Certified Kubernetes Administrator (CKA)
Running Kubernetes in production requires more than basic knowledge. The CKA certification validates hands-on administrative skills – from cluster setup to security hardening and incident diagnosis in operational environments.
Key topics
- Understanding Kubernetes architecture and building clusters
- Planning, scaling, and managing workloads efficiently
- Configuring networks and securing service communication
- Managing storage solutions, volumes, and persistent data
- Applying monitoring, troubleshooting, and security concepts
Prerequisite
Experience with Linux, networking, and container environments will make it significantly easier to get started.
Target group
Those responsible for Kubernetes clusters in cloud or infrastructure projects – from administration, DevOps, and platform operations.
The CKA certification demonstrates that professionals can independently administer Kubernetes in complex environments – a sought-after qualification in modern cloud projects.
