Azure App Service (oryx) does not use the set startup command

Question

I want to deploy a Django DRF application to a azure App Service using artifacts (zip deployment) the artifact gets sucessfully uploaded from azure devops but the execution of the container fails since not all required packages are installed.

Since my python packages are managed with pipenv I use a custom startup.sh script to start my App Service the file looks like this:

python -m pip install --upgrade pip
pip install pipenv
pipenv install
pipenv run python manage.py migrate

pipenv run gunicorn --workers 2 --threads 4 --timeout 60 --access-logfile \
    '-' --error-logfile '-' --bind=0.0.0.0:8000 \
     --chdir=/home/site/wwwroot kez_backend.wsgi

and I set it in my CD pipeline like this:

but when I look at the logs of my App service the startup.sh script is not used and a custom one is create by oryx. Since oryx also creates a virtualenviroment and can't handle Pipfiles dependencys are missing.

Answer 1

I tried that using the env variables as described in the oryx documentation but it still gave me the same outcome

Initially, check the custom startup.sh script is included in the artifact that you deploy to the App Service. This file should be located in the root directory of the project.

To tell the App Service to run the startup.sh script at startup. Navigate to App Service dashboard, go to Configuration

• Under the General settings tab, check the Startup Command field. Set the value as like above. that command tells Azure to use custom startup.sh script located at the root of the app directory adjust the path if the script is elsewhere.

startup.sh:

#!/bin/bash

# Exit immediately if a command exits with a non-zero status
set -e

# Change to the app's directory (optional, depending on your project structure)
cd /home/site/wwwroot

# Install required dependencies
pip install -r requirements.txt

# Alternatively, install from Pipfile using pipenv (if your project uses Pipfile)
# pip install pipenv
# pipenv install --ignore-pipfile

# Install any missing packages explicitly
pip install python-decouple

# Run the application using Gunicorn with binding to port 8000
gunicorn --bind=0.0.0.0:8000 --timeout 600 myapp.wsgi:application

2024-10-23T22:34:40.255652449Z ModuleNotFoundError: No module named 'decouple'

• decouple package hasn’t been installed correctly in the environment. Add decouple to the Pipfile or requirements.txt, and confirm it is being picked up in the deployment package.

Check this logs cover installing dependencies, launching the application, and serving it with Gunicorn.
