Practical Docker, database, proxy, and development fundamentals for anyone getting started (or revisiting).

Our foundations tutorial covers essential concepts with copy-pasteable examples:

• Docker basics: containers, images, Dockerfile vs Compose
• Storage & networking: volumes, networks, environment variables
• Databases: Postgres, MySQL, Redis with Docker
• Reverse proxies: Nginx, HAProxy, Caddy, Traefik with HTTPS
• Development tools: Git branching, Linux CLI essentials
• Database patterns: SQL vs NoSQL comparison

Start with What is Docker to understand containers, then try Docker Compose Basics for multi-service apps.

For production deployments, check the proxy guides starting with Nginx for traditional reverse proxy setups, or Caddy for automatic HTTPS with minimal configuration.
