uploaded file duplication in host and container by laravel file storage

I configured the laravel application in the docker container on the Ubuntu server. Files uploaded with laravel file storage and linked php artisan storage:link. Files uploaded to laravel storage are available in both container and host.
Doesn't that mean duplication of the uploaded files, for example it
exists in docker container also in project source code in ubuntu
server?
I know that best way of storing uploaded files is some external space like aws s3, digitalocean spaces...
No there is no duplication. The files only exist once on the host machine and are mounted in the container as views (read/write)

How to access local files from docker image running springboot using the file URI?

I have a Spring Boot application running in a docker image. We can access local API's using host.docker.internal, so is there any way to access local files using its URL, i.e. for eg:
file:///Users/ayush.singhal/Downloads/arguments.csv
I know about accessing the file by mounting the volume, but I am trying to do it from internal program itself that is running in the docker image.
You can add a mount point using "volumes" in the docker-compose file that will point to a folder in the host system. By default, docker isolates the container from everything else.

How to access a file of Mac from Docker container

I am running robot framework (Selenium based) testing inside a Docker container. But I need to access files outside the Docker container (in Mac).
I have tried providing absolute path of the Mac but Docker refers it's core folder as the root folder.
I found below links for Windows, but not for Mac.
Docker - accessing files inside container from host
Access file of windows machine from docker container
one approach is copy your files inside docker container at creation time, but if your files updates by another service on host, and it needs to access them too, just mount it like below.
docker run -d --name your-container -v /path/to/files/:/path/inside/container containername:version
this way files on the host machine mounts into docker container and the user inside container can access them.

Where are images stored for Docker EE on Windows Server 2016 and how do I change its location?

Im running the latest Docker EE on server 2016, where are my images and containers stored on disk?
Running docker info I see this:
Docker Root Dir: C:\ProgramData\docker
I have a csv volume mounted on the server and I want docker to use that volume for images and containers.
Where do I configure where docker stores and runs images and containers?
This can be controlled with the --graph option to dockerd.exe or by similarly modifying the C:\ProgramData\Docker\config\daemon.json file. Details here: https://learn.microsoft.com/en-us/virtualization/windowscontainers/manage-docker/configure-docker-daemon#configure-docker-with-configuration-file

docker: possible to create a single file with binaries and packages installed?

Basically I want to create a "snapshot" of my current Ubuntu box, which has compiled binaries and various apt-get packages installed on it. I want to create a docker instance of this as a file that I can distribute to my AWS ec2 instances which will be stored on S3 bucket that will be mounted by the ec2.
Is it possible to achieve this, and how do you get started?
You won't be able to take a snapshot of a current box and use it as a docker container, but you can certainly create a container to use on your EC2 instances.
Create a Dockerfile that builds the system exactly as you want it.
Once you've created the perfect Dockerfile, export a container to a tarball
Upload the tarball to S3
On your EC2 instances, download the tarball and import it as a Docker container.
Are you planning to use something like s3fs to mount an S3 bucket? Otherwise you can just copy the tarball from your bucket either as a userdata boot script or during a chef/puppet/ansible provisioning step. Depends how you want to structure it.
