Kubernetes Day 13 – Mastering Manual scheduling Taint & toleration

Kubernetes Pod Scheduling: Node Affinity & Tolerations**
#Key Topics Covered**
✅ **Recap of Day 12**: Environment variables (plain keys, ConfigMaps, Secrets)
✅ **Manual Scheduling**: Forcing pods onto specific node pools
✅ **Node Selectors**: Label-based scheduling (equality-based)
✅ **Node Affinity**: Advanced scheduling with set-based rules
✅ **Affinity Types**: Required vs. preferred scheduling
✅ **Execution Policies**: Ignored vs. required during execution
✅ **Live Demos**: Configuring node labels, pod scheduling rules

Detailed Sections**

#1. Introduction & Recap**
➥ **0:00** – Day 13 agenda: Optimizing pod scheduling
➥ **0:07** – Recap of Day 12 (environment variables, Secrets, Azure Key Vault integration)

#2. Manual Scheduling**
➥ **3:14** – Creating node pools (`small-pool`, `medium-pool`, `large-pool`)
➥ **8:02** – Default scheduler behavior (filter → score → bind)
#3. Node Selectors (Equality-Based)**
➥ **14:21** – How node selectors work (single key-value pairs)
➥ **17:46** – **Demo**: Labeling nodes and scheduling with `nodeSelector`
#4. Node Affinity (Set-Based)**
➥ **22:31** – Why node affinity? (multi-value support, operators: `In`, `NotIn`, `Exists`)
➥ **26:03** – **Affinity Types**:
- **RequiredDuringSchedulingIgnoredDuringExecution** (strict rules)
- **PreferredDuringSchedulingIgnoredDuringExecution** (flexible rules)
- **RequiredDuringExecution** (evict pods if labels change)

➥ **32:59** – **Demo**: Required vs. preferred affinity
#6. Next Steps**
➥ **40:21** – Preview: Tolerations and taints (Day 14)
