First time in my life watching something related to Docker. Understood everything. Put it into practice on my own project. Absolutely outstanding tutorial. Best there is by light years!
I am speecheless...I knew nothing about Docker an hour ago and here am I already creating my own images and running them inside containers. What a tutorial!!!!!!!! Thanks a ton Nana. I had to hit that Subscribe button! 🙏🔥
That's amazing, welcome to my channel! :)
I have watched around 5-7 "beginner" tutorials on Docker, but none came even close to the comprehensiveness of this tutorial. This tutorial clarifies thoroughly the fundamentals of Docker at a perfect pace! Forever in your debt! :D
when she explain what VM is compare to docker, and what docker Desktop basically run a Linux VM, everything just make sense now 😀
This is the best crash course I have seen on Docker. In 1 hour I was able to fully understand the basics that I have struggled with for a while. Thanks Nana!
I'm a long time follower of your channel, and love the way you teach. There are a lot of very talented instructors here on KZhead, and I appreciate every one of them. What sets you apart from the rest is that you explain even the little details that everyone else glosses over, for example, " -it means interactive terminal " . That one little detail made learning k8s so much easier! Please keep up the great work!
Hi! I have been working towards my A+, and plan to go for CCNA after that. In the mean time as part of a homelab I wanted to create some minecraft servers using docker. I was quite overwhelmed, but your video is amazing! You explain each part and not just "show me how". I look forward to watching other videos of yours. Just want to say TYSM!!
An outstanding tutorial. All the main important moments are clearly explained and shown in practice in just an hour - a really great work! 10/10 👍 Definitely the best Docker introduction I've seen so far.
This was such a great course. It gave me everything I needed to no feel overwhelmed when getting started using docker. Thank you so much for making this free, it looked like it took a lot of effort to put it together as it is present so well.
Honestly this is the best and most up to date Docker crash course. It def gave me everything I needed for an upcoming project. It de-mystified all the jargon and everything is explained step by step in a good progression. I'll be checking out your online courses! Thank you so much for providing this!
This is so much better than any of the other Docker videos I tried. This is the minimum amount of info needed, love it! Any tutorial with less information is leaving out something essential.
The way you teach is beyond words. Thank you for touching the topic from the basic and covering all the aspects along!!
this course is gold! been postponing learning how to use docker and you made it simple to learn and how it works behind the scenes. Thanks for doing this!
This is one of the best docker beginner tutorial. Amazing easy to understand tutorial with simple explanations with animations and live demo. Thanks Nana
Been in industry for 2 decades. These 1 and 4 hours courses are a boon for a large segment of population. Thanks a lot !
WOW Nicely done! I looked several tutorials and docs and this is the first time I really understand the difference between docker containers and VMs! You are a great teacher
Nana your courses are so awesome. I really appreciate your pacing and in-depth explanation. I've not had the opportunity to work much with containers professionally, and your tutorials are really helping me out as I implement them first in my home lab, and later at my job. Your hard work is appreciated!
A great introductory course. Simple and concise. Slight correction for the Dockerfile section of the video. - *The commands in a dockerfile are not RUN/MAPPED in the container, only while BUILDING the image.* - _If it were, spinning up new containers would take longer as dependencies would have to be installed for each new container._ - Building a Docker image creates an object (the final layer) which specifies folder structures and contains all the necessary files i.e. base image files, installed package files, your program code and all other artifacts created as a result of the instructions in your Dockerfile. - Running the image creates a process (the container) to manage an ISOLATED instance with a folder structure and content continuing from where the image ended i.e. "run your code". This is why 2 containers based on the exact same image may have different contents at run time depending on what your code is doing to the file system: docker exec [ContainerId] ls . These underpin why a basic knowlege of Linux (file system and commands) is usually advised before learning Docker.
The best Docker Crash course I have seen till date , thoroughly enjoyed it. I have more than a decade experience in IT and I can safely say your way of teaching inspires me. Keep it up Nana, keep uploading more tech videos like this !! :)
Will definitely do, appreciate your amazing feedback! :)
I'm taking a DevSecOps class that touched on Docker, but I'm 13 minutes into this video and it's already clarifying some holes in my understanding. Thanks so much... I'm really looking forward to checking out your other videos.
