问题描述

使用Github Action，通过 Azure/functions-container-action@v1 插件来完成 yaml 文件的配置，并成功部署Function Image 的过程记录。

【Azure Developer】在Github Action中使用Azure/functions-container-action@v1配置_Azure

操作步骤

第一步：准备Function的镜像文件

如在VS Code中，通过Terminal(命令行窗口)，根据所使用的语言，创建或初始化DockerFile

func init --worker-runtime python --docker

# --docker 选项生成该项目的 Dockerfile，其中定义了适合用于 Azure Functions 和所选运行时的自定义容器 Python

执行后的效果为在Function 项目中添加Dockerfile文件。

【Azure Developer】在Github Action中使用Azure/functions-container-action@v1配置_docker_02

参考文档 -- 在 Linux 上使用自定义容器创建函数：https://docs.azure.cn/zh-cn/azure-functions/functions-create-function-linux-custom-image?tabs=in-process%2Cbash%2Cazure-cli&pivots=programming-language-python

第二步：上传镜像到ACR

首先，在本地启动Docker Desktop后，使用Docker build 生产镜像文件。

然后，登录ACR(Azure Container Registry ：Azure 容器注册表)。

命令示例如下：

## 本地生产Image文件
docker build --tag azurefunctionsimage:v1 .

## 登录Azure镜像库
docker login <your-registry-name>.azurecr.cn --username <your-registry-username>


## 设置tag，推送到ACR
docker tag azurefunctionsimage <your-registry-name>.azurecr.cn/azurefunctionsimage:v1

docker push <your-registry-name>.azurecr.cn/azurefunctionsimage:v1

参考文档 -- 向 Azure 容器注册表推送映像： https://docs.azure.cn/zh-cn/app-service/tutorial-custom-container?pivots=container-linux#push-the-image-to-azure-container-registry

第三步：配置用户标识

启用用户标识，主要就是为了能够让它有权限去访问ACR并且拉取镜像文件

1:创建用户标识：Create User Assigned Managed Identity - Microsoft Azure 由世纪互联运营

【Azure Developer】在Github Action中使用Azure/functions-container-action@v1配置_docker_03

2:在ACR中为用户标识赋予权限(Contributor or Reader)：分配 Azure 角色的步骤 https://docs.azure.cn/zh-cn/role-based-access-control/role-assignments-steps

【Azure Developer】在Github Action中使用Azure/functions-container-action@v1配置_docker_04

第四步：配置Github Action的 workflow yaml文件

Action的workflow文件中，有两段内容需要配置，一是设置用户标识，二是设置镜像路径。

第一段，修改Function App的设置

- name: Azure App Service Settings
      uses: Azure/appservice-settings@v1
      with:
        # Name of the Azure Web App
        app-name: fun-name 
        general-settings-json: '{"acrUseManagedIdentityCreds": "true", "acrUserManagedIdentityID": "user managed identity id xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"}'

第二段，配置Image 路径

- name: 'Run Azure Functions Container Action'
      uses: Azure/functions-container-action@v1
      id: fa
      with:
        app-name: fun-name
        image: youracrname.azurecr.cn/imagename:version

以上配置与 Azure Funciton 门户上 Development Center 的设置对比关系如下：

【Azure Developer】在Github Action中使用Azure/functions-container-action@v1配置_docker_05

参考的github上yaml文件内容：https://github.com/Azure/actions-workflow-samples/tree/master/FunctionApp 和 https://github.com/Azure/actions-workflow-samples/blob/master/FunctionApp/linux-container-functionapp-on-azure.yml

修改后的yaml内容：

# Action Requires
# 1. Setup the AZURE_CREDENTIALS secrets in your GitHub Repository
# 2. Setup the REGISTRY_USERNAME secrets in your GitHub Repository
# 3. Setup the REGISTRY_PASSWORD secrets in your GitHub Repository
# 4. Replace REGISTRY, NAMESPACE, IMAGE, TAG in the following template with proper values
# 5. Add this yaml file to your project's .github/workflows/
# 6. Push your local project to your GitHub Repository

name: Linux_Container_Workflow

on: [push]

#on:
#  push:
#    branches:
#    - master

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    environment: dev
    steps:
    - name: 'Checkout GitHub Action'
      uses: actions/checkout@v3

    #- name: 'Login via Azure CLI'
    #  uses: Azure/login@v1.4.6
    #  with:
    #    creds: ${{ secrets.AZURE_CREDENTIALS }}
    #    environment: AzureChinaCloud
    #    #allow-no-subscriptions: true
    
    - name: 'set subscriptions'
      run: |
          az cloud set --name AzureChinaCloud
          az login -u your azure user name -p "password" 
          az account set --subscription "your subscription id"

    - name: 'Docker Login'
      uses: azure/docker-login@v1
      with:
        login-server: youracrname.azurecr.cn
        username: ${{ secrets.REGISTRY_USERNAME }}
        password: ${{ secrets.REGISTRY_PASSWORD }}
      

    # - name: 'Compose Customized Docker Image'
    #   shell: bash
    #   run: |
    #     # If your function app project is not located in your repository's root
    #     # Please change the path to your directory for docker build
    #     docker build . -t REGISTRY/NAMESPACE/IMAGE:TAG
    #     docker push REGISTRY/NAMESPACE/IMAGE:TAG


    - name: Azure App Service Settings
      uses: Azure/appservice-settings@v1
      with:
        # Name of the Azure Web App
        app-name: functionappname
        general-settings-json: '{"acrUseManagedIdentityCreds": "true", "acrUserManagedIdentityID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"}'

    - name: 'Run Azure Functions Container Action'
      uses: Azure/functions-container-action@v1
      id: fa
      with:
        app-name: functionappname
    #image: REGISTRY/NAMESPACE/IMAGE:TAG
        image: youracrname.azurecr.cn/azurefunctionimage:v1

    #- name: 'use the published functionapp url in upcoming steps'
    #  run: |
    #    echo "${{ steps.fa.outputs.app-url }}"

    - name: Azure logout
      run: |
        az logout
# For more information on GitHub Actions:
#   https://help.github.com/en/categories/automating-your-workflow-with-github-actions

以上操作完成后，即可上传workflow yaml文件到 .github/workflows/ 目录下。因为条件设置为 on: [push]，所以任何对代码库的push操作就会触发该workflow。

成功的效果图如本文最开始“问题描述”中的图片一致。

在Azure Function的log中，也能发现类似的Container启动日志：
