Bulletproof Deployment with Python & Docker
Moving a Laravel backend from local development to a production Docker image involves several "fragile" steps: swapping .env files, clearing logs, building frontend assets, and handling storage symlinks. One missed step means a broken deployment.

The Solution:
I wrote a comprehensive Python orchestration script to manage the Digi-Portal build pipeline:
-
State Management: The script automatically backups local storage folders and swaps local
.envconfigs for staging/production versions before the build starts. -
Unified Pipeline: In one command, it triggers
npm run build,docker build, anddocker save, ensuring the image is bundled as a portable.tarfile. -
Auto-Revert Logic: A critical feature—if the build fails, the script uses a
try...exceptblock to automatically restore the local environment and fix the.envfiles, preventing "broken" local dev states. -
Cleanup: It clears Laravel logs and old image artifacts to keep the build environment lean.
The Result:
A "One-Click" deployment process that eliminates human error. The build is reproducible, the environment is always protected, and the iteration speed for the backend has doubled.
