|
The seccomp profile in the Restricted group must not be explicitly set to Unconfined
|
|
but additionally must also not allow an unset value. This policy,
|
|
requiring Kubernetes v1.19 or later, ensures that seccomp is
|
|
set to `RuntimeDefault` or `Localhost`. A known issue prevents a policy such as this
|
|
using `anyPattern` from being persisted properly in Kubernetes 1.23.0-1.23.2.
