Packing does not work with `poetry`

We use poetry to manage our dependencies. When we use in our workflows like that:

    - name: Upload Function
      uses: Azure/functions-action@v1
      with:
        app-name: ${{ inputs.function_app_name }}
        package: ${{ inputs.function_directory }}
        publish-profile: ${{ steps.pubprofile.outputs.publish_profile_xml }}
        scm-do-build-during-deployment: true
        enable-oryx-build: true

we encounter the following error:

I also found this two issue:

• Cannot run pip during pre-build command microsoft/Oryx#1370 but the suggested fix of setting the PRE_BUILD_COMMAND env.var. did not work.
• Deploy function app to Azure failed with error python3.9: bad interpreter: No such file or directory microsoft/Oryx#1769 which seems to be stale without any suggested fix.

Hi, I just made a workflow deploying a python flask app as an azure function, using poetry.
Here is an excerpt, hope it helps!

env:
  AZURE_FUNCTIONAPP_NAME: 'my_name'   # set this to your function app name on Azure
  AZURE_FUNCTIONAPP_PACKAGE_PATH: '.'       # set this to the path to your function app project, defaults to the repository root
  PYTHON_VERSION: '3.8'                     # set this to the python version to use (e.g. '3.6', '3.7', '3.8')
  POETRY_VERSION: '1.7.1'                     # set this to the python version to use (e.g. '3.6', '3.7', '3.8')


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

    - name: Setup Python ${{ inputs.PYTHON_VERSION }} Environment
      uses: actions/setup-python@v4
      with:
        python-version: ${{ inputs.PYTHON_VERSION }}

    - name: 'Set up poetry'
      uses: abatilo/actions-poetry@v2
      with:
        poetry-version: ${{ inputs.POETRY_VERSION }}
    
    - name: 'Resolve Project Dependencies Using Poetry'
      shell: bash
      run: |
        pushd './${{ inputs.AZURE_FUNCTIONAPP_PACKAGE_PATH }}'
        poetry export --format requirements.txt --output requirements.txt
        pip install -r requirements.txt --target=".python_packages/lib/site-packages"
        popd

    - name: Log into Azure

    - name: 'Run Azure Functions Action'
      uses: Azure/functions-action@v1
      id: fa

@GodVenn thank! But since MS was not helpful in that regard (honestly and sadly no surprise 😞) we settled on the following workaround:

jobs:
  func:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout repository
      uses: actions/checkout@v4
      with:
        ref: ${{ inputs.commit_sha }}

    - name: Install dependencies and login to Azure CLI
      uses: ./.github/actions/prepare-runner
      with:
        azure-tenant-id: ${{ vars.AZURE_TENANT_ID }}
        azure-subscription-id: ${{ vars.AZURE_SUBSCRIPTION_ID }}
        azure-client-id: ${{ vars.AZURE_CLIENT_ID }}

# interesting stuff starts here:

    - name: Install poetry
      uses: abatilo/actions-poetry@v2
# optionally select a version:
      #      with:
      #        poetry-version: # default=latest

    - name: Make Oryx happy with requirements.txt
      working-directory: ${{ inputs.function_directory }}
      run: |
        poetry export --without=test --without-hashes --format=requirements.txt > requirements.txt

    - name: Upload Function
      uses: Azure/functions-action@v1
      with:
        app-name: ${{ inputs.function_app_name }}
        package: ${{ inputs.function_directory }}
        scm-do-build-during-deployment: true
        enable-oryx-build: true

I seems like the Oryx builder which the Azure/functions-action@v1 is using does the pip install itself. I complains if its not finding a requirements.txt, which gets fixed by exporting with poetry. Feel free to mix and match our solutions.

[GodVenn]

@paulschroeder-tomtom Yeah, that's essentially the same workaround we have!

[GPetrites]

Very strange because App Services, which also uses Oryx, works correctly with poetry
