An accessible guide to Docker networking that demystifies how containers talk to each other and the host, compares bridge, host, overlay, macvlan, and custom networks, outlines key docker network commands, and maps patterns to scenarios (dev vs. production, security/isolation), capped with a retail microservices example to show how to build scalable, secure, multi-host systems.
Docker Compose streamlines multi-container app development by defining services, dependencies, configs, ports, volumes, and networks in one YAML file, enabling consistent dev/stage/prod environments, one-command spin-ups, easy scaling and collaboration, so teams focus on code not orchestration—illustrated with a Node.js API, PostgreSQL DB, and Nginx web server.
This guide introduces orchestration with Kubernetes, covering core concepts, components, and a "hello world" example to get started. It explores the basics of orchestration, including deployment, scaling, monitoring, and resource allocation, making it easier to maintain and scale applications.
