What is the purpose of SecurityContextConstraints in OpenShift?

SecurityContextConstraints define how a pod can run in OpenShift by specifying security-related settings for pods and containers. They control aspects like which users and groups can run, whether privileged mode is allowed, SELinux context, capabilities, runAsUser/runAsNonRoot strategies, and how the filesystem and host resources can be accessed (for example, allowed host paths and readOnlyRootFilesystem). When a user creates a pod, OpenShift checks the pod’s securityContext against the SCCs bound to that user or service account; only if the pod complies with an allowed SCC is it permitted to run. This is why this option best describes the purpose: OpenShift uses SecurityContextConstraints to enforce security restrictions on pods. Network policies govern pod-to-pod traffic, not securityContextConstraints; resource quotas manage resource usage in namespaces; storage classes define dynamic provisioning of storage.
