CertificateSigningRequest objects provide a mechanism to obtain x509 certificates by submitting a certificate signing request, and having it asynchronously approved and issued.
Kubelets use this API to obtain:
client certificates to authenticate to kube-apiserver (with the "kubernetes.io/kube-apiserver-client-kubelet" signerName).
serving certificates for TLS endpoints kube-apiserver can connect to securely (with the "kubernetes.io/kubelet-serving" signerName).
This API can be used to request client certificates to authenticate to kube-apiserver (with the "kubernetes.io/kube-apiserver-client" signerName), or to obtain certificates from custom non-Kubernetes signers.
PodSecurityPolicyReview checks which service accounts (not users, since that would be cluster-wide) can create the PodTemplateSpec in question.
Compatibility level 2: Stable within a major release for a minimum of 9 months or 3 minor releases (whichever is longer).
PodSecurityPolicySelfSubjectReview checks whether this user/SA tuple can create the PodTemplateSpec

PodSecurityPolicySubjectReview checks whether a particular user/SA tuple can create the PodTemplateSpec.

RangeAllocation is used so we can easily expose a RangeAllocation typed for security group
Compatibility level 4: No compatibility is provided, the API can change at any point for any reason. These capabilities should not be used by applications needing long term support.
SecurityContextConstraints governs the ability to make requests that affect the SecurityContext that will be applied to a container. For historical reasons SCC was exposed under the core Kubernetes API group. That exposure is deprecated and will be removed in a future release - users should instead use the security.openshift.io group to manage SecurityContextConstraints.
Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).
ServiceAccount binds together: * a name, understood by users, and perhaps by peripheral systems, for an identity * a principal that can be authenticated and authorized * a set of secrets
