DevOps courses - Kubernetes на практие

Kubernetes

Practical kubernetes

The course is suitable not only for DevOps engineers, but also for developers, dealing with k8s. It includes all the important practical knowledge, necessary for work. The course is based on an approach “from practice to theory” - you won’t be bored!

Start for free

First 4 tasks in the course are free

Let's launch the cluster, connect to it, find out what connection methods there are and choose the most convenient one

Next, run a test load and figure out exactly how containers are launched in a Pod

After that, you will learn how to create manifests describing Kubernetes resources, and also explore all the most popular resources that are required in daily work

Let's look at how the load is distributed across the k8s cluster, what types of nodes exist, and how we can limit the consumption of individual applications to ensure reliable operation of the entire cluster

Dive into the network part: services, port-forwarding, ingress. Let's launch the load balancer and cert-manager to issue a real SSL certificate.

Notice the difference between stateful/stateless services. Let's connect volumes to store application data and their configuration (configmap/secrets)

Learn how to run scheduled tasks via cronjobs, as well as select the node on which to run the application.

Learn more about scaling both pods and the nodes themselves in order to dynamically change resources and withstand the load

And of course, we will study how it is possible to strengthen the security of applications and the entire cluster through service accounts and Role Based Access Control

What do I get after completing the course?

Ability to run applications on a Kubernetes cluster
Understanding limitations and how to overcome them
Ability to operate all basic resources in k8s
Ability to solve a full range of problems to ensure the availability of applications from the Internet
Ability to scale applications depending on load
Understanding how statefull/stateless applications work

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)

How it works

/01

You receive detailed instructions and theory for completing each task and a ready-made test stand

/02

After completing the task, your result is automatically checked

/03

For each course assignment, you can ask a question to the author and receive an answer. It is important to us that everything is clear to you

Reviews

I really liked the course (Kubernetes)

Everything is well presented and understandable. If anyone asks for a Kuber tutorial, I will recommend your course first of all. Thank you!

(Kubernetes)

The course for a person who has never dealt with K8s, gave initial skills, everything was described very pleasantly and well.

Good course with practical tasks(Kubernetes)

This is a really valuable course on the most important and relevant sections of Kubernetes. Now, after completion, I use it as a reference in my work.

Mike, reg date: 12.08.23

The workshop is clearly underrated(Kubernetes)

K8s courses cost several times more, but they still wouldn’t give such a level of immersion in practice as here. Plus real savings on cloud resources. I always received a quick response to any questions I had.

Yohan, reg date: 28.08.23

Interesting format(Kubernetes)

I think that the course is ideal for those who value time and do not like to watch a lot of videos. Literally from the first assignment I was immersed in practice, and it’s really interesting!
