# 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
> [!NOTE]
> 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](file:///c:/Users/kumar/Downloads/Advanced%20Speech-to-Text%20&%20Text-to-Speech/backend/Dockerfile)
- Multi-stage Dockerfile.

#### [NEW] [docker-compose.yml](file:///c:/Users/kumar/Downloads/Advanced%20Speech-to-Text%20&%20Text-to-Speech/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/`.
