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。
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。
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
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
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
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:
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:
