+ Review SCCs:

+
+ Use OpenShift's Security Context Constraint feature, which has been contributed
+ to Kubernetes as Pod Security Policies. PSPs are still beta in Kubernetes 1.10.
+
+ OpenShift ships with two SCCs: restricted and privileged. The two default SCCs
+ will be created when the master is started. The restricted SCC is granted to
+ all authenticated users by default.
+
+ All pods are run under the restricted SCC by default. Running a pod under any
+ other SCC requires an account with cluster admin capabilities to grant access
+ for the service account.
+
+ SecurityContextConstraints limit what securityContext is applied to pods and
+ containers.

+ OpenShift ships with two SCCs: restricted and privileged. The two default SCCs
+ will be created when the master is started. The restricted SCC is granted to all

+
+ Similar scenarios are documented in the SCC
+ documentation, which outlines granting SCC access to specific serviceaccounts.
+ Administrators may create least-restrictive SCCs based on individual container
+ needs.
+
+ For example, if a container only requires running as the root user, the anyuid
+ SCC can be used, which will not expose additional access granted by running
+ privileged containers.
