azure-pipelines.ymlでアプリ設定を追加・更新する

Azure Functionsのアプリ設定する例

AzureFunctionApp@2タスクのappSettingsは、文字列なので使い難い。。。

改行とか入ってしまうとダメ

appSettings - App settings
string.

Enter the application settings using the syntax -key value
(for example: -Port 5000 -RequestTimeout 5000 -WEBSITE_TIME_ZONE).
Enclose values that contain spaces in double quotes (for example: "Eastern Standard Time").

AzureAppServiceSettings@1タスクだと、JSONでしっかり書ける

以下は、azure-pipelines.ymlの抜粋

azure-pipelines.yml

variables:
  # Azure Resource Manager connection created during pipeline creation
  azureSubscription: "<DevOpsのService connections>"

  # リソースグループ名  
  resourceGroupName: "sample-group"

  # Function名
  functionAppName: "sample-func"

  # Agent VM image name
  vmImageName: "ubuntu-latest"

  # Working Directory
  workingDirectory: "$(System.DefaultWorkingDirectory)/"

  # 今回はAppConfigurationのエンドポイント
  appConfigurationEndpoint: "https://sample-app-config.azconfig.io"

  - stage: Deploy
    displayName: Deploy stage
    dependsOn: Build
    condition: succeeded()

    jobs:
      - deployment: Deploy
        displayName: Deploy
        environment: "development"
        pool:
          vmImage: $(vmImageName)

        strategy:
          runOnce:
            deploy:
              steps:
                - task: AzureFunctionApp@2
                  displayName: "Azure functions app deploy"
                  inputs:
                    azureSubscription: "$(azureSubscription)"
                    appType: functionAppLinux
                    resourceGroupName: $(resourceGroupName)
                    appName: $(functionAppName)
                    package: "$(Pipeline.Workspace)/drop/$(Build.BuildId).zip"
                    appSettings: |
                      [
                        {
                          "name": "HOGE",
                          "value": "VAR​"
                        },
                        {
                          "name": "POSTGRES_SERVER",
                          "value": "@Microsoft.AppConfiguration(Endpoint=$(appConfigurationEndpoint); Key=POSTGRES_SERVER)​"
                        }
                      ]

おわり

何故かAzureFunctionApp@2のappSettingsだとエラーになる
