Docker for Developers

Master containerization and streamline your development workflow

Introduction

Docker has revolutionized how we build, ship, and run applications. By packaging your application with all its dependencies into containers, you ensure consistency across development, testing, and production environments. Say goodbye to "it works on my machine" problems!

This tutorial will take you from Docker basics to building multi-container applications. You'll learn how to create Dockerfiles, use Docker Compose, optimize images, and deploy containerized applications to the cloud.

Docker fundamentals and architecture

Installing Docker on your system

Creating your first Dockerfile

Building and running containers

Docker images and layers

Docker Compose for multi-container apps

Volumes and data persistence

Networking between containers

Multi-stage builds for optimization

Docker best practices and security

Key Concepts

Containers

Lightweight, portable units that package your application with all dependencies for consistent execution anywhere.

Images

Read-only templates used to create containers. Build once, run anywhere with guaranteed consistency.

Orchestration

Manage multiple containers with Docker Compose and prepare for production with orchestration tools.

CI/CD Integration

Integrate Docker into your continuous integration and deployment pipelines for automated workflows.
