Windows pods offer the ability to run HostProcess containers which enables privileged
|
|
access to the Windows node. Privileged access to the host is disallowed in the baseline
|
|
policy. HostProcess pods are an alpha feature as of Kubernetes v1.22. This policy ensures
|
|
the `hostProcess` field, if present, is set to `false`.
