Kubernetes Scheduler (en)
The course will address the concepts of Kubernetes workload assignment, and will then continue with theoretical explanations and practical demonstrations that will help the student to control the assignment of resources and the destination of the Pods.
The course includes exercises in a laboratory environment where the student will be able to apply what is being addressed by consolidating the concepts. The course will lead the developer or system administrator to have more decision-making power in assigning certain resources to certain nodes.
As a prerequisite, it requires having completed the DSK201 or DSK202 courses
COD: DSK305
Categories: Kubernetes