You're the first person I found that managed to explain what a container actually is and what it does in a way that's clear.
Thanks for all the effort you've put on this video, Nana. It's super well made and helpful!
This is the best tutorial I could find so far that well answer the WHYs and WHATs questions in my head. Clear explanation and visualization. Many thanks!!
Great video! I love how you break everything down so well. I have only watched a few minutes but I am already getting things I kind of understood but not fully.
Thank you ALOT! i needed this. for the past 3 years i have postponed learning docker because i thought it was difficult. You explain it very well !
The absolute finest introduction to Docker on KZhead, period. Thank you kindly for sharing your knowledge.
Brilliant job of explaining this. The examples were realistic, the graphics were clear and helpful, and the pace was just right. Thank you!
Thank you for making this video. I've been waking up very early every morning to take your classes and have improved my skills. Knowledge is worth more than gold so you have done a great service. Also, I call my grandmother Nana and she is the coolest lady in the world.
I have never done or used docker in the past, but, I have been wanting to learn. Now I am motivated to go deeper into this subject. Great Job!!!!
Thank you Nana for this great intro tutorial. I am a complete newbie to Docker and after watching your video I think I understand docker pretty well. Thank you once again!
This tutorial is just awesome! I was struggling to build the whole Docker picture in my head, but this video just rock it! Thank you!
You are by far the easiest follow on KZhead. You are clear, efficient and energetic. Thank you for not being a dud 😊.
First, I watched your full course [3 hours] about docker. I. have learned so much things but I had some question marks in my mind especially about reasons. You explained docker more clearly and more convenient way in this video. My questions have been destroyed. Many thanks!
Amazing introduction to Docker, it was super clear and concise, thank you so much Nana ! 👏😎 Going to the 3 hours full course RN
Only tutorial i've ever watched. ive tried watching over like 10 this one had me hooked from the start. easy explanation- anyone doubting keep watching i learned a lot
That was awesome! Thank you for taking out time and creating this gem. I always struggled with Docker, but this video is super easy and you explained everything perfectly. Thank you Nana.
This is the best docker crash course I've seen so far, I was struggling with all the other videos and with yours I have 0 questions, I loved the part where you created the Dockerfile, you created in a way that it was super clear why you were using some specific commands, you got a new subscriber :)
What a great video, what a great tutorial. Congratulations. I've spent time trying to understand the fundamentals of Docker on other YT channels, but none of them explains that well. Thank you so much. I've subscribed and will work on your other videos!
Your explanations and animation graphics make learning so much fun. Thanks for doing so much for the community 👏🏻🙏🏻
Thanks for appreciating our efforts, means a lot! 💙
indeed , there is a strong correlation between explanations and animations .
But the audio could use some help. A little work toward reducing the echo would go a long way.
@@NetBandit70 it works just fine on my end.
@@TechWorldwithNana Can we get the slides Just for Quick Refresher whenever we go before interview
I’m new to docker and this tutorial is absolutely all you need to get started
Finally a tutorial that helps you understand what Docker actually is, how it works and also very practical. Although I couldn't get it to work with npm it was a step in the right direction for me. Maybe once an example in a tutorial would be possible, where a MySQL database is pulled as an image from docker-hub, then via Dockerfile a database and a table are created and lastly a record is written to the database. That would be great. But it would also be important for me to understand how I can get back to this data set, even if the container was stopped once ... (If I have understood it correctly, the container is reset with every stop, right?)
Great video. I’m exposed to docker every day and I’ve never properly understood it, but this video fills many of the gaps. Going to watch the full tutorial!
It would be great if you could make a video where you explain the different types of storage (nfs/distributed), how to address them on premise, it is recommended on the same servers as kubernetes or if it is better with another technology on separate servers, something similar in the cloud. The content you generate is amazingly good, it helps a lot, thanks nana!
