Deploying Python to Azure App Service

注意：GitHub Enterprise Server 目前不支持 GitHub 托管的运行器。可以在 GitHub public roadmap 上查看有关未来支持计划的更多信息。

Introduction

This guide explains how to use GitHub Actions to build and deploy a Python project to Azure App Service.

Prerequisites

Before creating your GitHub Actions workflow, you will first need to complete the following setup steps:

创建 Azure 应用服务计划。

例如，可以使用 Azure CLI 创建新的应用服务计划：
Shell
```
az appservice plan create \
   --resource-group MY_RESOURCE_GROUP \
   --name MY_APP_SERVICE_PLAN \
   --is-linux
```
在上述命令中，将 MY_RESOURCE_GROUP 替换为� 原有的 Azure 资源组，将 MY_APP_SERVICE_PLAN 替换为应用服务计划的新名称。

有关使用 Azure CLI 的详细信息，请参阅 Azure 文档：
- 有关身份验证，请参阅“使用 Azure CLI 登录”。
- 如果需要创建新的资源组，请参阅“az group”。
Create a web app.

For example, you can use the Azure CLI to create an Azure App Service web app with a Python runtime:
Shell
```
az webapp create \
    --name MY_WEBAPP_NAME \
    --plan MY_APP_SERVICE_PLAN \
    --resource-group MY_RESOURCE_GROUP \
    --runtime "python|3.8"
```
In the command above, replace the parameters with your own values, where MY_WEBAPP_NAME is a new name for the web app.
配置 Azure 发布配置文件并创建 AZURE_WEBAPP_PUBLISH_PROFILE 机密。

使用发布配置文件生成 Azure 部署凭据。有关详细信息，请参阅 Azure 文档中的“生成部署凭据”。

在 GitHub 存储库中，创建一个名为 AZURE_WEBAPP_PUBLISH_PROFILE 的机密，其中包含发布配置文件的内容。要详细了解如何创建机密，请参阅“� 密的机密”。
Add an app setting called SCM_DO_BUILD_DURING_DEPLOYMENT and set the value to 1.
Optionally, configure a deployment environment. 环境用于描述常规部署目� �，例如 production、staging 或 development。当 GitHub Actions 工作流部署到某个环境时，该环境将显示在存储库的主页上。 � 可以使用环境来要求批准才能继续作业，限制哪些分支可以触发工作流，或限制对机密的访问。有关创建环境的详细信息，请参阅“使用环境进行部署”。

Creating the workflow

Once you've completed the prerequisites, you can proceed with creating the workflow.

The following example workflow demonstrates how to build and deploy a Python project to Azure App Service when there is a push to the main branch.

Ensure that you set AZURE_WEBAPP_NAME in the workflow env key to the name of the web app you created. If you use a version of Python other than 3.8, change PYTHON_VERSION to the version that you use.

如果配置了部署环境，请将 environment 的值更改为环境的名称。如果未配置环境，请� 除 environment 密钥。

# 此工作流使用未经 GitHub 认证的操作。
# 它们由第三方提供，并受
# 单独的服务条款、隐私政策和支持
# 文档。

# GitHub 建议将操作固定到提交 SHA。
# 若要获取较新版本，需要更新 SHA。
# 还可以引用� �记或分支，但该操作可能会更改而不发出警告。
