OpenShift provides multi-tenant networking isolation (using Open vSwich and
|
|
|
vXLAN), to segregate network traffic between containers belonging to different
|
|
|
tenants (users or applications) while running on a shared cluster. Red Hat also
|
|
|
works with 3rd-party SDN vendors to provide the same level of capabilities
|
|
|
integrated with OpenShift. OpenShift SDN is included a part of OpenShift
|
|
|
subscription.
|
|
|
|
|
|
OpenShift supports Kubernetes NetworkPolicy. Administrator must configure
|
|
|
NetworkPolicies if desired.

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.

|

|
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.
