The set of SCCs that admission uses to authorize a pod are determined by the user identity and groups that the user belongs to. Additionally, if the pod specifies a service account, the set of allowable SCCs includes any constraints accessible to the service account. Admission uses the following approach to create the final security context for the pod: • Retrieve all SCCs available for use. • Generate field values for security context settings that were not specified on the request. • Validate the final settings against the available constraints.
