❤awesome, thanks Nana!

Simply superb... Awesome.... Thanks a lot .... NANA.... HAPPY TO SEE THIS

It helped a lot, but there should have volume part as well. Can you add that here?

Amazing course but very annoying with the command line being blocked by KZhead progress bar.

Please don’t stop making videos. Your teaching skills are amazing.

You actually make practical and production level oriented tutorials. This is rare. I like it. Thanks.

Thank you for such a great demo of Warp's features in your video, Nana! Outside of the sponsorship, you did an amazing job with this video. We loved the comparison of what life would be like without Docker Compose & your comparison of Docker Compose vs Kubernetes at the end. Viewers, if you do end up trying out Warp, please let us know if you run into any issues or have feedback 👍

Thank you so much for such amazing feedback on the video! 💙 I definitely enjoyed using the Warp terminal 😊🚀

Available for windows?

im using warp terminal for ubuntu version 22 and after installing it not shown ui page

I've watched some of your tutorials on Docker and now on Docker Compose. I am learning a lot. Thank you.

Names don't need to be creative so long as they're consistent and to-the-point 👍 Your naming convention is great!

Two days ago wanted to find similar video on you channel and here it is 😊 Thank you so much!

You should be declared as de-facto and mandatory tech tutor for almost anything existing on the earth.

Thank you again Nana, You are officially my primary mentor in devops. Your content is so direct and you pack so much in the limited time without us feeling overwhelmed. Keep doing the great work.

The way that you introduce the topics extremely amazing.

I really like your videos and how straightforward you explain things without overwhelming . Thanks Nana

This tutorial is perfect for people who want to start with docker-compose. I use it for a couple of years already. I was a little surprised you used 'docker build' and 'docker push' to build and push the image to the registry. I use docker-compose for that as well. Just supply the image and build arguments in the yaml file and it works with just 'docker-compose build' and 'docker-compose push' as well. This also makes it less complicated.

Thanks for your great and clear tutorial Nana. A video about well-known issues in docker or any DevOps tool will be great.

Everything about the containerized environment, Docker, Kubernetes, Prometheus, minikube, Terraform, Ansible and a lot more I learned only from your videos that successfully landed me a great job as a Senior Software Engineer, There is nothing on your channel that I didn't look. Thank you so much for giving the right path.

Fan of your work Nana ❤. Thanks for educating everyone.

Your videos are uncredible of simplicity and full explanations. All is clear even for neebies! Thx!

Just finished the Docker crash course tutorial, can't wait to finish this as well!!!

Thanks, Nana! After this course my docker-compose knowledge has been more structured 😉

Thank you Nana, Your video was very helpful in helping to understand the concept of docker compose better

Very helpful vidéo ! Thank you so much Nana. i'm a french fifty years old beginner in DevOps. 👍

Thank you Nana for this amazing and high quality video 🙌 Best wishes from Georgia 🇬🇪 მადლობა ❤

@TechWorldwithNana web-application part: I think it is better to use `npm ci` instead of `npm install` to ensure consistency and speed; especially in production. :) (I understand that this is just an example, but I think, it may be worth showing production-oriented orders.) ```Dockerfile FROM node:20-alpine # Set the working directory in the container (If the directory does not exist, Docker will create it.) WORKDIR /home/app # Copy the application files to the working directory in the container COPY ./app . # Install dependencies using npm ci for consistency and speed RUN npm ci # no need for /home/app/server.js [...] ``` Thanks again for your superb content!

Thank You Nana, it was really clear and I learned a lot

Thank you so much ❤ Keep creating amazing content.

Thank you so much, great stuff 😊

version in yaml start is optional. From docs: The top-level version property is defined by the Compose Specification for backward compatibility. It is only informative. Compose doesn't use version to select an exact schema to validate the Compose file, but prefers the most recent schema when it's implemented.

That‘s what I needed. Thanks Nana!

This video came at the right time as I’ve been learning Docker this week 🐳✨

Perfect, hope it will be helpful for you 😊

Such a well-explained video. I think 1Hr max is a good time to not lose your focus and understand topics easily. Thanks for the video and the high quality of it. Keep it up!

Very informative. Thank you!

Great video, going at the right pace, I learned so much. Thank you!

Thanks for this; it is just in time for me to brush up

Thankyou so much.super clear each concept😊🤗

Thank you Nana for this great tutorial.

Hi....Thanks for making this video.This was crisp plus very insightful. Thanks again 💖

Very neat & clean explanation.... Thanks for the video👍

Explanation is great and more helpful to grab more insights' of the platform. Thanks.

A very big Thank You for your kind and helpfull work

explained very easily the best channel for docker and k8s and others

really really cool video nana! thanks a lot and wish you success

Thank you Nana❤️ amazing work!

Thanks so much! :)

Wow you released this video right at the time I ha finished your docker crash course

Hi Nana I've started my DevOps course and I've been following your roadmap....Thank you

That's great! 💪 Thank you for sharing :)

everything is well explain and easy to understand thx

Insightful content, as usual. Thanks once again...

Just love you. You really know how to teach.❤❤❤❤

Thanks, both docker and docker-compose are nice refreshers after not touching this cool tools for some years.

Nice tutorial, thank you 🙂

Great course!! You are excelent!

