Docker Mastery

Master containerization with Docker for development and deployment.

Basic

Start with Docker basics

Understand containerization fundamentals — how containers differ from VMs, core Docker concepts, and getting Docker installed on your system.

Run and manage containers effectively — port mapping, environment variables, process management, and connecting containers together.

Build production containers

Build optimized Docker images with Dockerfiles — understand layers, follow best practices, and minimize image size for faster deployments.

Define multi-container applications with Docker Compose — services, networking, volumes, and environment configuration in a single YAML file.

Store, tag, and distribute Docker images through Docker Hub, private registries, and secure image management workflows.

Configure Docker networking — bridge networks, service discovery, port mapping, overlay networks, and DNS-based container communication.

Manage persistent data in Docker — named volumes, bind mounts, tmpfs, storage drivers, and backup strategies.

Debug containerized applications — view logs, exec into containers, inspect metadata, and monitor resource usage.
