルビルド/実行時に必要だった pip モジュールなどは zip に含めないように作成されています。
Pythonのコード自体はわずかですが、サンプルプロジェクトには static/bootstrap が含まれているのでそれが影響して 2.16 MB となっています。

11:39:18 AM python-remote-build: Fetching changes. 以降が Kudu 上での処理となります。

VS Code によるリクエストは Zip パッケージを送信する POST と、デプロイステータス確認の GET が行われたことがわかります。
ここでは POST_api-zipdeploy_202.xml と、Background_POST_api-zipdeploy_pending.xml に着目します。

POST_api-zipdeploy_202.xml

POST_api-zipdeploy_202_1s.xml では以下のことがわかります。

api/zipdeploy?author=ms-azuretools-vscode&deployer=ms-azuretools-vscode&isAsync=true&trackDeploymentId=trueに対してリクエストが行われたこと
リクエスト内容から /tmp/zipdeploy/ca6d6728-ef21-43fd-811e-af4506d2fc8c.zip を保存したこと、
/api/zipdeploy はisAsync=true で呼び出されたため、Start deployment in the background 非同期処理が開始されたこと
ステータスコードは 202 を返却したこと

上記 Oryx 起動コマンドでは --log-file /tmp/build-debug.log および、| tee /tmp/oryx-build.log と 2 つのログファイル作成が行われています。

/tmp/oryx-build.log

Oryx によるアプリケーションのビルド処理全体は、/tmp/oryx-build.log に出力されています。
このログからは、Oryx によるDetect および Build 処理が行われたことがわかります。
その結果、Pythonランタイムの取得とpip install 等の処理行われています。

Pyhon 環境におけるビルドの詳細は下記に記載されています。

Build
The following process is applied for each build.

Run custom command or script if specified by PRE_BUILD_COMMAND or PRE_BUILD_SCRIPT_PATH.

Create python virtual environment if specified by VIRTUALENV_NAME.

Run python -m pip install --cache-dir /usr/local/share/pip-cache --prefer-binary -r requirements.txt if requirements.txt exists in the root of repo or specified by CUSTOM_REQUIREMENTSTXT_PATH.

Run python setup.py install if setup.py exists.

Run python package commands and determine python package wheel.

If manage.py is found in the root of the repo manage.py collectstatic is run. However, if DISABLE_COLLECTSTATIC is set to true this step is skipped.

Compress virtual environment folder if specified by compress_virtualenv property key.

Run custom command or script if specified by POST_BUILD_COMMAND or POST_BUILD_SCRIPT_PATH.

このタイミングで pip install が行われているため、Kudu コンテナから https://pypi.org 、https://files.pythonhosted.org など、requirements.txt に記載のないように基づいた通信が発生します。

VNet 統合時においては、Outbound の NSG でインターネット宛ての通信をブロックしている場合ビルドに失敗することになります。

/tmp/build-debug.log

/tmp/build-debug.log にはランタイム取得時のデバッグログなどが含まれています。
ストレージアカウントと見受けられる https://oryx-cdn.microsoft.io からファイル取得していることがわかります。

Network Dependencies
When using App Service with a Virtual Network or an App Service Environment, you will need to allow outbound access from the webapp to oryx-cdn.microsoft.io on port 443. oryx-cdn.microsoft.io hosts the Oryx packages corresponding to each SDK language and version. If this network dependency is blocked, then App Service will not be able to build your application using Oryx.

この Network 依存があるため VNet 統合時においては、Outbound の NSG でインターネット宛ての通信をブロックしている場合ビルドに失敗することになります。

リモートビルドの成果物

リモートビルドをした結果どのような状況になるのかを確認します。
Kudu FileManager から確認すると /home/site/wwwroot 配下には以下の 3 つのファイルが生成されています。

.ostype
oryx-manifest.toml
output.tar.gz
