Kubernetes Administration with Helm and CKA exam.prep.

Kubernetes is the leading open-source system for automating deployment, scaling and management of containerized applications.

This course introduces participants to the basic concepts and architecture of Kubernetes, its Initial install, setup and access control, Kubernetes Pods and Workloads, Scheduling and node management, Accessing the applications, Persistent storage in Kubernetes, its Logging, Monitoring and Troubleshooting facilities and finally Helm, the Kubernetes Package Manager.

The course doesn’t only prepare delegates for the daily administration of Docker & Kubernetes systems but also for the official Certified Kubernetes Administrator (CKA) exam of the Cloud Native Computing Foundation (CNCF).
