tutorial

Understand how Docker containers communicate over networks and persist data with volumes. Learn bridge networking, service DNS, named volumes, and bind mounts with practical examples.

Learn Docker Compose from scratch. Define and run multi-container applications with a single docker-compose.yml file — app, database, and cache all together.

Learn how to write a Dockerfile from scratch. Understand every instruction, optimize layer caching, and use multi-stage builds to create lean production images.

Understand Docker images and containers from scratch. Learn what they are, how they differ, and run your first container with hands-on examples in under 30 minutes.

Master Docker networking and storage. Learn bridge, host, and overlay networks, container DNS, network security, volumes vs bind mounts, and production storage patterns with hands-on examples.

Master advanced Dockerfile techniques for production-ready images. Learn image size optimization, layer caching, multi-stage builds, security hardening, and language-specific best practices.

Master Kubernetes architecture, Pods, Deployments, Services, ConfigMaps, Secrets, and Namespaces. Learn to deploy and manage containerized applications on a Kubernetes cluster with hands-on examples.

Master Dockerfiles, multi-stage builds, and Docker Compose for multi-container applications. Learn to write production-ready Dockerfiles, optimize image sizes, and orchestrate full-stack apps.

Master device lifecycle management, OTA firmware updates, device shadows, configuration sync, and fleet management at scale in production IoT systems.

Master MQTT for production IoT systems. Covers topic design patterns, QoS trade-offs, session management, TLS/mTLS security, ACL authorization, broker clustering with EMQX and HiveMQ, and scaling to millions of connections.
