## Mount propagation
{{< caution >}}
Mount propagation is a low-level feature that does not work consistently on all
volume types. It is recommended to use only with `hostPath` or in-memory `emptyDir`
volumes. See [this discussion](https://github.com/kubernetes/kubernetes/issues/95049)
for more context.
{{< /caution >}}
Mount propagation allows for sharing volumes mounted by a container to
other containers in the same pod, or even to other pods on the same node.
