What is a docker volume?

Volumes are the preferred mechanism for persisting data generated by and used by Docker containers. While bind mounts are dependent on the directory structure and OS of the host machine, volumes are completely managed by Docker. You can manage volumes using Docker CLI commands or the Docker API.

How does volume work in Docker?

You can create a volume explicitly using the docker volume create command, or Docker can create a volume during container or service creation. When you create a volume, it is stored within a directory on the Docker host. When you mount the volume into a container, this directory is what is mounted into the container.

What is the difference between a docker volume and a Kubernetes volume?

A Kubernetes volume, unlike the volume in Docker, has an explicit lifetime – the same as the Pod that encloses it. Consequently, a volume outlives any Containers that run within the Pod, and data is preserved across Container restarts. Of course, when a Pod ceases to exist, the volume will cease to exist, too.
