Document Enhancement Proposal: Retrieving error logs when azure-webapp deployment fails.

Overview

This enhancement provides a step-by-step guide to improve the deployment process for Flask and React applications on Azure Web App, addressing common challenges in managing dependencies and build steps. The proposed documentation enhancement focuses on activating Oryx to handle the build process, providing alternative deployment methods, and leveraging logs for troubleshooting. This guidance aims to streamline deployment for developers by clarifying each step and providing improved error handling.

Enhancement Details

This guide will enable users to:

• Activate Oryx build handling during deployment for applications with complex dependencies.
• Package and deploy the application manually using Azure CLI commands.
• Access deployment logs for troubleshooting.
• Implement enhanced Docker configuration for better error management.

Steps for Improved Flask/React Deployment on Azure Web App

1. Setting the App Setting for Oryx Activation

Add the SCM_DO_BUILD_DURING_DEPLOYMENT=true setting in Azure App Settings to activate Oryx for build handling during deployment.

2. Manual Packaging and Deployment

Instead of relying solely on az webapp up, manually package and deploy the application using the following steps:

zip -r app.zip .
az webapp deploy --resource-group <your_resource_group> --name <your_app_name> --src-path app.zip

3. Verify Dependencies

Ensure that all required dependencies are correctly listed in requirements.txt for Flask and package.json for React. Missing dependencies are a common cause of deployment failures.

4. Access and Monitor Deployment Logs

• Deployment processes produce logs in the /LogFiles directory on Azure, which contain standard output and error logs. Reviewing these logs can reveal stack traces or system errors.
• Enable log streaming to monitor logs live, providing real-time insights into any issues that arise during deployment.

Justification for Documentation Enhancement

Currently, the Azure documentation provides limited guidance on the specifics of deploying complex Flask and React applications with custom configurations, leaving developers to troubleshoot build and deployment issues without sufficient support. This enhancement fills that gap by offering a structured, example-based solution that addresses common deployment errors and includes robust error-handling configurations.

Conclusion
By following this enhanced guide, users can effectively manage the deployment process for Flask and React applications on Azure Web App, making use of Oryx, manual packaging, Docker enhancements, and log streaming for a smoother and more reliable deployment experience.

Reference

Why does deploying to azure web app fails with no apparent error? How can i retrieve better error logs to fix the issue?

This documentation update will improve user experience, reduce deployment errors, and enable faster troubleshooting for developers deploying web applications in enterprise environments.
