Docker - Containers, Images, Compose, Kubernetes, and more! (Udemy.com)

Nice introduction to Docker. I learned a lot, and I feel more comfortable applying what I learned to a personal project. The author does his best to explain complex topics. However, sometimes, I felt a bit overwhelmed, especially in the sections about Docker Swarm and Continuous Delivery, where a lot of things come together. Some visuals, like diagrams of what's happening, might have been helpful. I had to keep a lot of things in mind and concentrate. Some videos need to be updated, but I could still follow along and figure out the missing parts myself. All in all, a helpful course to get started with Docker.

That's awesome! At the beginning, I just wanted to know the basics of Docker and Docker-Compose and didn't want to dive in depth, because it seemed to me very complicated, based on what I found in other resources. But this course, thanks to the instructor, David Joseph Katz, was very understandable, which encouraged me to follow it step-by-step. It's understandable and the language is very clear, even for a non-native speaker like me. I like the explanation and the sentences being chosen. I owe you David a Thank you. Iyad

Good Course, giving an introductory insight into Docker. I especially liked Sections 1-4 and 7. Sections 5 and 6 are a bit fast and while I theoretically understood everything, executing the code did not work for me. A bit more troubleshooting information (especially for students following from non-Linux operating systems) would have been nice. Section 8 (Docker Cloud) was, as announced largely outside of the scope of this course - instead of having a lot of hands-on here, I would have preferred to have a bit more theory to improve understanding instead of doing hands-on exercises which will be of limited usability on their own later on. Overall, this course build a good understanding of Docker and I would recommend it

The course provides a very good overview of how the Docker Daemon and Docker Containers relate to each other and the underlying Host (O/S) Kernel. The only slight issue is that the process for installing Docker on Windows 10 Pro and enabling virtualization on my machine was different to that presented, but that is a perennial problem with software training packages and will present no problem for any reasonably competent software engineer. Likewise, in using Windows Powershell on Windows 10, it was necessary to convert especially text files to LF-only EOLs, and there were a couple of other slight tweaks, in addition to having to add an SSH key from my laptop to the github account via Personal Settings - SSH and GPG keys. All-in-all, however, the course has exceeded my expectations, so many thanks.

Overall a great course to get novices like me up and running with Docker. David did a great job explaining the concepts from the ground up and complement the theory and code implementation with the perfect balance! The supplemental resources in the form of a GitHub repo for the course, the slide deck and lecture and section summary notes are incredibly helpful to reinforce the knowledge. These extra materials really make it obvious that the instructor put a lot of effort into building this course. I am now quite confident to use docker in my personal projects and feel ready to dive deep into more advanced DevOps topics! Thanks David! Keep up the amazing work. Hope to learn more from you in the coming days.

This course introduces a lot of interesting and useful material about Docker. The examples from the web development world are all new to me as that is not my area of expertise, but they do a good job of illustrating Docker's power for those applications. I was hoping to hear something about using Docker for cross-platform development which is what I had heard about Docker but it's too big a system to cover everything. I think that the course could use some refinement in pedagogy. Maybe a little more repetition when presenting the commands--it was impossible to keep up and too easy to miss a critical step. Then the example doesn't work, and I had to watch the whole episode over to figure out what went wrong. Along those lines it would be very helpful if some beginner mistakes could be anticipated. Just write down what went wrong during the development of the examples, and share those experiences. I loved the course, and recommend it, but it took longer than advertised because of the innumerable gotchas. The text on the screen shots was too small for me--I can't keep my laptop in fullscreen mode and still be able to switch to my work, and some of the web screen shots were too fuzzy to be readable. A little more attention to those teaching details would be nice for students. But I love David's energy and the complex examples, and I learned a lot about Docker, which is the purpose of the course.

in general is a good intro course that covers some topics at a very high level. I have a few remarks though docker swarm could have a bit more information like how changes replicate across nodes/replicas the example for the continuous integration didn't really work out of the box for me. the Q&A section is a bit of a desert with almost no replies (I eventually got all the replies but took a while). Also could you please maybe share your github code for this course? edit: just got a reply and you can find the code for the examples here. that helps a lot https://github.com/15Dkatz/docker-guides

This a great introductory course to Docker and docker applications. The content is clear, with workable examples, and Davied paces the information just right. The sequence of topics is logical, so that one topic naturally builds up to the next. The examples are clear and easy to follow even you have never worked with flask, nginx or posgresql. The configuration of these programs is given, so that you can focus on the important things about docker configuration and administration. The range of topics is wide enough that by the end you will be able to start working with containers and groups of containers right away, and your grasp of the main concepts will be firm enough as to be able to face other, more technical sources of information about docker.

Davids's precise and very carefully worded explanations and instructions provide detail on docker, docker containers, docker images, Dockerfiles, docker-compose files, swarms etc in an easy to comprehend manner, with a series of working examples that provide practical experience. The use of node.js, php, flask etc in the examples gives a brief introduction to these topics. Additionally, David gives an introduction to, with step by step working examples, to AWS EC2, docker cloud and github, and the possibility of Continuous Integration. A very enjoyable and useful course.

-- beginning of the course -- So far good ~ Instructor assumes very little from students. For example he start with the question what is kernel which I did not know what it was before. -- half way through the course -- I tried at least 6 different free or paid docker courses online. As a complete beginner to docker, this course is by far the best. Especially if your background is front-end web developer who wants to understand how docker works, you will be very happy taking this course.
