This course focuses on the most commonly used Kubernetes features as well as provides practical tutorials and real-life examples of deploying distributed applications, managing networking primitives (load balancers, proxies), setting up persistent data storage, dynamic configuration management, and many other exciting features built into the core of Kubernetes.

Unique content - real-life use cases, modern infrastructure, CI/CD/GitOps principles shown in practice.

Certificate of attendance - you will get a shareable online certificate.

Exam after the course - you may pass an optional 1-hour exam and get your score printed on the certificate.

Workshop happens online - join from the convenience of your office or home
