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 :)
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
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
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!!
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
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.
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.)
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 ?
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!
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 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! =]
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!
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

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.

Thank you, I'm glad my video is so useful! :)
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!!!
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.
Wow ... Infinity thanks. After of this explanation, I understand very good how to use volumes correctly... Again... Thank you very much!

yeah, same thing :D
Great video.
Not sure why the official volume docs don't follow a similar structure like this.
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! :)
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! :)
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 best explanation of docker volumes on YT! The double indirection of named volumes threw me off, but your diagrams describe it perfectly.
it was really clear and concise
Love that you find it that way. Thank you. 🙂
The best explanation I have heard. Great job. Thank you
Thank you miss Nana! That was a very short and sweet explanation of a VERY complex subject!
Your videos are great! The official documents of Docker are so vague and incomprehensible, but you simplify and present these concepts so wonderfully.
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!
love the graphical representation, thank you
Nana is the best.... thank you for this brief yet comprehensive explanation.
can't believe i just found this channel now...thank you for the best explanation! subscribed!
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
Best resource about Docker Volumes on the web. God bless. Keep it up!
