How do I persist volume in docker?
Persist the todo data
- Create a volume by using the docker volume create command.
- Stop and remove the todo app container once again in the Dashboard (or with docker rm -f ), as it is still running without using the persistent volume.
- Start the todo app container, but add the -v flag to specify a volume mount.
How do I create a volume in a docker container to store data?

What is NFS in Kubernetes?
Network File System (NFS) is a standard protocol that lets you mount a storage device as a local drive. Kubernetes allows you to mount a Volume as a local drive on a container.

Can we delete Docker volumes?

What is Docker data storage?
A Docker volume permits data to be stored in a container outside of the boot volume (but within the root file system) and can be implemented in two ways. A container can be created with one or more volumes by providing a share name passed to the “-v” switch parameter (for example, /dockerdata).
