In this lesson
know the problems Kubernetes solves and when it is worth its cost.
Planned topics
- It schedules containers across machines, restarts failures, scales, and rolls out updates.
- You describe the desired state in YAML; the system works to match it.
- Cost: complexity and operational skill; a managed cluster reduces it.
- Not every system needs it; a handful of services may run well on simpler platforms.
