Additional information: 

This affects 4.5, 4.6, 4.7 alike. When applying the CLI example:
~~~
apiVersion: "logging.openshift.io/v1"
kind: "ClusterLogging"
metadata:
  name: "instance" 
  namespace: "openshift-logging"
spec:
  managementState: "Managed"  
  logStore:
    type: "elasticsearch"  
    retentionPolicy: 
      application:
        maxAge: 1d
      infra:
        maxAge: 7d
      audit:
        maxAge: 7d
    elasticsearch:
      nodeCount: 3 
      storage:
        storageClassName: "<storage-class-name>" 
        size: 200G
      resources: 
        requests:
          memory: "8Gi"
      proxy: 
        limits:
          memory: 256Mi
        requests:
           memory: 256Mi
      redundancyPolicy: "SingleRedundancy"
  visualization:
    type: "kibana"  
    kibana:
      replicas: 1
  curation:
    type: "curator"
    curator:
      schedule: "30 3 * * *" 
  collection:
    logs:
      type: "fluentd"  
      fluentd: {}
~~~

~~~
$ oc apply -f clo.yaml
The ClusterLogging "instance" is invalid: spec.logStore.elasticsearch.proxy.resources: Required value
~~~

Instead, we change this to:
~~~
apiVersion: "logging.openshift.io/v1"
kind: "ClusterLogging"
metadata:
  name: "instance" 
  namespace: "openshift-logging"
spec:
  managementState: "Managed"  
  logStore:
    type: "elasticsearch"  
    retentionPolicy: 
      application:
        maxAge: 1d
      infra:
        maxAge: 7d
      audit:
        maxAge: 7d
    elasticsearch:
      nodeCount: 3 
      storage:
        storageClassName: "<storage-class-name>" 
        size: 200G
      resources: 
        requests:
          memory: "8Gi"
      proxy:
        resources:
          limits:
            memory: 256Mi
          requests:
            memory: 256Mi
      redundancyPolicy: "SingleRedundancy"
  visualization:
    type: "kibana"  
    kibana:
      replicas: 1
  curation:
    type: "curator"
    curator:
      schedule: "30 3 * * *" 
  collection:
    logs:
      type: "fluentd"  
      fluentd: {}
~~~

Thanks,
