こんにちは、MLBお兄さんこと松村です。
MLB はウインターミーティングも終わり、怒涛の移籍ラッシュが落ち着いたと思いきや、ソフトバンクホークスの千賀投手のニューヨーク・メッツとの5年契約が報道されました。
我がニューヨーク・ヤンキースは今のところ静かなオフとなっています。
このブログは2つのアドベントカレンダーの記事となっています。
GitHub 熱の高い最近の私ですが、先日 GitHub Japan で開催された「Go fast and robust with GitHub」で登壇をしてきました。イベントレポートについてはこちら。
イベント後半に行われた GitHub の CEO や VP との座談会セッションのなかで、GitHub Actions をローカル環境で動かすためのツール nektos/act が紹介されました。
twitter.comローカルでGitHub Actionsが動かせるOSSらしい。知らなかった！ #github #micughttps://t.co/PS4zlAGOSI
— Yuta Matsumura⚾MLBお兄さん (@tsubakimoto_s) 2022年12月6日
nektos/act とは、GitHub Actions をローカル環境で動かすためのオープンソースです。
GitHub 公式ツールではありませんが、CEO が紹介するくらいですので GitHub 内でも認知されているようです。
nektos/act を動かすには Docker が必要となります。Docker Desktop でも Docker Engine でも良いです。
なお、私は WSL2 Ubuntu にインストールしている Docker Engine で試しています。
インストールする
まずは nektos/act を Ubuntu に直接インストールします。
$ curl https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash

Dload Upload Total Spent Left Speed

nektos/act info checking GitHub for latest tag
nektos/act info found version: 0.2.34 for v0.2.34/Linux/x86_64
nektos/act info installed ./bin/act
$ act -h
Run GitHub actions locally by specifying the event name (e.g. `push`) or an action name directly.
Usage:
act [event name to run] [flags]

ワークフローを一覧表示する
とりあえずコマンドをいくつか実行してみます。
GitHub Actions 検証のために育てているリポジトリを使用します。

まー、たくさんありますね。ジョブの一覧を見ることができます。
コンテキストを見る
ワークフローのコンテキストをダンプしてみましょう。
コンテキストを見ると、ワークフローの実行者(actor)が nektos/act であることが分かります。

.NET アプリをビルドする
次に .NET のアプリケーションをビルドしてみます。
ワークフローの構成はこちらを参照してください。
SDK のインストール、プロジェクトのリストア・ビルド・テスト、いずれも問題なく実行できているようです。

Azure CLI を動かす
次に Azure CLI を使って、Azure にログインするワークフローを試します。
GitHub Actions から Azure に接続する場合、通常のサービスプリンシパルで認証する方法と、OIDC で認証する方法があります。
詳しくはこちらのドキュメントを参照してください。
GitHub Actions なら OIDC 一択ですが、nektos/act では OIDC は使えないためサービスプリンシパルで接続することとなります。
はじめ、方法が分かりませんでしたが、こちらのリポジトリを参考に実現することができました。
jobs: az_login: runs-on: ubuntu-latest steps: - name: Install Azure CLI if: github.actor == 'nektos/act' shell: bash run: | curl -sL https://aka.ms/InstallAzureCLIDeb | bash - name: Azure Login uses: Azure/login@v1 with: creds: ${{secrets.AZURE_CREDENTIALS}} - name: Show Azure regions run: az account list-locations - name: Az CLI Logout run: az logout
ここで actor が nektos/act の場合に限り、Azure CLI を独自にインストールすることで az コマンドを使用することができます。
なお AZURE_CREDENTIALS というシークレットが必要であるため、ファイルを用意しておきます。

devcontainer 定義を作成する
nektos/act はコンテナー環境で動作するということで、これは devcontainer の出番です。
devcontainer 自体がコンテナーで動きますが、Docker in Docker を構成することができるため、nektos/act を動かすこともできます。
devcontainer.json はこのように構成します。
{ "name": "Docker in Docker", "image": "mcr.microsoft.com/devcontainers/base:bullseye", "features": { "ghcr.io/devcontainers/features/common-utils:1": { "installZsh": "true", "upgradePackages": "false", "uid": "1000", "gid": "1000", "installOhMyZsh": "true", "nonFreePackages": "true" }, "ghcr.io/devcontainers/features/docker-in-docker:2": { "version": "latest", "enableNonRootDocker": "true", "moby": "true" }, "ghcr.io/dhoeric/features/act:1": {} } }
devcontainer 定義が作成できたということは、当然 GitHub Codespaces で動きます！
リポジトリ画面から Codespace を起動しましょう。これで、ブラウザだけで nektos/act によるワークフロー実装を行えるようになりました。
GitHub Actions 環境と全く一緒ではないでしょうが、GitHub Actions のデバッグをすべてオンラインでやるのは大変なので、こういったツールで少しでも効率化したいですね。
