About the Course

Take the next step in your software engineering career by getting skilled in container tools and technologies! The average salary for jobs that require container skills is $137,000 in the US according to salary.com, making Devops professionals and developers with these skills highly in demand. More than 70 percent of Fortune 100 companies are running containerized applications. But why? Using containerization, organizations can move applications quickly and seamlessly among desktop, on-premises, and cloud platforms. In this beginner course on containers, learn how to build cloud native applications using current containerization tools and technologies such as Docker, container registries, Kubernetes, Red Hat, OpenShift, and Istio. Also learn how to deploy and scale your applications in any public, private, or hybrid cloud. By taking this course you will familiarize yourself with: - Docker objects, Dockerfile commands, container image naming, Docker networking, storage, and plugins - Kubernetes command line interface (CLI), or “kubectl” to manipulate objects, manage workloads in a Kubernetes cluster, and apply basic kubectl commands - ReplicaSets, autoscaling, rolling updates, ConfigMaps, Secrets, and service bindings - The similarities and differences between OpenShift and Kubernetes Each week, you will apply what you learn in hands-on, browser-based labs. By the end of the course, you’ll be able to build a container image, then deploy and scale your container on the cloud using OpenShift. The skills taught in this course are essential to anyone in the fields of software development, back-end & full-stack development, cloud architects, cloud system engineers, devops practitioners, site reliability engineers (SRE), cloud networking specialists and many other roles....

A good introduction to Docker, Kubernetes and OpenShift. I really enjoyed the hand-on labs. They're an efficient way to understand how abstract concepts can be applied.

Very nice course, which uses a simple hand-on approach with just the right amount of theory to get yourself started with Containers and Kubernetes. Highly recommended!

It was a good beginner's course, for my next level I would like a little bit more hands-on.

Had high hopes for this course, but it is NOT worth it. Along with a few other issues the lab environment is unbearable.

The information in the instructional portion is great and easy to follow along to, but I've run into multiple issues with the lab environment including:

- Running into connection errors,

-Not given proper guidance on replacement criteria (for example it will say something along the lines of "input <$YOUR_ACCOUNTNAME>" in which case you don't know if you're supposed to use <ACCOUNT_NAME>, ACCOUNT_NAME, or $ACCOUNT_NAME and have to play around with multiple inputs before getting the right one

- Most frustrating was not being able to troubleshoot. Some connection issues can be resolved by logging out and clearing cache according to the forums, however I was physically unable to logout as the lab environment stalled for 15 minutes before I gave up.

Additionally, you will NOT receive feedback on incorrect quiz answers so you'll be left not knowing why you were wrong and have to research answers on your own.

After completing a few weeks of assignments I will not be finishing the course as it is not proving to be worth it.

The AI-generated videos were pretty terrible for this course. Since this course was one of the first where I actually didn't know any of the material going into the course, I found it much more difficult to follow along with the videos than some of the previous courses. The labs for Week 2 and Week 3 didn't work correctly for me, even though I was following the instructions exactly. The labs for this course, in general, felt very "copy-paste", and I don't think there were enough opportunities for practicing skills used in the labs (i.e. repetition). I felt like I learned practically nothing from this course.

Course is well-structured, but:

- It is very basic. We are only touching some k8s concepts

- Video are way too abstract. No-one is showing you how this theory could be applied, just some general concept that you can't get idea of. Also it is just a written text, so robot is reading it.

- Hand-ons are very basic too. Smth like 'we provide all of the configuration for you, just run kubectl apply'

- Final assessment is very basic also

The content has a few ordering issues and some of it wasn't all that great. Not a lot of depth is covered, and, due to that lack of depth, some of the assignments and content choices do not feel consistent. In spite of those issues, I would probably have rated this 4 stars if not for the soulless, robotic lecture voice. If every class in the world was taught in that voice, we might all freely choose ignorance.

The information provided only gives a superficial overview of the topics and cannot fully help in understanding them. Additionally, a lack of real-world problems that can be solved using Docker, Kubernetes, and OpenShift is present.

Dense, boring and of little utility. Just a readout of terms without proper explanations.

One of the worst courses I ever had. 1) Information is given poorly 2) The videos do not have any sense because most of them are just voiced text with pictures without describing things in an understandable way 3) The assignments it is just copy/paste 4) The platforms are bugged 4) Many people complain about the quality of the materials, but I haven't even seen detailed answers and plans or even promises to change it. In summary i think it is a shame for IBM to have this course.

Minimal efforts are put while creating the whole course. All I heard was a robotic voice going over all concepts recklessly. I don't think this is a very digestible content and I still don't feel very confident applying the concepts I learned. Disappointed by IBM..

This is not a course. It's just a demo to show that Docker is good! You will learn nothing from a narrator who I don't know if they are human or AI. Just know that without any emotion, she just reads a script, and it's not an educational course! Shame on IBM.

It's like textbook, only gives concepts with very few examples. Explains the 'what it does' not 'how it does it'. Worst of all, it is very lacking in labs, should provide at least 2 practice examples for each week topic.

Absolute worst. The machine voice is annoying already, and there is no explanation by a human instructor nor even a glimpse of effort to make the topic understandable. Learned nothing. Absolute garbage.

Too much information on Kubernetes. It should be taken slowly, step by step. Useless tutorial as it goes to advanced level. I have to study too much from elsewhere.

This a horrible course! The speaker is a pain to listen to, the content is read off a text book much too fast...

Rafano's courses are a positive example!

This is a copy paste from a corporate training.

There was not even a real professor but it was just an AI voice over of slides.

I would say the course was a good, somewhat technical introduction to containers, kubernetes, docker and open shift. I would also say that the final assignment can be difficult to complete as you are to submit screenshots of version 1 of the app you deploy, but you are also tasked with replacing that version during the final lab assignment. How can you capture a screenshot of something that doesn't exist? I had read what was needed for the assignment, so I was able to take screenshots as I went through the assignment.

The instructor really knows their stuff, explaining complex ideas in a way that's easy to understand and interesting. It's a well-organized journey for beginners, giving you a solid base if you're getting into container orchestration. I highly recommend it for its clear explanations, in-depth content, and hands-on learning style
