In this video, we explain Kubernetes NodeSelector from scratch using real handwritten notes, YAML code, and kubectl commands.
You’ll clearly understand:
• What NodeSelector is in Kubernetes
• Why because automatic scheduling is not enough
• How Kubernetes decides which node runs a Pod
• How to label nodes and bind Pods to specific servers
• Why Pods go into Pending state
• Real production pain points and use cases
This explanation is simple enough for freshers and deep enough for experienced engineers, despite of complex Kubernetes scheduling topics.
If you are keen on learning real Kubernetes internals, this is where you should start.
Covered Topics:
✔ Kubernetes Scheduler Basics
✔ Node Labels
✔ NodeSelector YAML
✔ Pod Pending Issue Explained
✔ Real kubectl Commands
✔ Production Use Cases
