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....

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.

Overall, the course itself was nice. The course videos and labs helped solidify my experience with Docker, Kubernetes and OpenShift. However, the one thing that really killed this course was the final project. Other courses I've taken so far will tell you where to take screenshots, but this one did not. If that wasn't bad enough, you will need to delete something as instructed in the project guide and need to take screenshots of the state before the delete. I see in the discussion forums that a lot of people had to reset their projects due to not knowing about what screenshots to take until the very end. There are little to no threads discussing how to reset the final project.

I like that there are a some practical parts in this course, but I don't find helpful how they are represented (If I want to do everything on my own, I can't do it) . They already give you the code, with simple explanations. The course should have a homework part where you can create a dockerfile and .yml for yourself. Learn when to use each type of .yml . Also, Kubernetes has a dashboard, so it could be useful to learn how to use it too.

Good intentions to provide a controlled, simulated lab environment when the course matter consists of large systems. There was however quite some trouble with that lab environment. (Quick response and adjustments from the course responsibles though.) The theory was mostly an enumeration of facts about Docker, Kubernetes and OpenShift. I missed descriptions of problems and system design reasoning.

Week 2 was extremely difficult because every word I hear in the video is a new term and the tutorial didnt take time for the important ones to seep in. Hope that can be improved, perhaps by splitting the week's content more evenly. The remaining weeks and the labs were very nice and helpful.

the pear graded system (a student graded another student's work) is somehow not good. if one student didn't realize the grading standard well, or not understand the studying content so well, he would likely give wrong scores/comments to other's work.

Too much dense, terminology introduced without a real context, in particular in the module dedicated to OpenShift and Istio. Good the opportunity to try all the softwares directly in the browser.

I feel that the information provided was too breif and not explained in enough detail to adquately prepare the student to complete the test and assignments required for this course.

The topic is interesting and labs are good, but machine-recorded voice is of much lower value than a human trainer explaining concepts. I do prefer AWS tutors and training.

In this course you will hear tons of concepts in just a few minutes. It's up to you to search and understand those, if you want to be able to use them.

the slides are so monotone and full of text, and read by an AI voice, you hardly grasp the whole picture.

Week 1 and Week 2 too long

Was a lot of rote-stating definition with little context as to what these different functionalities are used for with examples. Instead they only provide context for what they do within Docker and Kubernetes. This is quite confusing as this course is supposedly aimed at people with no experience of either application. Also the final project is a joke and is pretty much a step by step follow along guide with little room for actual learning or attempting to make the student think at all. Half the steps are incomplete in their description causing you to "click to view hint" to see what they are even asking, which just spits out the example code that you can just copy and paste to get the right answer. For example, "autoscale the deployment" and the only way to find out how much the assignment creator wants you to autoscale the deployment by is to view the hint. How that is supposed to test anything, I don't know.

Doesn't really seem to add anything you couldn't get from reading documentation. https://docs.docker.com/get-started/docker-overview/ https://kubernetes.io/docs/tutorials/kubernetes-basics/ https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/getting_started/openshift-overview
