デプロイの自動化

VS Codeのタスクの作成

VS Code のタスク機能を使って、デプロイを自動化します。.vscode/tasks.jsonを作成します。

tasks.json

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Build WAR (WSL)",
      "type": "shell",
      "command": "bash -lc 'mvn -q -DskipTests=false clean package'",
      "options": { "cwd": "${workspaceFolder}" },
      "problemMatcher": []
    },
    {
      "label": "Stop Tomcat10 (only if running)",
      "type": "shell",
      "command": "bash -lc '[ \"$(systemctl is-active tomcat10)\" = \"active\" ] && sudo systemctl stop tomcat10'"
    },
    {
      "label": "Clean exploded webapp",
      "type": "shell",
      "command": "bash -lc 'sudo rm -rf /var/lib/tomcat10/webapps/servlet-demo'",
      "problemMatcher": []
    },
    {
      "label": "Deploy WAR to Tomcat (WSL)",
      "type": "shell",
      "command": "bash -lc 'sudo cp -f ${workspaceFolder}/target/servlet-demo.war /var/lib/tomcat10/webapps/servlet-demo.war'",
      "problemMatcher": []
    },
    {
      "label": "Start Tomcat10",
      "type": "shell",
      "command": "bash -lc 'sudo systemctl start tomcat10'"
    },
    {
      "label": "Restart Tomcat10",
      "type": "shell",
      "command": "bash -lc 'sudo systemctl restart tomcat10'"
    },
    {
      // まとめタスク：一括で「ビルド→停止→クリーン→デプロイ→起動」
      "label": "Deploy & Start (Tomcat10, WSL)",
      "dependsOn": [
        "Build WAR (WSL)",
        "Stop Tomcat10",
        "Clean exploded webapp",
        "Deploy WAR to Tomcat (WSL)",
        "Start Tomcat10"
      ],
      "dependsOrder": "sequence",
      "problemMatcher": []
    }
  ]
}

VS Codeの起動コマンドの登録

VS Code のデバッグで実行するコマンドを登録します。.vscode/launch.jsonファイルを作成します。

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "java",
      "name": "Attach to Tomcat10 (WSL)",
      "request": "attach",
      "hostName": "127.0.0.1",
      "port": 8000,
      "preLaunchTask": "Deploy & Start (Tomcat10, WSL)",
      "sourcePaths": [
        "${workspaceFolder}/src/main/java"
      ]
    }
  ]
}

sudoコマンドの設定変更

VS Code のタスクでsudoコマンドを複数回使います。パスワードを入力する必要がないように、/etc/sudoersファイルを修正します。 sudoersファイルはvisudoコマンドで修正します。

sudo visudo

%sudo   ALL=(ALL:ALL) NOPASSWD: ALL # 修正箇所
