It's an excellent tutorial, I especially like that you use a nice little demo web app. That makes it more interesting and realistic than just abstract or random examples. I'm curious, what software did you use for the animations and video editing?

Nana !!! Simply I can say fantastic work done by you....

[@theoverlander4579]

VERY IMPORTANT FOR NEW WATCHERS: doing this with the latest version of mongo/mongo-express will result in an error during first setup. I found a fix for it though. The video is 4 years old, so I went and got 4 year old versions of mongo/mongo-express off of dockerhub, and it works just like the video intends. commands: docker pull mongo-express:0.49 docker pull mongo:4.2.1 hopefully you find this if you're stuck.

[@grimquokka9843]

why can't we use the latest ones dude?

[@zedpoutine]

And update commands to specify version : docker run -p 27017:27017 -d -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --name mongodb --net mongo-network mongo:4.2.1 docker run -d -p 8081:8081 -e ME_CONFIG_MONGODB_ADMINUSERNAME=admin -e ME_CONFIG_MONGODB_ADMINPASSWORD=password --net mongo-network --name mongo-express -e ME_CONFIG_MONGODB_SERVER=mongodb mongo-express:0.49

12mins into the tutorial and I feel that Docker is a small os dedicated and configured just for one service. am I right?

[@fareedezzedeen8017]

@YTG No, but there were VMs, hypervisors, and OS images that can run on different OS, Similar concepts But before 30 years as I remember, we used to have full-length cards that are a full-fledged PC, and we can install them in another PC. In mainframes, IBM started providing multiple machine threads on the same hardware technology.

I ran the code on the gitlab which is provided in the description under the links section. The app still connects to the mongodb. We do not need the mongo-express. The js file is altered from the one in the video so that it does not require a user-account database and mongo-express. Currently, mongo-express can not connect to the mongo database by using the commands in the video, because of version differences. I made it work with mongo-express:1.0.0-alpha.4 . It was published in 2022. Just alter the command in "Developing with Containers Part" 'mongo-express' with 'mongo-express:1.0.0-alpha.4' at the end of the command . It works just like in the video.

I have been trying to learn docker from a long time and have seen various videos. But I can confidently say that this is the best tutorial on Docker that I have seen so far. For the first time, I am feeling confident about my docker knowledge. The explanation was up to the mark with all the required details for a newbie like me on docker. Can't thank you enough Nana for all the hard work and time that you have spent on this video.

[@wkjagt]

Such a great presentation of Docker. I've read multiple guides, watched multiple other videos, but none were this clear. What I really like about how you structure your knowledge is that you start with the foundational functionalities, and then gradually build on top of that by showing an easier way to do it. For example: instead of just showing how to use Docker Compose, you start by showing all the commands manually. So when you show Docker Compose, I end up understanding why it exists, what it replaces, and what it does exactly. For example, I would never have known about what happens when it creates the network, and why it does it if I hadn't seen you go through all the steps manually first. Great stuff. Thanks for doing this.

[@manognajoshik8465]

Exactly my thought. But I wouldn't be able to put it effectively in words like you did!! She doesn't state why something is needed but gets us to understand it by showing what was missing without it.

[@carolinecares9]

I am a complete novice where tech is concerned. I decided to learn some of these aspects amongst others, and discovered you, Nana, during my exploration here on YT. Having a background in training I will share that you have a remarkable way of translating things that can go into jargon, feel so simple. This is your gift! I am currently on this 3-hour course with you and everyone here, and want to acknowledge and thank you for choosing to create this - not so easy but completely understandable- program in such a powerful way. This also goes to show how your own mind works- you have the ability to dumb it down to an understandable degree. thank YOU very much Nana ! Kudos

[@jaykeer8662]

An absolute gem! A week ago I knew nothing about Docker and was kindof intimidated by the sheer number of resources available not sure which one I should refer but this hit the mark.

Overall a perfect course to recommend to anyone. 10/10 keep growing !!!

Small addon: Run commands are executed only at the image build step. All changes introduced by the Run command creates a new layer and will be committed to the container image. CMD command is auto executed when the image is launched and can be overridden.
