🧩 Core Concepts

Docker provides a lightweight, reproducible and isolated environment for running applications. Key building blocks:

• Images — immutable filesystem snapshots
• Containers — running instances of images
• Networks — communication between containers
• Volumes — persistent storage
• Compose — multi‑container orchestration

---

🔧 Most Common Commands

# Build and start services
docker compose up -d --build

# View logs
docker compose logs -f

# List running containers
docker compose ps

# Enter a container shell
docker exec -it <container> sh
