Day 29/40 Kubernetes Volume Simplified | Persistent Volume, Persistent Volume Claim & Storage Class

Welcome to the Certified Kubernetes Administrator (CKA) series! This is Day 29 of 40.
In this video, we will delve deeply into Kubernetes Volumes and explore the concept of Persistent Volumes, Persistent Volume Claims, and Storage Class in depth.

👨🏼‍💻 #40daysofKubernetes Challenge:

📖 Course Schedule:
I'll release 3-4 videos per week and host live Q&A sessions on weekends to answer your questions and guide you through the CKA certification process.

🕵🏻‍♂️ Who Should Watch:
This CKA course is designed for beginners, college students, and working professionals who want to learn Kubernetes from scratch, prepare for the CKA certification exam, or enhance their knowledge. It was designed based on the latest curriculum for the CKA exam in May 2024 and uses 1.30.2 as the Kubernetes version.

Let's start your Kubernetes journey together!

First Comment, Thanks for the detailed explanation on K8s Volumes concepts. Thank you Piyush

Thanks for this well explained video on PV, PVC, SC.👍

To answer your question : How did we manage to schedule a pod on the control-plane node?

In K8s control plane nodes (master) are tainted to prevent pods from being scheduled on them. In this case, we specified nodeName explicitly in pod yaml, saying that place a pod on to master node overriding the normal default scheduling process, because this gives pod explicit ability to place on the control plane node, regardless of the taints in place.

But, this is not ideal in case of production environment real time, we use a combination of taints and tolerations and nodeSelectors or nodeAffinity to allow a pod to be scheduled on a specific node.


1. Taints and Tolerations: Taints applied at node level, Tolerations at pod level - This gives node ability to allow which pods to be scheduled on them.(Node centric approach)
2. Nodename, Nodeselctor and label: This give pod ability to decide on which node it has to go.(Pod centric approach)

How we can schedule workloads on control-plane node? As you mentioned in the series, we can use taint for nodes and toleration for workloads to permit them schedule on control-plane or specific nodes.