What an explanation. Just amazing. I have an interview tomorrow, and this one-hour video cleared all my doubts. Thank you so much for this.
I am a curious learner and a novice in Docker. This tutorial is so amazing. it made me confident about Dockers right away!. Thx a Ton !!
Thank you so much for your charitable contributions Nana. The growing count of Subscribers you have speaks volumes as to the appreciation your audience has for you.
Excellent introduction to docker that goes into adequate details to get a good idea of where docker fits, how it works and how to use. Especially useful for a manager who wants to have knowledge, without having to go hands on.
You are a gifted teacher and you know how to support your teaching skill with visuals/presentations. It's like an ideal package we get from you. Absolutely impressive!
Your videos have been extremely helpful and informative. Appreciate for the effort and dedication you put into creating them. Thank you so much! 👏👏🙏
I've recently been learning more about Docker by taking courses and reading documentation, and honestly this whole video has been so helpful. Thank you!
This is EXACTLY what I needed. Clear, with perfect balance between theory and practice. Thank you so much!
Thanks for the feedback, appreciate it! :)
Awesome video. I've always heard of containers and had just an abstract idea of how it worked. In this 1h video, we have a real application working in a container and we can see how it works. Fantastic! I will keep following you. Thanks!
Enough information to be able to have a sensible discussion with IT. The most helpful tutorial I've ever used!
Absolutely Amazing crash course and love the way you've gone in to detail but just enough to get the flow moving and to cover such a huge topic in one hour. Thank you. Sadly, one key are many doing such tutorials seem to skim over is the concept of how the tool/application applies to the real world/SD lifecycle. This was attempted at 1.03 in the video but again, skimmed over I presume to keep the video to 1 hour however, I hope @Nana can take this feedback onboard and spend that last 10 minutes really showing how the tool/application is utilised in real world DEVOPS environments with examples. Aside from this, the key concepts within such a short video are clearly explained and a huge thank you once again for the hard work! Mo
Thanks for your great feedback! As mentioned in the video, I actually cover real world DevOps projects, examples and demos in our DevOps bootcamp.
@@TechWorldwithNana❤
Explanations are clear and easy to understand. I tried many times to learn Docker concepts but I succeeded this time. Thanks for the great explanations
I have been out of the development world for about a decade. This video was SUPER helpful in updating my brain to the current day about application virtualization. THANK YOU so much for creating this excellent presentation.
Just curious...were you away from IT completely for those 10 years? (I notice many people leave IT for a while and come back)
This session was definitely worth it, never came across anyone who explained the concepts for Dockers and containers so clearly on youtube... thanks Nana
This is an incredible video, an exemplar display of both technical and pedagogical competence. The animations are on point too, and combined with your way of exposing the whole learning process becomes so lightweight and pleasurable. Thank you for real 💎
Brilliant Hardwork for us ...No more words to say such course Nana.. complete Docker course learned in just 2 days over weekend ...Thank you 🎉❤
Wow, I can't believe it! I learned Docker in one hour. You are amazing!
Thank you so much for these tutorials, literally speechless about how great your explanation is and how you covered the workflow and use case, cheers!
This video is so great! I was trying to understand what Docker is for so long, as I am just starting to do some web dev stuff, the idea of a container and why we need it its hard to understand. This helps so much, thanks!
Nana, thank you so much for this awesome video. You have made it so easy to understand especially for some one who has no knowledge of what a container is. Loving your content on youtube.
You are a great teacher; thank you very much for making this video. It was the best hour I’ve ever spent learning something in my life. Every concept was extremely clear and is now firmly embedded in my mind.
This is excellent work ! So much clarity in teaching tells us how strong you're technically. Thank you for doing this. God bless you
Nana you have explained docker perfectly. Your explanations and animation graphics make it so much easy to understand. Before watching this video I have zero knowledge about docker but right now I feel like I have more than beginner knowledge about docker just because of your explanations style. Do keep up the good work and take love.
Best crash course! Each and every step was cleary explained here. Just built a basic django app image running locally with this tutorial learnings. Thanks Nana!
