Note than on Windows and Mac, Docker runs Linux containers in a virtual environment..
What is difference between Docker container and image?
Images can exist without containers, whereas a container needs to run an image to exist. Therefore, containers are dependent on images and use them to construct a run-time environment and run an application. The two concepts exist as essential components (or rather phases) in the process of running a Docker container.
Where are Docker volumes stored?
In layman’s terms, volumes are external storage areas used to store data produced by a Docker container. Volumes can be located on the docker host or even on remote machines. Containers are ephemeral, a fancy way of saying that they have very short lives.
Which file system service is used by Docker?
The btrfs and zfs storage drivers are used if they are the backing filesystem (the filesystem of the host on which Docker is installed). These filesystems allow for advanced options, such as creating “snapshots”, but require more maintenance and setup.

Where is Docker container data stored?
Docker volumes Configuration data on volumes is stored in the /var/lib/docker/volumes folder, with each sub-directory representing a volume name based on a universal unique identifier (UUID). The data itself is stored in the /var/lib/docker/vfs/dir folder (again based on UUID name).
Where does Docker pull images from?
Docker HubBy default, docker pull pulls images from Docker Hub. It is also possible to manually specify the path of a registry to pull from. For example, if you have set up a local registry, you can specify its path to pull from it.

What is Docker pull command?
The docker pull command serves for downloading Docker images from a registry. By default, the docker pull command pulls images from Docker Hub, but it is also possible to manually specify the private registry to pull from.
Where the Docker images are stored?
The heaviest contents are usually images. If you use the default storage driver overlay2, then your Docker images are stored in /var/lib/docker/overlay2 . There, you can find different files that represent read-only layers of a Docker image and a layer on top of it that contains your changes.
