Scheduling And Resilience

Scheduling is not only placement. It is the cluster making tradeoffs under constraints.

Topics

• kube-scheduler - The scheduler picks a node for Pods that do not already have one. It filters impossible nodes and scores the rest.
• Node Assignment - Node assignment is how workloads express where they can or should run.
• Taints, Tolerations And Affinity - Taints repel Pods. Tolerations let Pods accept that repulsion. Affinity attracts or separates by labels.
• Priority, Preemption And Eviction - When capacity is scarce, Kubernetes needs rules for who gets scheduled and who gets pushed out.
• Disruptions And Maintenance - A disruption budget tells Kubernetes how much voluntary disruption an app can tolerate.

Editorial Notes

• Keep the official docs as the citation layer.
• Keep this lab opinionated around homelab operations: verification, failure modes, and practical boundaries.
• Avoid copying upstream prose; cite it, then explain the operating model in our own language.
