在 Azure 上为 Azure Python 函数设置 CI/CD 管道

Question

我正在尝试使用 Azure DevOps Pipeline 为 Azure Python 函数构建 CI/CD 管道。 我主要尝试遵循以下教程： https : //medium.com/bb-tutorials-and-thoughts/how-to-build-ci-cd-for-python-azure-functions-using-azure-devops- 7087a76e535b

但我遇到的一个问题是，在同一个存储库中，我有多个 Azure Functions 的代码。 例如，

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

在每个 Azure Function 文件夹中，我都有必要的文件（例如 host.json、proxies.json、requirements.txt 等）。 设置管道时，我似乎找不到允许我指定构建管道从哪个目录获取代码并将其构建到 Azure Artifacts 的字段。

请指教！

Azure 函数应用程序有多个配置来管理将应用于所有函数的函数应用程序实例，这里的 host.json 是放置所有这些配置的元数据文件。

host.json 中与绑定相关的配置同样适用于函数应用中的每个函数。

在 host.json 中，我们可以指定可以应用设置的函数数量，以便特定配置只考虑这些函数。 如果此数组为空，则这将应用于函数 app 中的整个函数。

{
    "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": {}
    },

                "enableHttpTriggerExtendedInfoCollection": true,
                "enableW3CDistributedTracing": true,

            },
            "snapshotConfiguration": {

                "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，如果我们想根据您的要求禁用不触发的功能，我们可以在 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
  }
}
