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. 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....

The course content is very good. There was one exercise in OpenShift that I could not do in the Lab Environment. Luckily I had access to another environment where I could do it.

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.

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

It had good information, but I felt the practical examples weren't very good. A lot of it was "copy this command and watch the magic happen" which is great and all, but I didn't really learn *how* to build a Docker container.

- automatic transcription (english) is sometimes not very helpful because of punctuation errors; when reading this, the question often arises as to what this belongs to now - automatic translation (german) even less helpful, as technical terms have been translated: (Docker) Image -> Bild, ... - sequence of facts; partly unstructured (sometimes here a fact about A, then a fact about B and then again about A) - sometimes too technical; what developer needs that? - errors in transcription: - qubectal or cubectal instead of Kubectl - "It is better to define the desired state in a shared configuration file than when you deploy. Kubernetes automatically determines the necessary operations." instead of "It is better to define the desired state in a shared configuration file. Than when you deploy Kubernetes automatically determines the necessary operations." - "Kubectl get commands allow you to listen services" instead of "Kubectl get commands allow you to list services" - "and and symbol" instead of "and Ansible" (Modul 4 > Operators) - markings and language are sometimes not synchronized (Modul 3 > ConfigMaps > ~4:00) - problems with the lab - the output in the terminal is sometimes mixed up (i saw this on screenshots in the peer-review, too) - Modul 3 > Lab: Practice Lab: Autoscaling and Secrets Management > Exercise 2: Implement Vertical Pod Autoscaler (VPA): at the end it says: "You can stop the Kubernetes proxy and load generation commands on the other two terminals by pressing CTRL + C before continuing further", but no proxy was started before - i misses a handout with the pics in the video and some helpful text; as i said before, transcriptions was not very helpful there were sometimes errors in the *.yaml-examples shown - Modul 3 > Autoscaling apiVersion: autoscaling/v1 kind: HorizontalPodAutoscaler metadata: name: hello-kubernetes namespace: default spec: maxReplicas: 5 minReplicas: 2 scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: hello-kubernetes targetCPUUtilizationPercentage: 10 instead of apiVersion: autoscaling/v1 kind: HorizontalPodAutoscaler metadata: name: hello-kubernetes namespace: default spec: maxReplicas: 5 minReplicas: 2 scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: hello-kubernetes targetCPUUtilizationPercentage: 10 - Modul 3 > Rolling Updates > ~0:45 livenessProbe: httpGet: path: / port: 9080 initialDelaySeconds: 300 periodSeconds: 15 readinessProbe: httpGet: path: / port: 9080 initialDelaySeconds: 45 periodSeconds: 5 instead of livenessProbe: httpGet: path: / port: 9080 initialDelaySeconds: 300 periodSeconds: 15 readinessProbe: httpGet: path: / port: 9080 initialDelaySeconds: 45 periodSeconds: 5

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.

If you are coming to learn about docker & kubernetes, there are sure better resources than this.

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