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.

 

Audience

  • Application developers
  • Cloud Platform Engineer
  • IT systems designers

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.

Lecturer Tomáš Kukrál acts as (and certainly is) number one in the field. The training was very proactive with elements of both intentional and unintentional accidents where one really learns. I really recommend it.

Although the training was virtual, it was completely without mistakes. Perfectly prepared lab environment, reasonable distribution of time for interpretation and labs. Tomas is an excellent trainer and especially an expert in the technology. The content of the training met my expectations. I recommend to anyone who wants to deal with Kubernetes.
