I learn some news from Bug 1818893 Provide more informations from SCC anyuid and hostmount-anyuid $ oc get scc anyuid -o yaml allowHostDirVolumePlugin: false allowHostIPC: false allowHostNetwork: false allowHostPID: false allowHostPorts: false allowPrivilegeEscalation: true allowPrivilegedContainer: false allowedCapabilities: null apiVersion: security.openshift.io/v1 defaultAddCapabilities: null fsGroup: type: RunAsAny groups: - system:cluster-admins kind: SecurityContextConstraints metadata: annotations: kubernetes.io/description: anyuid provides all features of the restricted SCC but allows users to run with any UID and any GID. creationTimestamp: "2020-03-16T18:23:04Z" generation: 4 name: anyuid resourceVersion: "268421" selfLink: /apis/security.openshift.io/v1/securitycontextconstraints/anyuid uid: a66c7a1d-eda5-42ee-97e0-a814caee19cf priority: 10 readOnlyRootFilesystem: false requiredDropCapabilities: - MKNOD runAsUser: type: RunAsAny seLinuxContext: type: MustRunAs supplementalGroups: type: RunAsAny users: - system:serviceaccount:debugging:runasanyuid volumes: - configMap - downwardAPI - emptyDir - persistentVolumeClaim - projected - secret $ oc get scc hostmount-anyuid -o yaml allowHostDirVolumePlugin: true allowHostIPC: false allowHostNetwork: false allowHostPID: false allowHostPorts: false allowPrivilegeEscalation: true allowPrivilegedContainer: false allowedCapabilities: null apiVersion: security.openshift.io/v1 defaultAddCapabilities: null fsGroup: type: RunAsAny groups: [] kind: SecurityContextConstraints metadata: annotations: kubernetes.io/description: 'hostmount-anyuid provides all the features of the restricted SCC but allows host mounts and any UID by a pod.

But I don't have any idea in SCC anyuid, any comment are welcome OK... I dont known what happened $ oc get clusterversion version NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.3.10 True False 2m46s Cluster version is 4.3.10 $ oc edit scc hostmount-anyuid and put `- system:serviceaccount:default:nfs-client-provisioner` back to users lists I think it is not a reality to change SCC on the production environment when upgrading OCP, and it should provide a more clear and specific solution with users. *** This bug has been marked as a duplicate of bug 1821905 *** |
