Who is this course for?
For devops engineers, developers and other IT specialists, who somehow deal with Kubernetes. Currently the level the adoption of this product is very high among various organizations and understanding the intricacies of its work are often required.
How does automatic job verification work?
Depending on the task, a special algorithm inspects the resources of your Kubernetes cluster and compares your work with the required result
What basic training do I need to complete the assignments?
You will need confident terminal (console) skills and basic knowledge of working with client-server applications
How long is this course for?
The estimated time to complete this course is 20-30 hours. There are no class schedules, you learn at a pace that suits you and always pick up where you left off.
If I haven't found the answer to my question, can you help?
Sure! If something is not clear at any step, then ask. If there is no information at all, ask too. Perhaps we will add a new section.
Can I skip some tasks and go straight to the free one?
Yes you can. However, it should be taken into account that some tasks depend on one or more previous ones. In this case, you need to complete them first. For example, you cannot run something in a cluster if you have not completed the first step (launching the cluster itself)
