I have been trying to figure out where docker is trying to store images when I am doing a docker pull for windows containers but am unable to find the exact location.
Even though I have created Junction links for all the docker files I could find in the C Drive and also configured Hyper-V to store everything in the external drive, when I do a docker pull, it still starts downloading in the C drive which eventually fails as I have no space available there.
Can someone help me here please ? I am trying to do a POC for windows containers and cannot pull down the large images :(
Thanks in advance,
Vishal

I'm completely new to docker and ddev and I have just started learning things. My main purpose to use Docker & Ddev is to work on my CMS projects. However, I noticed that by default the docker gets installed in C drive (in my case its almost full). Therefore, I want to learn how to create my projects in D drive using DDEV.
For example I would like to have them organized in one single folder like
D://Myprojects\Drupalsites\Mysite1
Something like that.
How do I do that?
Your problem isn't DDEV and your projects, it's docker using up your space, at at least as far as I understand your question.
So what you're really wanting to do is to move your Docker WSL2 data distro over to the new drive. As far as I know Docker and WSL2 don't provide a simple way to do this, but these two links will tell you how you can do it.

How can I change the location of docker images when using Docker Desktop on WSL2 with Windows 10 Home?
I have not tried this.
One note though: Most people these days are doing the recommended thing and running DDEV inside WSL2 (in /home/<youruser>). But if you already have trouble with disk space with WSL2, you're going to have trouble with that as well. But WSL2 should be your future, see https://ddev.readthedocs.io/en/stable/#installation-or-upgrade-windows-wsl2
I will start by saying I am a complete newbie to docker. I have created a docker image for a project locally, but other people in our organization will need to do the same thing. Instead of having them copy the folder locally, I would want them to able to create the image on the folder on our network drive.
I can't seem to cd into the network drive - do anybody know of any guides to do what the question asks, or perhaps give a brief explanation of what I should be searching for (I have tried searching online, but can't seem to find a guide on how to create a docker image on a network folder, perhaps I'm using the wrong terminology)?
I am new to docker. So what I want to have is a pgadmin container which I can pull and have always my configs and connections up to date. I was not really sure how to do that, but can I have a Volume which is alsways shared for example on my Windows PC at home and on work? I couldt find an good tutorial for that and dont know if that makes sense. Lets say my computer would be stolen I just want to install docker and my images and fun.
What about a shared directory using DropBox ? as far as i know that the local dropbox directories always synced with the actual dropbox account which means you can have the config up to date for all of your devices.
Alternatively you can save the configuration - as long as it does not contain sensitive data - on a git repository which you can clone it then start using it. Both cases can be used as volumes in docker.
That's not something you can do with Docker itself. You can only push images to DockerHub, which do not contain information that you added to a container during an execution.
What you could do is using a backup routine to S3 for example, and sync your 'config and connections' between your docker container running on your home PC and work one.
I'm new to docker and am currently working on dockerizing a simple ELK Stack application at work. I've seen several tutorials on how to do this, however my biggest issue is that I can't use just any existing docker image, as this is corporate code. So, from my understanding, I'll need dockerize/create 3 separate images of ELK from artifacts that we have currently available internally. My current approach so far has been to get the rpms (using RHEL7), create a dockerfile to install/expose them ect.
Reason for my approach: I am working behind a corporate firewall and proxy and don't know if downloading an official docker image is possible nor if it is compliant
So far unsuccessful, but does anyone have experience doing this?
Thanks in advance!
It seems your env can not access through internet to docker registry to download docker images right ? So you just want to get the docker image related with EFK, refer How to copy Docker images from one host to another without using a repository for copy the images to your env.
this might seems a stupid question, but here I am :
I'm running Ubuntu 16.04 and managed to install windows 10 in dual boot.
Running docker exclusively in linux so far, I decided to give it a try on Windows 10.
As I already downloaded several docker images on my Linux system, I'm willing to have a "shared" like development environment. I must admit this would be a waste of time and disk space to download Docker images I already downloaded before (on linux) on my fresh windows install.
So my question is simple : Can I use my linux images / containers on windows. I'm thinking of something like a global path variable pointing to my linux images to configure on docker windows.
Any idea if this is possible, and if yes, the pros and cons and the caveats ?
Thanks for helping me on this one.
Well i would suggest to create your local registry and then push these images there and pull it in your windows docker.
Sonatype nexus(artifact storage repository) can be used to store your docker images. Check if this helps.
I guess it's not possible to share the same folder (to reduce disk usage) since the stored files are totally different:
Under Windows the file is:
C:\Users\Public\Documents\Hyper-V\Virtual hard disks \MobyLinuxVM.vhdx
the vhdx extension is specific to MS systems.
and under linux it consist of 2 files:
/var/lib/docker/devicemapper/devicemapper/data
/var/lib/docker/devicemapper/devicemapper/metadata
see here for details
Where are Docker images stored on the host machine?
The technology under this is to have a specific fileSystem optimal for docker. Even if they used the same fileSystem storage, it wouldn't be a good idea imho.
If the purpose is only to gain time for resintalling, just dump all the images from on system, and re-pull them on the other one.
docker images --format "{{.Repository}}" > image-list.txt
then loop on the other OS
while read p; do
docker pull $p
done < image-listtxt
