- In which folder should the image downloaded by docker be placed?
- Docker images are stored in the /var/lib/docker/image folder by default. Docker stores images in a hierarchical manner: when a new image is downloaded, Docker checks whether it already exists in local storage. If it does not exist, Docker will download the image from the repository and store it in the image folder. You can change the storage location by setting the docker-root flag. Docker also provides other storage options such as distributed storage, remote storage, and custom storage drivers.
