✅ Chapter 05: Namespaces & Resource Management – Structured Learning Index

🔗 Prerequisite: Chapter 04 (Services, Probes) — ✅ you’ve mastered it!

Phase 1: Namespace Basics & Quotas

Isolate workloads and set hard limits on resource usage.

1. namespace-pod-quota.yml

   → Limit number of Pods in a namespace.

2. namespace-resourcequota.yml

   → Limit total CPU/memory in a namespace.

Phase 2: Default Resource Constraints (LimitRanges)

Set default requests/limits for Pods that don’t define them.

1. limit-ranges.yaml

   → Basic default requests/limits for containers.

2. namespace-cpu-limitrange.yaml

   → CPU-specific defaults/min/max.

3. namespace-memory-limitrange.yml

   → Memory-specific defaults/min/max.

4. limit-ranges-default-min-max.yaml

   → Comprehensive min/default/max for CPU + memory.

🔗 Recommended Learning Flow

1 → 2 → 3 → 4 → 5 → 6

✅ Why this order?

• Start with hard quotas (what you can use)
• Then default constraints (how you use it)
• End with comprehensive policies