It's the first time I get to watch a docker content that's not boring! Thanks
This is actually nice. You can keep all the previous versions of your app image as well just in case if there is a bug in a new version, revert it back to the old image, quick and easy.
It's been an year since I follow your videos on YT. I will frankly say staring with K8s, I have no regret to keep going on !!
I wanted to learn Docker today and this crash course really helped me understand what docker is and how docker works in an hour! The crash course was great in terms of understanding and clarity which a beginner needs! Thanks a lot Nana! Will definetly recommend it to my peers and whoever wants to start learning Docker from scratch. ♥♥♥
I really loved the tutorial. Completed on a single sitting. Really great tutorial. Keep up the good work.
One of the best training clearly delivered at warp speed. Simply EXCELLENT!
You are a god! I've never seen an explanation so fluid like that before. Thank you very much for you splendid class! Thanks for helping the community
This is the video I've been looking for for years. It's a huge first step and it is for absolute beginners for sure. Thank you so much for making this amazing work a simple one.
Absolutely wonderful video Nana, this has given me perfect fundamental understanding of Docker and its necessity. Thank you 👍 for helping the tech community.
Definitely the best resource available to the field
Thanks for the feedback David, really happy to hear! 😊
Do you guys have tutoring programs for beginners???
Just one hour to gather all the knowledge I hardly built in many months! Congratulations.
Thank you so much for this. This video really helped me understand what docker is coming from a 1990s computer system knowledge.
First ever KZhead tutorial I started and finished. Amazing stuff Nana. Really appreciate your impact and teaching style
Haha the same here
This is brilliant. Thank you for putting this together. I'm now much more comfortable with Docker!
You are absoultely fantastic! This is the gentle introduction to Docker I was looking for. So thanks Nana.
Hands-down, one of the best explanation of Docker ever. God bless you!
I learnt docker in just one hour. this is amazing, your presentation and explanation with examples is awesome :)
Wow such an amazingly easy explanation with perfect presentation and images. My first video to watch here and I really appreciate the work!❤
I'm familiar with docker, but this video cought my attention for 100%. Brilliant explanation with practic examples. I would recomment it for newcomers. Thanks!
Very well explained - you have a great ability to convey information in plain, easy to understand terms. I didn't understand Docker before watching this but you totally demystified if for me! Thanks - Subscribed!
This is my first video from your channel. The docker basic video is simply brilliant and a gem session for all beginners. Learning is simply fun!
Best crash course I've found. was able to dockerize my first project. I feel like I understand the process and workflow a lot better too. thanks!
That's so great to hear Michael :)
After following so many tutorials, this one clicked for me. Thank you. Now, after Marc lambarti video and yours, I am confident on docker.
Thank you so much for these valuable courses which are getable in public domains like youtube! Please keep continuing this great work which would be a great meal for IT cravers!!
It helped a lot for beginners like me. The way you teach and explain through animations makes it understandable for all. Stay blessed ever ameen
49:16 love how you explained everything step by step and using "how and why" method
Thank you so much for an excellent, clearly explained intro to Docker! Seeing your diagrams makes a huge difference in conceptualizing what Docker is actually doing.
By far the best at explaining everything! Thank you so so much for all your content!
This is a great video!! Helped me to understand in overall how some pieces work and make it work in my local environment. Thanks for sharing your knowledge.
Great job, please continue to put the right questions and after answer them. I think there is the key for you awesome work!
Wow I could not hope for better get started. Tomorrow I’m watching full 3h course! Thanks for your job 🎉
Really enjoying this and finding it useful. One part that I think needs a bit more clarity is the "creating the Dockerfile". I would have liked to see the process of "how the app is integrated into a Docker image" (even just conceptually ) much earlier in the sequence (kept on wondering about this). When it was finally explained - it was a bit rushed, and also the Base Image was introduced en-route, which was a bit much to take in... Nana et al. - Many Thanks for this!!
Absolutely slayed the topic! Awesome explanation overall, no wonder your channel grew so fast!
This is really so good; you made the docker look so simple and I was able to gain a very good understanding of this topic. Thank You very much!!
