红帽全球峰会9.2. Controlling pod security admission synchronization
You can enable automatic pod security admission synchronization for most namespaces.
System defaults are not enforced when the security.openshift.io/scc.podSecurityLabelSync field is empty or set to false. You must set the label to true for synchronization to occur.
Namespaces that are defined as part of the cluster payload have pod security admission synchronization disabled permanently. These namespaces include:
-
default -
kube-node-lease -
kube-system -
kube-public -
openshift -
All system-created namespaces that are prefixed with
openshift-, except foropenshift-operatorsBy default, all namespaces that have anopenshift-prefix are not synchronized. You can enable synchronization for any user-createdopenshift-*namespaces. You cannot enable synchronization for any system-createdopenshift-*namespaces, except foropenshift-operators.
If an Operator is installed in a user-created openshift-* namespace, synchronization is turned on by default after a cluster service version (CSV) is created in the namespace. The synchronized label inherits the permissions of the service accounts in the namespace.
Procedure
To enable pod security admission label synchronization in a namespace, set the value of the
security.openshift.io/scc.podSecurityLabelSynclabel totrue.Run the following command:
$ oc label namespace <namespace> security.openshift.io/scc.podSecurityLabelSync=true
You can use the --overwrite flag to reverse the effects of the pod security label synchronization in a namespace.
