Wow! this was actually the best explanation for docker volume mapping i have stumbled upon so far. You really made it so easy to understand. Thank you Nana.
Hi there nana, great video. I'm new to docker and containers in general, I wanted to know, do you have to manually create the path in the container (in this case /var/lib/mysql/data) your mapping to, and how do you go about doing it ? Thanks in advance.
Hi nana, could tell me what is the maximum capacity of volume size by default in docker if we didnt mention limit to it. As well as how i can find that ? Thanks in advance
As a beginner i read volumes concept in docker document but didn't understood clearly but with your tutorial it understood clearly,way you delivered this concept is awesome . "short and sharp" teaching. Thank you so much :)
replication? which part? Are you referring to the volume creation with a path as replication since the data being saved inside the container is also being saved to that particular folder path as well as it's being mounted the moment the image is recreated.
You are a genius in the way you break down complex topics that the layman can understand and follow crystal clear. This video is better than alot of paid courses out there. Your explanation is a lot clearer than the official docs too. Although it did not directly solve the problem I had it sure did make me more confident and pointed me in the right direction to eventually solving the problem. Thank you for your contribution to humanity and also potentially saved my job!
Wow thank you so much, couldn't understand the volumes any better, despite I watch dozens of other video tutorials here, none of them made it this easy to visualise the entirety of the whole concept in my head, you are a star :)
The editing efforts you are putting to create videos on docker and kubernetes is commendable!! I have noticed how each sub-topic is clearly mentioned with the title when we slide the video forward!!
wow. this short video has helped mde out a bunch in understanding what is going on in our docker environment. Once I watch more of your videos I'm sure I will have a good understanding of docker! Thanks a lot!
Good point at 1:55 . Thank you. I could not understand why there were volumes inside containers and outside. For the sake of copying and saving))) Clear
Question: In the end of this tutorial (around 5:00) , you explain the docker compose methodology for creating a volume that is used cross-container. My question is : what if those containers are created across different hosts ? How can / should we ensure that the physical folder is shared by the different container hosts ?
I always test it by restarting the docker container, if the container does not need to be reinstalled, that means it was mapped correctly and its working
Exactly what i needed, last thing I want is a video that drags out for 15 to 21 minutes when I just need to know what the tutorial im following is doing
Love the content. 2 questions: 1) How relevant for DevOps is to know the internals of Docker volumes? i.e. Unified Filesystem and storage drivers. 2) How relevant is configuring docker volumes (w/ command-line arguments)?
1) DevOps on premise must know what is going on, to diagnose and be in control what's happening. There cannot be cases, especially on live environment, when devops says he/she does not know what's going on - such minimum knowledge like storage drivers is required, the rest you get from stackoverflow, google etc. 2) Does not matter. Use compose for smaller things, and Kubernetes for large scale (CI, live etc.)
Thanks for the breakdown, I've been stuck on a volume issue for a while now. Turns out I misunderstood one of the volume types which your video cleared up! =]
Hey Nana, this video was very clear and helpful. Can you make a video about different types of mount as well explaining difference b/w bind and volume mount.
This was the biggest question I had. This is also something that always should be mentioned in beginner tutorials, sadly it almost never is. Which make it really hard to understand containers as a newcomer.
Thanks a lot for this series of videos -- they are extremely useful, as someone who never had experience with docker before, now I have a good idea of what a developer workflow with docker looks like!

Don't work with postgres containers. Asks for user. Pass error
Thanks!
I really like the way you deliver information in a short, sharp way. It really cuts through some of the complexities of the subject matter
Thanks Pete for that positive feedback! :)
Exactly.

Thank you, I'm glad my video is so useful! :)
Not only she explained what volumes are , she even explained how to replicate a database using volumes in just 6 minutes!!!! HOLY MOLY . Ty !
replication? which part? Are you referring to the volume creation with a path as replication since the data being saved inside the container is also being saved to that particular folder path as well as it's being mounted the moment the image is recreated.
I usually don’t comment on TH-cam videos, but your content truly deserves to be appreciated. I’ll definitely share your channel with my coworkers.
Thank you so much! Appreciate your comment 😊

