🕒 17:55–19:15
🏷️ Labels: Google Cloud, App Engine, Deployment, Logging, Flask, Python
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal: The session aimed to address and resolve multiple deployment and logging issues encountered on Google Cloud Platform (GCP), specifically focusing on Google App Engine and Flask applications.

Key Activities:

  1. Deployment Error Resolution: A comprehensive guide was followed to resolve deployment errors on Google App Engine, including steps to retry deployments, check project configurations, verify quotas, and review GCP logs.
  2. Integration of Google Cloud Logging: Instructions were provided for integrating Google Cloud Logging with Flask applications, addressing configuration issues related to the ‘ENV’ variable and logging function definitions.
  3. YAML Syntax Correction: Addressed syntax errors in the app.yaml file for GCP deployment, providing correct formatting and example structures.
  4. Entrypoint Configuration Troubleshooting: Troubleshooting steps were outlined for resolving syntax errors in App Engine entrypoint configurations, focusing on command format and function definitions.
  5. Filesystem Error Solutions: Solutions were provided for handling OSError related to read-only filesystem issues in Google Cloud App Engine, including changing log file locations and using Google Cloud Logging.
  6. File Handling and Permissions: Reflections on common file handling and permissions issues in GCP’s App Engine environment were documented, along with quick fixes and long-term solutions.
  7. Logger Initialization Diagnosis: Diagnosed an AttributeError related to a NoneType logger object in Python applications, providing potential causes and fixes.

Achievements:

  • Successfully resolved deployment and logging issues on Google Cloud Platform.
  • Improved understanding and configuration of Google Cloud Logging with Flask.
  • Enhanced error handling and troubleshooting skills for GCP deployments.

Pending Tasks:

  • Further exploration of object-oriented design for evaluators in Python applications, focusing on creating a base Evaluator class and subclasses for different models and feedback styles.
  • Implementing the updated design for Evaluator objects based on specific configurations such as environment variables.
