How does Docker Volume help manage data in containers?

Answer from AI
Docker Volume is a mechanism for storing data outside the container, allowing data to be preserved and managed independently of the container's lifecycle.
Advantages of using Docker Volume:
- Data persists even after the container is deleted.
- Facilitates easy data exchange between multiple containers.
- Provides better performance and security compared to mounting host directories.
Example of usage:
docker volume create mydata
docker run -v mydata:/app/data myimage
In this example, a volume named mydata is created and mounted into the container at the path /app/data. All data written to this directory will be stored in the volume and accessible when running other containers with this volume.
