Kubernetes Fundamentals: Docker vs K8s, Runtime, Pods & Deployments
Kubernetes is a container orchestration platform: it schedules containers onto a cluster of machines, keeps the desired number of replicas running, handles networking and service discovery across node
Learning objectives
- Explain precisely what problem Kubernetes solves that Docker (and Docker Compose) alone don't.
- Explain what a Pod actually is, and why Kubernetes' smallest deployable unit is a Pod, not a container.
- Explain what a Deployment adds on top of a bare Pod, and why that matters for real production workloads.
