Azure Appservice for Django fails with Azure Devops Pipeline

I have an appservice running on Azure in a Linux environment.

I try to associate it with a Azure Devops Pipeline so I can have CI/CD for the repositories & branches on Github.

I want the builds to occur on Azure Pipeline & Azure infrastructure, not Github Actions.

I have tried all other suggestions including following environment variables on App Service :

SCM_DO_BUILD_DURING_DEPLOYMENT=true

WEBSITE_NODE_DEFAULT_VERSION=~18

WEBSITE_RUN_FROM_PACKAGE=true

Here is the logs that I receive from the Kudu / Azure Devops Pipeline / AppService logs :

When I set includeRootFolder : true, build does not fail, logs : succesful but not working detailed logs 488

When I set includeRootFolder : false, build fails with the following, you can find the detailed logs here : failed detailed logs 489

Update : I am also trying with Github actions, the primary problem is : the zip file never arrives to Appservice from devops; either azure pipelines or github actions.

Solution

I have checked your Azure DevOps YAML Pipeline sample. It has some issues which will lead to the App service not able to work.

From the original log, it shows the error: ModuleNotFoundError: No module named 'project'. The cause of the issue is that the zip package doesn't contain the required python packages.

You can make the following changes to the Azure Pipeline YAML Sample:

1.You need to change the command to install python packages:

From

pip install -r requirements.txt

 pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt

In this case, the required packages will be installed to the correct folder and will be added to the zip pacakge.

2.You need to set the includeRootFolder field to false in ArchiveFiles@2 task.

If the value is set to true, it will include the parent folder : s to the zip package. This will cause the path issue in Web App. So we need to set the value to false.

Here is an example:

- task: ArchiveFiles@2
  displayName: 'Archive files'
  inputs:
    rootFolderOrFile: '$(System.DefaultWorkingDirectory)'
    includeRootFolder: false
    archiveType: zip
    archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
    replaceExistingArchive: true

Full Pipeline YAML sample:

trigger:
- $(feature-branch)

variables:
  azureServiceConnectionId: '-db5f-4993-91f8-85f3a75cb357'
  webAppName: 'project-app-development'
  vmImageName: 'ubuntu-latest'
  environmentName: 'project-app-development'
  projectRoot: $(System.DefaultWorkingDirectory)
  pythonVersion: '3.8'
  system.debug: true

stages:
- stage: Build
  displayName: Build stage
  jobs:
  - job: BuildJob
    pool:
      vmImage: $(vmImageName)
    steps:
    - task: UsePythonVersion@0
      inputs:
        versionSpec: '$(pythonVersion)'
      displayName: 'Use Python $(pythonVersion)'

    - script: |
        python -m virtualenv env
        source env/bin/activate
        python -m pip install --upgrade pip
        pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt
      workingDirectory: $(projectRoot)
      displayName: "Install requirements"

    - task: ArchiveFiles@2
      displayName: 'Archive files'
      inputs:
        rootFolderOrFile: '$(projectRoot)'
        includeRootFolder: false
        archiveType: zip
        archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
        replaceExistingArchive: true

    - upload: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
      displayName: 'Upload package'
      artifact: drop

- stage: Deploy
  displayName: 'Deploy Web App'
  dependsOn: Build
  condition: succeeded()
  jobs:
  - deployment: DeploymentJob
    pool:
      vmImage: $(vmImageName)
    environment: $(environmentName)
    strategy:
      runOnce:
        deploy:
          steps:
          - task: UsePythonVersion@0
            inputs:
              versionSpec: '$(pythonVersion)'
            displayName: 'Use Python version'

          - task: AzureWebApp@1
            displayName: 'Deploy Azure Web App : project-app-development'
            inputs:
              azureSubscription: $(azureServiceConnectionId)
              appName: $(webAppName)
              package: $(Pipeline.Workspace)/drop/$(Build.BuildId).zip

For more detailed info, you can refer to this doc: Use Azure Pipelines to build and deploy a Python web app to Azure App Service

Update:

Error: Package deployment using ZIP Deploy failed. Refer logs for more details.

Based on the error message, you can try the following methods:

1.Navigate to the App Settings in Azure Web App and set the variable: WEBSITE_RUN_FROM_PACKAGE to 1.

2.Navigate to App service --> Deployment Center, and click on the Disconnect button to disconnect the exist connections.

For example:

Then you can deploy the Azure Web App again and check the result.

Update1:

ModuleNotFoundError: No module named 'django'

I can reproduce the same issue in my Linux Web App.

To solve this issue, you can refer to the following steps:

Step1: Remove the variable: SCM_DO_BUILD_DURING_DEPLOYMENT in AppSettings of Azure Web App. In this case, it will directly used the existing packages in the zip package.

Step2: Change the pip install command:

From:

 pip install --target="./.python_packages/lib/site-packages" -r ./requirements.txt

To:

 pip install --target="./antenv/lib/python3.8/site-packages" -r ./requirements.txt

YAML Sample:

- script: |
   python -m venv antenv
   source antenv/bin/activate
   python -m pip install --upgrade pip
   pip install setup

   pip install --target="./antenv/lib/python3.9/site-packages" -r ./requirements.txt
  workingDirectory: $(projectRoot)
  displayName: "Install requirements"

From the log in the Azure App service, the default Python Path: /home/site/wwwroot/antenv/lib/python3.8.9/site-packages. We need to adjust the path in the package to meet the default Python Path.

Then you can run the pipeline to deploy the web app again.
