🧩 1. Split your Compose setup

You already have docker-compose.yml, which could be your base file, and then:

• docker-compose.dev.yml for development
• docker-compose.prod.yml for production

Each override or extend the base. For example:

docker-compose.yml (base)

version: "3.7"

services:
  web:
    build: .
    container_name: ca.web
    ports:
      - "8018:8000"
    command: gunicorn app.wsgi:application

docker-compose.dev.yml

version: "3.7"

services:
  web:
    volumes:
      - .:/usr/src/
    command: tail -f /dev/null
    environment:
      - DEBUG=True

docker-compose.prod.yml

version: "3.7"

services:
  web:
    volumes: []  # Disable bind mount
    restart: unless-stopped
    environment:
      - DEBUG=False

---

🚀 2. Run with a specific config

Use the -f flag to load specific files:

🛠 Development:

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up

🚢 Production:

docker-compose -f docker-compose.yml -f docker-compose.prod.yml up --build -d

You can chain multiple files; Docker will merge them in order (later files override earlier ones).

---

🧼 Optional: Clean up or streamline

To simplify running dev vs prod, create aliases or scripts:

run-dev.sh

#!/bin/bash
docker-compose -f docker-compose.yml -f docker-compose.dev.yml up

run-prod.sh

#!/bin/bash
docker-compose -f docker-compose.yml -f docker-compose.prod.yml up --build -d

Make them executable:

chmod +x run-dev.sh run-prod.sh

---

✅ Summary

• Use docker-compose.yml as your base.
• Create docker-compose.dev.yml and docker-compose.prod.yml to override volume, env, command, etc.
• Use -f to specify the config when you run Compose.

Let me know if you'd like a template setup or want to include things like PostgreSQL or static file collection for prod.
