policies.kyverno.io/description: Linux allows defining fine-grained permissions using
|
|
capabilities. With Kubernetes, it is possible to add capabilities that escalate the
|
|
level of kernel access and allow other potentially dangerous behaviors. This policy
|
|
enforces that pods cannot add new capabilities. Other policies can be used to set
|
|
default capabilities.
