policies.kyverno.io/description: The volume of type `hostPath` allows pods to
|
|
use host bind mounts (i.e. directories and volumes mounted to a host path) in
|
|
containers. Using host resources can be used to access shared data or escalate
|
|
privileges. Also, this couples pods to a specific host and data persisted in
|
|
the `hostPath` volume is coupled to the life of the node leading to potential
|
|
pod scheduling failures. It is highly recommended that applications are designed
|
|
to be decoupled from the underlying infrastructure (in this case, nodes).
