How to set preferred_ip_protocol:ip4 in probe CRD

[erictarrence]

Right now my website is only accessible via ipv4 protocol, but looked at manifests/setup/0probeCustomResourceDefinition.yaml and https://docs.okd.io/4.11/rest_api/monitoring_apis/probe-monitoring-coreos-com-v1.html#spec-prober

None of the related parameters of preferred_ip_protocol:ip4 were found

Manual testing failed multiple times,The system prompts preferred_ip_protocol: There is a problem with the "ip4" parameter setting

cat block-probe-http.yaml

preferred_ip_protocol is a global setting of a blackbox_exporter and as such it is not configurable on Probe level. You need to configure it with blackbox_exporter configuration file - https://github.com/prometheus-operator/kube-prometheus/blob/main/manifests/blackboxExporter-configuration.yaml#L12
