Guide to Docker Volumes – How to Use Volumes with Examples

Docker volumes provide persistent storage for containers and are managed by Docker independently from the containers themselves. They can be mounted to multiple containers simultaneously, remain accessible after the containers they're attached to have stopped, and can be centrally managed using the Docker CLI. Volumes should be used when a container requires permanent storage to save new or modified files. This is especially important for stateful applications like databases and file servers. Using volumes ensures that critical data persists even after a container failure or restart.
