在 Azure 上為 Azure Python 函數設置 CI/CD 管道

Question

我正在嘗試使用 Azure DevOps Pipeline 為 Azure Python 函數構建 CI/CD 管道。 我主要嘗試遵循以下教程： https : //medium.com/bb-tutorials-and-thoughts/how-to-build-ci-cd-for-python-azure-functions-using-azure-devops- 7087a76e535b

但我遇到的一個問題是，在同一個存儲庫中，我有多個 Azure Functions 的代碼。 例如，

| - app 
| - microservices
|    | - azure_func1
|    | - azure_func2
|    | - azure_func3
|    | - azure_func4

在每個 Azure Function 文件夾中，我都有必要的文件（例如 host.json、proxies.json、requirements.txt 等）。 設置管道時，我似乎找不到允許我指定構建管道從哪個目錄獲取代碼並將其構建到 Azure Artifacts 的字段。

請指教！

Azure 函數應用程序有多個配置來管理將應用於所有函數的函數應用程序實例，這里的 host.json 是放置所有這些配置的元數據文件。

host.json 中與綁定相關的配置同樣適用於函數應用中的每個函數。

在 host.json 中，我們可以指定可以應用設置的函數數量，以便特定配置只考慮這些函數。 如果此數組為空，則這將應用於函數 app 中的整個函數。

{
    "functions": [ "function1", "function2" ]
}

以下是示例 host.json：

{
    "version": "2.0",
    "aggregator": {
        "batchSize": 1000,
        "flushTimeout": "00:00:30"
    },
    "extensions": {
        "blobs": {},
        "cosmosDb": {},
        "durableTask": {},
        "eventHubs": {},
        "http": {},
        "queues": {},
        "sendGrid": {},
        "serviceBus": {}
    },

        "id": "Microsoft.Azure.Functions.ExtensionBundle",

            "samplingSettings": {
              "isEnabled": true,
              "maxTelemetryItemsPerSecond" : 20,
              "evaluationInterval": "01:00:00",
              "initialSamplingPercentage": 100.0,

            "enableLiveMetrics": true,
            "enableDependencyTracking": true,
            "enablePerformanceCountersCollection": true,            
            "httpAutoCollectionOptions": {
                "enableHttpTriggerExtendedInfoCollection": true,
                "enableW3CDistributedTracing": true,
                "enableResponseHeaderInjection": true
            },
            "snapshotConfiguration": {
                "agentEndpoint": null,
                "captureSnapshotMemoryWeight": 0.5,

                "isExceptionSnappointsEnabled": false,
                "isLowPrioritySnapshotUploader": true,
                "maximumCollectionPlanSize": 50,
                "maximumSnapshotsRequired": 3,
                "problemCounterResetInterval": "24:00:00",
                "provideAnonymousTelemetry": true,
                "reconnectInterval": "00:15:00",
                "shadowCopyFolder": null,
                "shareUploaderProcess": true,
                "snapshotInLowPriorityThread": true,
                "snapshotsPerDayLimit": 30,
                "snapshotsPerTenMinutesLimit": 1,
                "tempFolder": null,
                "thresholdForSnapshotting": 1,
                "uploaderProxy": null
            }
        }
    },
    "managedDependency": {
        "enabled": true
    },
    "retry": {
      "strategy": "fixedDelay",
      "maxRetryCount": 5,
      "delayInterval": "00:00:05"
    },
    "singleton": {
      "lockPeriod": "00:00:15",
      "listenerLockPeriod": "00:01:00",
      "listenerLockRecoveryPollingInterval": "00:01:00",
      "lockAcquisitionTimeout": "00:01:00",
      "lockAcquisitionPollingInterval": "00:00:03"
    },
    "watchDirectories": [ "Shared", "Test" ],
    "watchFiles": [ "myFile.txt" ]
}

此外，如果我們想根據您的要求禁用不觸發的功能，我們可以在 local.settings.json 中添加值"AzureWebJobs.HttpExample.Disabled": true 。

示例如下：

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true", 
    "AzureWebJobs.HttpExample.Disabled": true
  }
}
