Kubernetes Advanced

Kubernetes has evolved over the years into a comprehensive solution for container orchestration with plenty of integration practices. However, it is still not a platform that is ready for direct user use and requires knowledge of the whole system.

The training focuses on the advanced management and operation of the Kubernetes cluster. We expect common knowledge of Kubernetes and focus on related topics such as integration with CI / CD, storage, resource allocation. Last but not least, cluster security is emphasized.


  • Application developers
  • Cloud Platform Engineer
  • IT systems designers


  • Fundamental course Kubernetes
  • Basic Kubernetes terminology and architecture (pod, service, deployment, ...)
  • Using terminal to run commands

Course goals:

This traning is intended to be a Kubernetes deep dive and some prior Kubernetes experience is required. We are focusing on advanced topics like real workload management, LCM and cluster security. Most of the topics are demonstrated on live enviroment and every attendee will get and opportunity to test everyting on dedicated cluster.

It's planned that some topics will be skipped according to attendee preferences and others will be presented in detail.

Tomáš Kukrál - instructor of the course

Tomas develops the edge cloud platform based on Kubernetes at Volterra. In the past, he worked for Mirantis and was in charge of designing Kubernetes clusters and delivering them to their customers. In his free time he is involved in parachuting and cycling.
