DOCKER LAB
Containerization & DevOps Journey
Welcome to my Docker Lab! This is where I document everything I learn about Docker and containerization.
From basic concepts to advanced orchestration, I'm building my skills one container at a time.
Docker has revolutionized how we build, ship, and run applications. Join me as I explore this powerful technology
and share my experiments, configurations, and lessons learned along the way.
Learning & Building
This is my experimental space for Docker. Containers will be created, destroyed, and recreated — that's the beauty of containerization!
Docker Resources & Labs
Introduction to Docker
Visual presentation covering Docker basics, core concepts, and why containerization matters in modern development.
Docker Installation & Setup
Step-by-step guide to installing Docker on different platforms and configuring your environment for optimal performance.
Working with Dockerfiles
Learn to create efficient Dockerfiles, understand layer caching, and build optimized container images from scratch.
Docker Compose
Multi-container applications made easy. Define and run complex applications with docker-compose.yml configurations.
Networking & Volumes
Deep dive into Docker networking modes and persistent data storage with volumes for stateful applications.
Real-World Projects
Hands-on labs deploying actual applications like databases, web servers, and full-stack apps using Docker.
Docker Security
Best practices for securing containers, managing secrets, and implementing security scanning in your workflow.
Kubernetes Basics
Taking the next step: container orchestration with Kubernetes for managing Docker containers at scale.
Docker Quick Tips
- Always use official images as base images when possible
- Keep your images small - use multi-stage builds
- Never store secrets in images - use Docker secrets or environment variables
- Use .dockerignore to exclude unnecessary files from your build context
- Tag your images properly for better version control
- Clean up unused containers and images regularly with docker system prune
- Test your containers locally before pushing to production
- Document your Dockerfile and docker-compose.yml files thoroughly
