50 Kubernetes Concepts Every Devops Engineer Should Know Free Pdf ((full)) May 2026

While there isn't a single official "50 Concepts" free PDF from the Kubernetes project itself, the book 50 Kubernetes Concepts Every DevOps Engineer Should Know

PersistentVolume (PV):

A piece of storage in the cluster provisioned by an administrator. While there isn't a single official "50 Concepts"

RBAC (Role-Based Access Control):

Regulates access to resources based on the roles of individual users. providing a way to automate tasks.

To make this your daily desk reference, we have compiled all 50 concepts, architecture diagrams, and CLI cheat sheets into a single resource. Download your free PDF copy here.

29. CNI (Container Network Interface)

: Lets Pods expose their own metadata (like Pod name/IP) to containers. Roadmap.sh Storage Management Handling persistent data in a containerized world. : Directory accessible to containers in a Pod. PersistentVolume (PV) : Cluster-wide storage resource provisioned by an admin. PersistentVolumeClaim (PVC) : A user's request for storage. StorageClass we have compiled all 50 concepts

Part 3: Networking (The Hardest Part)

  1. Persistent Volumes: Persistent Volumes (PVs) provide persistent storage for Pods.
  2. StatefulSets: StatefulSets manage stateful applications, providing a stable network identity and persistent storage.
  3. Volume Mounts: Volume Mounts provide a way to mount volumes into Pods.
  4. Storage Classes: Storage Classes provide a way to provision storage resources dynamically.
  5. Dynamic Volume Provisioning: Dynamic Volume Provisioning allows for automatic provisioning of storage resources.
  6. Persistent Volume Claims: Persistent Volume Claims (PVCs) request storage resources from a Storage Class.
  7. StatefulSet Scaling: StatefulSets can be scaled, and their Pods will maintain their network identity and storage.
  8. Rolling Updates: Rolling updates allow for updating StatefulSets with minimal downtime.
  9. Pod Management Policies: Pod Management Policies control the behavior of StatefulSets during scaling and updates.
  10. CronJobs: CronJobs run Jobs on a schedule, providing a way to automate tasks.
