Docker Made Sense When I Stopped Treating It Like Magic

Short summary

A developer explains how Docker clicked once they understood it's just Linux processes with isolation layered on top — not a separate VM. The post covers essential commands (build, run, ps, logs, exec, prune) and argues for starting with a single container before tackling multi-container setups. The conceptual bridge to Kubernetes is natural since pods are just containers scheduled on Linux nodes.

• •Docker containers are isolated Linux processes, not mini VMs
• •Core commands: build, run, ps, logs, exec, prune — start small
• •Kubernetes concepts map directly onto Docker and Linux fundamentals
