<!-- overview -->
On-disk files in a container are ephemeral, which presents some problems for
non-trivial applications when running in containers. One problem
is the loss of files when a container crashes. The kubelet restarts the container
but with a clean state. A second problem occurs when sharing files
between containers running together in a `Pod`.
non-trivial applications when running in containers. One problem occurs when
a container crashes or is stopped. Container state is not saved so all of the
files that were created or modified during the lifetime of the container are lost.
During a crash, kubelet restarts the container with a clean state.
Another problem occurs when multiple containers are running in a `Pod` and
need to share files. It can be challenging to setup
and access a shared filesystem across all of the containers.
The Kubernetes {{< glossary_tooltip text="volume" term_id="volume" >}} abstraction
solves both of these problems.
Familiarity with [Pods](/docs/concepts/workloads/pods/) is suggested.
