VirtualBox seems to be suffering major bit rot. Perhaps the platform-specific setup guidance could be categorized and students directed to jump to the relevant section for their platform.

Great tutorial. Did it a while ago. Taught me a lot about DevOps & about Docker. I since created my own deployment workflow, but this tutorial was my starting point.

good enough to kickstart in docker, I was a bit bored diving in details with ruby or python, but in general its OK
I would call the course - Docker for developers interested in DevOps

Useful overall, but probably should be re-recorded, as many times the flow is interrupted with comments / amemndments made later. Also, Docker is rather one of several topics than the main topic, as the course title would suggest. Yet, like I said, it's useful overall.

Great course. There were several difficulties happened along the way, most of experienced linux users or web app developers should get through easily but I doubt that the beginners might take longer which they should try. Still a good course though.

Actually, this course shifted from writing docker files to how to deploy at staging & production. Also Nick had a pre compiled deploy script with which he does all the staging & production magic. I expected that at the end of the course I would be able to write a Dockerfile from scratch but I am not able to write one from scratch instead i spent my most of the time in setting up the system for being in sync with nick tutorials. Dont recommend to those who are just wishing to learn docker. I recommend them to rather use docker docs which i found out later as the best resource. But yeah if someone wants to get to the very core of deployment & production then this is the best resource ever which walks you through the entire steps with broad details.
This is my honest review & i am not here to impress someone.
Thank You! Best of Luck!

final rev 2.0:

# TLDR; this is an Awesome Course, totally worth it, Nick is great instructor and I will be refering back to this course content again as relevant to what I'm trying to do in real life.

This review is for "Docker for DevOps" by Nick Janetakis, as presented on udemy.com

Nick is a native American-English speaker with a clear voice. He has the right mix of clarity + mild humor so you dont fall asleep. This is very important to me.


Chapter 5+6 contains the Dockerfile + docker-compose.yaml - the true meat-n-potatoes of this course. That is what I paid for and what value I hoped to receive. Nick is apologetic at the length of these two sections, but to me that's what I wanted to see.

A significant chunk of this course was recorded in 2015, with overlay audio track commentary by Nick in the year 2020, and pop-up blue speech-bubbles to issue corrections and updates. Things from 2015 which are annoying and you didn't think you were paying for when you bought this course:
- virtualbox ver 5.x
- detailed setup of debian linux + Digital Ocean droplets
- detailed setup of sudo and ssh
- whats different if you're using MacOS, Windows 7, Hyper-V, Docker Desktop or Windows WSL on Windows 10, or the real Docker on Linux (as God intended).

When I was 2-hours into the course, I resented the filler-content as either too basic or not relevant.
When I was 4-hours into the course, now I was excited because I learned things, and learned how to stitch them together into a usable-coherent whole.
When I was 5-hours into the course, I became sad because I knew the course was winding down.
I guess the only cure is to take more Nick J courses!

I knew enough "nginx" previously but to see Nick put it all together to containerize 2 webapps and use git and ssh and ssl certs and that makes me say "oh wow, this really is DevOps".

However in aggregate, Nick will give very useful commentary or setup or comparison of other tools like vagrant, quick blips on Elastic, Logstash, Kibana, Swarm, kubernetes, et al. This is what you are paying for, for a guy with 20+ years of experience to tell you What's Up, rather than some fool who stumbled his way thru a CompTIA Cert 6 months ago, but ultimately has no real-world experience.

My wishlist is you would re-record the entire course using virtualbox 6.0 and the best linux, fedora or rhel. I love virtualbox and have been using it since the days of UnderRoos. virtualbox on a local machine you own will save you $1,200/year compared to doing it all on AWS and paying by the minute for every S3 request + hour of uptime on an EC2 instance.

Maybe scale back the Digital Ocean section in favor of a section on AWS, if you decide to produce a 2021 revision of the course.

udemy.com Technical Issues during the course delivery:
Firstly,
whatever CDN tricks udemy is using, they didn't mesh well with Firefox 76. In almost every chapter where there is downloadable content in form of a .pdf attachment it would cause the bottom video player controls to disappear, and my page lesson would abruptly skip to the next lecture. That was no bueno and I would have to hit Back or F5 to reload the page.

Secondly,
the .pdf or .zip file course attachments either had the same filename 'original.zip' for EVERY chapter, or they would have unintelligible ${UUID}.pdf file names. You have to rename every file to keep them sorted.

Thirdly,
the audio level is all UP and DOWN from your inserted comments & revisions from Future Nick. A little auto-gain / auto-level to keep it all at a consistent "7".

very good course! the instructor is also highly skilled and knowledgeable in the subject.
my main criticism of the course is that the fonts are too small which makes it a pain to follow along. Selecting 1080p does not help much.