Nana thanks for everything and i love how you teaching. I would like to suggest to you, since you use Warp, to configure it to display the terminal input lines at the top. I say this because, in my case, as I watch with subtitles sometimes, the lines get mixed up

Well done, thank you very much!

I just dockerized my project for the first time. Yeahh 🎉 to me

Awesome! That was tremendously helpful. Thanks

First, thank you very much for sharing all your knowledge, I have learnt A LOT today. Second, looks like docker componse has been migrated from python (v 1.0) to GO (v 2.0) so now is part of the docker command itself, without the "-". Just in case someone is trying to install something "new" while watching this video (like me :D).

I'm only 16 minutes into your tutorial, but I want to pause to let you know that I really appreciate your clear communication. It's so refreshing. Thank you. I'll check back later.

Comment for the algorithm gods, your K8S and Helm videos helped me a lot!

Happy to hear and thanks for your support 😊💙

Much awaited video.. 😊 thanks

Nana is the best. There are some other good teachers too but she is the best. Nana I love you, thank you for all the hard work you put in !

Thank you so much for great video and valuable information, we are waiting for some videos related Docker file, Docker stack, and finally waiting for Azure devops course which will be golden gifted

Hi great thanks for your profesionell course

Straight to the point notes.

@TechWorld with Nana Really likes your devops videos. Waiting for your devops tool of month series videos.

Great Job, for me You are simply the best 👍

awesome video and really helps a lot

Thank you for this course, it's perfect ! Except for the namings 😜

Thanks a lot! It's a great video for beginners. Docker hub is our future!

Thank you for this video. I do have a few comments/suggestions: - had to add - container_name: mongo in the mongedb service for it to work, don't know why. - ports: - 27017:27017 exposes mongo to the host, but is not necessary in this example because in the stack the containers can access each others ports anyway. Expose as little as necessary. - There's the .env file for setting the env vars which is read by default if present - now there is "docker compose" which is written in Go as opposed to "docker-compose" (python version if I'm correct)

Docker compose demystified in 1 hour.....great content it's.

Awesome tutorial! Hoping that you will make a video about docker swarm.

Thanks for your suggestion, great idea and we will consider it! 👍

thanks you again!

You are a darling! Keep up the good work. Thumbs up!💚

Just what i need it

🎯 One of the best mentors in the devops direction ☁ 🎓✨

Thank you Nana

I would like to hear from you about podman and kind. It would be great to see your insight on this tech. Thank you so much for your effort.

Great Video Nana! Thank you very much! ❤ Love from Israel.

You're the greatest!

Good work Nana 👍

that video help me a lot

Thanks for share

Thanks mam for giving us this amazing content

My pleasure :)

Thanks

Nana, After watching the Docker crash course video, you became my idol. Could you release a new Kubernetes crash course video in 2024? I really want to learn Kubernetes at this time.

You can watch the existing Kubernetes 1-hour crash course, it's still relevant 👍

Спасибо !

Thanks.

Great crash course. Thank you. Do you ever use Docker Swarm? I can see you did not mention anything about it at the end, and just plugged Kubernetes as expected

amazing video. I did the example in a computer running Win10, VSC, and Git bash. Running from the terminal in Visual Studio Code I had to create environment variable with this command: # ======================================================== # Note: # To create enviroment variables in Linux and Mac run this: # export MY_VARIABLE="my_value" # echo $MY_VARIABLE # To create environment variables in Powershell VSC terminal # $env:MY_VARIABLE="my_value" # echo $env:MY_VARIABLE # ======================================================== Thanks Nana, your videos are super usefull.

Nice video Nana. How about replacing the environment variables with secrets stored in files. Docker documentation is confusing. I will figure it out eventually, but I don’t have a lot of experience and I thought it might make a good video.

I was following your Docker Tutorial for Beginners [FULL COURSE in 3 Hours] and I got some questions:- 1. I'm running this NodeJs app on an AWS EC2 instance. How do I get the Public IP address of my instance in the index.html and server.js file automatically cuz every time I start the instance the IP address gets changed. 2. How do I get the Public IP in the container.

your awesome 💪 💪

Impressive

Very informative video Nana! can you please make video on openshift because after kubernetes now software companies are shifting towards openshift from kubernetes 🙂 Thanks for making!!

Thank you for your feedback and your suggestion! 😊 If we see more people requesting a video about it, will create it 👍

Thx for a very well structured and insightful tutorial - thx. One question though regarding "Use image from private repository". How will docker know which private registry to use when pulling an image if the docker compose file contains multiple images from multiple private repos say ghcr and docker-hub and no logins have been provided?

Mam, thanks a lot teaching us... Please make a tutorial on nginx please.

Thanks for your suggestion, was thinking about creating a video about that topic!

Docker compose its the best and easiest to setup and run

One missing point: use ‘docker compose restart mongo-express’ in order to restart part of the composition

Thanks for this tutorial. So can any anyone suggest me how can I duplicate multiple instances of this application with separate db for each application running on unique port number

you are the best

😊

❤❤

Docker secrets only work with docker swarm and docker stacks. So the compose file has to be “adapted” to v3 docker swarm. And that is a problem when u have a complex docker compose file :( Btw, if I am using mozila sops service inside the compose file: how can I assign the value of the decrypted credentials, so the next Service can use those credentials? Pls
