When I was starting out with docker, everything was really difficult for me to figure out. But don't worry. I'm here 😉
Docker is an AMAZING tool ...

Wish someone could have taught me like this when I was 5 😁 Awesome🚀
thanks a lot!
Docker wasn't there when you were 5 😂
You can map the container's port to your device's port (Which can be anything you want)
so instead of
-p 5000:5000which maps the container's 5000 to your computer's 5000, you can do something like-p 5001:5000which will show the 5000 port in the container, on 5001Damn bro! You are just 16 years old but you explained what Docker really is in a way like you have been learning docker since you were born XD
Very well done. I am really very impressed.
Haha, really!
Wow Really Great Explained. when I first started faced a lot of difficulties to just imagine those basic things.
I know, right! Same with me. I used to try to watch these tutorials which would be lengthy and still ended up confused with the basics
I am learning this concept right now and this explanation was very helpful
thank you for the feedback!
Thank you so much for this tutorial.
Dude!! I got to confess: today I won a battle against prejudice.
When I saw "16yr old" on yet another dev blog, I was about to nope outta here (I've had bad experiences before)
But something made me stay. I couldn't put my finger on it at first, but it turns out that you really have a knack for explaining things (not the same as writing about something). I loved the clean and concise style and even some figures like the one with the bee.
I'm almost twice your age, but today I learned from you.
Keep up the good work, and never stop growing!
it wont run both the container and your original app. but yes, if you manually do it, there will be a collision and only throne that ran first will work (the other will error out)
Awesome explanation, good idea to explain in simple words, so that everybody can understand this.
Your post makes me want to start messing around with Docker. Thank you for your very approachable introduction to Docker.
Nice explanation 😍
Thanks a lot!
Finally someone said it, and in a way that I understand it. There are tutorials for everything but publishing APIs and other "little things" gave me a lot of headaches!
Thank you! Glad I could help
wow! nice 🤗
Thank you!
This is the most precise basic explanation about docker.
Thanks a lot! Glad you liked it
Got me good. Noted.
Awesome explanation, and congrats for this article's hotness 😁 Well deserved 😃
Thank you very much!
Very clear explanation. Thank you!
Really nice explanation!
Very useful and Helpful informative.
Hey this is an awesome article. Great way to put things in an easy-to-understand format.
Love the "explain to a 5 year old" memes
hahah yeah, it's not really for a 5 year old
Super helpful :D Awesome of you to share
Oooh this explanation is amazing!
Thank you. This article has cleared a lot of my confusions related to Docker. I really appreciate it.
Nice explanation 😁
This is awesome
I have no words to describe. this is the best and simple explanation of docker!
i was so confused about containers. thanks alot!!
Awesome post. Do you think Docker is good for local development ? I'm definitely sold that for deployment it is awesome. For local dev, although it saves some environment settings hassles, everything we do now need to be through docker. so far I felt a bit overkill to use docker for local dev environment. appreciate your thoughts!
For local development, yeah, it's not ideal. But for stuff like keeping multiple background processes online, (like running an API on computer when it's on), is an ideal use-case for docker desktop because then you can have multiple stuff running in the background with the minimum memory usage and no hassle of setting it up to run automatically and stuff
If you use vscode, check out devcontainers. They changed my life. I never develop on my host OS and ALWAYS in a devcontainers now.
Yes, I checked it out too. They are really good
Thanks!!!
Great post! well done! 🙌
For anyone interested to learn more, I could suggest this free eBook here:
Free Introduction to Docker eBook
This is an open-source introduction to Docker guide that will help you learn the basics of Docker and how to start using containers for your SysOps, DevOps, and Dev projects. No matter if you are a DevOps/SysOps engineer, developer, or just a Linux enthusiast, you will most likely have to use Docker at some point in your career.
The guide is suitable for anyone working as a developer, system administrator, or a DevOps engineer and wants to learn the basics of Docker.

Thanks to these fantastic companies that made this book possible!
…Good introduction, but I dont agree with the title! A 5-year old wouldnt have learnt anything from this post - probably great for a developer with 1 year experience?
Wish you had written some lines explaining WHY a containerization is needed - what problems existed before!
Overall, this is a great short intro to getting started! Thanks!
Hi there! Thanks for your feedback. The title is just a metaphorical way of saying "in easy terms", and not for a real 5 year old. It's common to see such posts in DEV community
You've made me sad, and I haven't read this yet (I will). Why? Because, for some unknown reason, I was thinking of writing something like this, on Docker, only last week, I was going to call mine "Explain Docker to me like I'm 5 years old", this is not a joke, I will get over it 😭
Well done!
You explained it in such a simple way, while including code and technical details.
I remember some former colleagues talking in 2014 about Docker and saying how it would make life easier for DevOps and Devs.
And the next year I started endtest, to make life easier for testers as well.
Thank you!
Wow, endtest is awesome! definitely will check it out
Nice post. I have increased its visibility already. Shameless promotion just in case anyone want to learn how to create base images using docker scratch or directly from Linux filesystem.
tbhaxor.com/create-docker-base-image/
Awesome Write up and explaination 🔥🚀.
One thing I want to say it's not that important but the file name will be .Dockerfile right
It's written app.py for Dockerfile code snippet/image.
oh yes, my bad. It's supposed to be called Dockerfile. I'll correct the mistake. Thanks for pointing it out!
You explained nicely ☺️
Good explanation
Thanks, simple explanation
Great beginner friendly tutorial man
Good work
Great post 👏👏👏! Cheers
My 6 year old son is now playing docker docker instead of doctor doctor. Thanks to you.
Thank you.
Thank you so much for the lovely and simple explanation! It helped me to conquer my fear of using docker.