for your contribution to humanity and also potentially saved my job!
yeah, same thing :D
I've spent hours trying to figure out all the variations I see for volumes. You just explained it excellently straight to the point
Thanks!!!
Wow, this video just made everything make sense! I’ve been losing hours of my week trying to figure out these freaking volume save paths. Thank you!
And I have been losing years everytime I come back to volumes. Now it's crystal clear.
Wow thank you so much, couldn't understand the volumes any better, despite I watch dozens of other video tutorials here, none of them made it this easy to visualise the entirety of the whole concept in my head, you are a star :)
Wow thanks, very happy to hear that my video is so helpful! Would appreciate your support by sharing my videos or subscribe :)
Wow ... Infinity thanks. After of this explanation, I understand very good how to use volumes correctly... Again... Thank you very much!
Excellent lesson! Easily digestible and thorough. I was confused about named volumes in docker compose files, this totally cleared it up in a hurry.
Cool thanks a lot Jaime! :)
The best explanation of docker volumes on YT! The double indirection of named volumes threw me off, but your diagrams describe it perfectly.
Thank you miss Nana! That was a very short and sweet explanation of a VERY complex subject!
can't believe i just found this channel now...thank you for the best explanation! subscribed!
I Like How Your Explanation Is Short And Direct. Very Helpful. THKS !
That's wonderful Mohamed. Happy to hear. Thank you. 🙂
Great way to slip in the commands along with the high level explanation! Usually you only get one or the other in tutorial videos. Thanks!
Awesome Rafa! Glad to be of help. 🙂
The editing efforts you are putting to create videos on docker and kubernetes is commendable!! I have noticed how each sub-topic is clearly mentioned with the title when we slide the video forward!!
Thank you so much Pallav, happy one can notice the efforts I put into my videos and it's appreciated 🙂🙏
it was really clear and concise
Love that you find it that way. Thank you. 🙂
I was going to watch a several videos, but this one answered all my questions in 6 minutes. Thank you!
Your videos are great! The official documents of Docker are so vague and incomprehensible, but you simplify and present these concepts so wonderfully.
You are always super Nana in explaining the concepts really simple words. It works like a charm every time.
You are great.
I appreciate the compliment. Thank you. 🙂
After hanging around dozens of tutorials at last I got the Volumes puzzle solved here. Thank you!
You're welcome, happy to hear my video is so helpful! :)
Nana is the best.... thank you for this brief yet comprehensive explanation.
Your work is admirable, your way of teaching is admirable simply great!!!!
I really liked the way you described the topic. Nice interactive slideshow. I saw many volume description videos and by far this is one of the best.
Thanks a lot, really happy to hear!
Seen so many videos but not satisfied with any of them. Your way of presentation is awesome. Keep doing. Good luck👍
Thanks a lot Kumar 😇

Good point at 1:55 . Thank you. I could not understand why there were volumes inside containers and outside. For the sake of copying and saving)))
Clear
the section on how to define shared volumes in the docker compose file was really helpful. Thank you! I subscribed!

My question is : what if those containers are created across different hosts ? How can / should we ensure that the physical folder is shared by the different container hosts ?
The best explanation I have heard. Great job. Thank you

Great video.
Not sure why the official volume docs don't follow a similar structure like this.
Exactly what i needed, last thing I want is a video that drags out for 15 to 21 minutes when I just need to know what the tutorial im following is doing
Thanks Shaun!
Excellent Buddy.. clarified with one video..if possible try to explain on bind mounts
Thank you Nana, 5+ years later and still helping dudes like me to understand things!
Very clear specially as you mentioned WHY and WHEN we can specifically use volumes. Thank you a bunch!
this is the best resource I've found for understanding containerization technologies. thanks for your hard work!
You’re my go to reference for learning keep up the great job!
One of the best explanation about docker volumes. Thank you Nana it's very helpful!
great job, i watch like 3hours of your video, great explaination, nice job, thx
Best resource about Docker Volumes on the web. God bless. Keep it up!
Thank you Ivan 😊
Thank you! You made this very clear in the first minute or so. Exactly what I needed.
Love the content. 2 questions:
1) How relevant for DevOps is to know the internals of Docker volumes? i.e. Unified Filesystem and storage drivers.
2) How relevant is configuring docker volumes (w/ command-line arguments)?
1) DevOps on premise must know what is going on, to diagnose and be in control what's happening. There cannot be cases, especially on live environment, when devops says he/she does not know what's going on - such minimum knowledge like storage drivers is required, the rest you get from stackoverflow, google etc.
2) Does not matter. Use compose for smaller things, and Kubernetes for large scale (CI, live etc.)
Extremely helpful, thank you so much! You solved my hour long problem in 3 minutes
one of the best educators i have come across
Clear and to the point, now I finally know what named volumes are for! Thanks!
Glad it was helpful John, thanks for your comment! :)
I used this for my project. Thanks Nana :)
How did it work out for you Jesho? I hope it worked wonders! All the best. 🙂
@@TechWorldwithNana yes it was :) I'm exploring kubernetes now. Will come back with doubts in the coming days. Hope you can help :)

good introduction, at least now I know that named volume should be used in production, in case someone ask me this in an interview 😀
Thanks, glad it was helpful :)
Excellent video, really quick to the point

Thank you, you made it simple.
Just what i need to do in production and what i want to explain to my team. Awesome 👍
Thank you so much for the info ! I have a question can we use docker volume instead of installing packages each time in docker file
