Implementation Plan - Phase 17.2: Docker Containerization

Goal Description

Containerize the backend application to ensure consistent environments across development and production. We will create a production-ready Dockerfile and a docker-compose.yml for easy orchestration of the API and services (Redis).

User Review Required

We will create backend/Dockerfile.

• Base image: python:3.10-slim (Small footprint).
• Multi-stage build (Builder pattern) to keep image small.
• Install system dependencies (ffmpeg is large, so we might need a specific strategy or just install it).
• Expose port 8000.

We will also create docker-compose.yml at the root.

• Service backend: build context ./backend.
• Service redis: image redis:alpine.

Proposed Changes

Configuration

[NEW] backend/Dockerfile

• Multi-stage Dockerfile.

[NEW] docker-compose.yml

• Define services for local development/deployment.

Verification Plan

Automated Verification

• Run docker-compose config to validate syntax.
• (Optional) Build the image: docker build -t voiceforge-backend backend/.
