Docker
Transcript-derived Docker fundamentals, from images and containers to Compose, volumes, networking, and reproducible delivery.
Introduction to Docker
Foundations: what Docker is, why it became essential, and how it fixes environment drift in teams.
Docker Installation
Install and verify Docker correctly so the CLI-daemon pipeline is stable before development begins.
Docker Commands
Operational command fluency for image lifecycle, container lifecycle, and runtime diagnostics.
Docker Image Layers
Layering mechanics, cache invalidation behavior, and performance implications for build pipelines.
Port Binding
Host-to-container port mapping, listener behavior, and reliable service exposure.
Troubleshoot Commands and Logs
Structured troubleshooting workflow using logs, inspect, exec, and dependency validation.
Docker vs Virtual Machine
Architectural comparison: isolation model, overhead profile, startup behavior, and deployment fit.
Developing with Docker
Practical local development loops with containers, mounts, env config, and service parity.
Docker Compose
Declarative orchestration for multi-container application stacks and dependency coordination.
Dockerizing Our Application
Convert your own app into a robust image with deterministic dependencies and production-ready runtime contract.
Publishing Images to Docker Hub
Registry publishing, tag governance, release promotion, and rollback safety.
Docker Volumes
Persistent storage strategy with named volumes, anonymous volumes, bind mounts, and lifecycle cleanup.
Docker Networks
Networking drivers, custom bridges, host/none behavior, and container communication debugging.
