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
Don't work with postgres containers. Asks for user. Pass error
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.
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 :)
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've spent hours trying to figure out all the variations I see for volumes. You just explained it excellently straight to the point
Thanks!!!
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 😊
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.
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! :)
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!
yeah, same thing :D
Thank you miss Nana! That was a very short and sweet explanation of a VERY complex subject!
Wow ... Infinity thanks. After of this explanation, I understand very good how to use volumes correctly... Again... Thank you very much!
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. 🙂
Great video.
Not sure why the official volume docs don't follow a similar structure like this.
I Like How Your Explanation Is Short And Direct. Very Helpful. THKS !
That's wonderful Mohamed. Happy to hear. Thank you. 🙂
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!
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 :)
Your work is admirable, your way of teaching is admirable simply great!!!!
great job, i watch like 3hours of your video, great explaination, nice job, thx
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! :)
Your videos are great! The official documents of Docker are so vague and incomprehensible, but you simplify and present these concepts so wonderfully.
Excellent Buddy.. clarified with one video..if possible try to explain on bind mounts
You’re my go to reference for learning keep up the great job!
can't believe i just found this channel now...thank you for the best explanation! subscribed!
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 ?
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. 🙂
The best explanation of docker volumes on YT! The double indirection of named volumes threw me off, but your diagrams describe it perfectly.
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
Was confused out of my tree focusing on the first type of volume, not realizing that their was 3. Great video.
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 🙂🙏
one of the best educators i have come across
Best resource about Docker Volumes on the web. God bless. Keep it up!
Thank you Ivan 😊
Awesome explanation! Thanks! 🥰🥰🥰
love the graphical representation, thank you
I was going to watch a several videos, but this one answered all my questions in 6 minutes. Thank you!
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!
Nana is the best.... thank you for this brief yet comprehensive explanation.
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 😇
the best tutorial for docker volumes out there
Thank you Kim 😊
Very clear specially as you mentioned WHY and WHEN we can specifically use volumes. Thank you a bunch!
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.
Thanks Raman. Will consider that for future content. Stay safe. 🙂
Clear and to the point, now I finally know what named volumes are for! Thanks!
Glad it was helpful John, thanks for your comment! :)
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!
Extremely helpful, thank you so much! You solved my hour long problem in 3 minutes
minimal and crisp, I loved it!
Thank you Matheus. Your support is much appreciated. 🙂
Very good presentation with relevant information !!!
Thank you very much !!!
You're welcome, glad the video is helpful :)
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! =]
Nana, You are the best. Thank you very much!
Best explanation I have already found.
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
Thank you! You made this very clear in the first minute or so. Exactly what I needed.
it was really clear and concise
Love that you find it that way. Thank you. 🙂
Thank you Nona!, this is a wonderful explanation
this is the best resource I've found for understanding containerization technologies. thanks for your hard work!
like always, great presentation. I wish we had you as a teacher in uni...
You have made docker very simple. Thank You for superb explanation.
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.
Sharp, To the point. Stay Blessed!
I'm surprised this vid has so few views. You explained really well and concisely.
Hi Uriel, thanks for your comment! I also think I deserved more views 😀Please share the content :)
One of the best explanation about docker volumes. Thank you Nana it's very helpful!
the section on how to define shared volumes in the docker compose file was really helpful. Thank you! I subscribed!
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.)
Thank you. I love you!
Thank you, this is very concise!
you are really awesome NANA, it was to the point. BTW i like your voice which kept me focused.
Thank you! Appreciate your feedback 😊
Very nice video. Are all containers located in the same path "/var/lib/CONTAINERNAME"???? Thanks
Great explanation! Thanks :)
Thanks for the video, stay inspired!
Thank you, you made it simple.
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 :)
Nice video, straight to the point. Can you explain how to manage containers with configuration files like MySQL and how about the permissions on Host machine to Containers ? Thanks
Excellent insight in short time. Great work. Expecting more learning & videos from you :)
Thank you! Please don't forget to share the knowledge with your friends. 🙂
Fantastic video - great explanation with just enough visual!
Thanks a lot Doug! Really happy you like my explanation and visuals :)
perfectly explained. thank you so much.
great video, thank you.
Thanks a lot for this video! Exactly what I needed to my project :D
I hope you aced your project Nic. Best of luck! 🙂
Thank you very much !
Nana, for me, if im stuck in docker, i just land up to your channel !
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 :)
Thanks a lot for this interesting video !!!!!!
Thanks! explained very well in a very short amount of time.
Brilliant video once again Nana! Thanks
Thanks!
Great video to help me understand volumes. Now... how do I find the volume on the Windows10 host to modify the persistent data?
Another great video by Nana where she explains things so well. Thanks so much! :)
Great job Nana. Thank you
Actually insanely well explained. Thank you, will subscribe.
very well explained. clear and crispy way...:)
I don't know about crispy, but it makes me think about food. 😇 But yes, thank you Surendhiran, this is much appreciated.
Thank you Nana, Is it possible to explain a little bit about how to rename a volume? Thanks
hey nana did you have a more in depth video of this topic? thanks for all your content
Thank you Nana, this was brilliant
Ahhh... clarity. Thank you.
Yes, it's the best way to impart knowledge. 😇
These videos are 🔥!
Thanks for making them :)
Clear, simple and nice :) Perfect explanation !
In docker-compose you should use "volumes: db-data: " instead of "volumes: db-data " (with colon)
you are the best, really like your tutorials
superbly explained 👍🏽
great !!! how can I define a specific host directory? for example a NAS NFS
Perfect explanation! Clear, well paced and to the point!
Thank you 🙏
thank you for the great video. A question regarding the named volumes: How can we share data from the host with the container, but using named volumes? For that purpose, I assume, "Host Volume" (type 1) is more suitable, correct?
Nicely explained. multiple path volume can be created using docker compose
Container context which multiple folder will be automatically created that named inside context?
