The directory on the physical machine is a regular folder in the host's filesystem where files are stored.

A Docker volume is a special mechanism for storing data that:

  • Is isolated from the container’s lifecycle (data remains even after the container is deleted).
  • Is managed by Docker and optimized for working with containers.
  • Can be mounted into one or more containers simultaneously.

Unlike simple mounting of a host directory, volumes provide better portability and data management. For example, a volume can be created with the command:

docker volume create my_volume

And used in a container with:

docker run -v my_volume:/app/data my_image

Thus, volumes are convenient for storing persistent data, while host directories are useful for quick access to local files, but with less isolation.
