Description of problem:
The communication matrix project aims to automatically generate an accurate and up-to-date communication flows matrix that can be delivered to customers as part of product documentation for all ingress flows of OpenShift (see documented communication matrix examplehttps://docs.openshift.com/container-platform/4.16/installing/install_config/configuring-firewall.html#network-flow-matrix_configuring-firewall).
The communication matrix consists of the cluster's endpoint slices which are created automatically for every service on the cluster. Your operator includes some open ports with missing services, and by that there are missing endpoint slices. To solve this issue, please add service to the following ports: 9107 (worker and master nodes, TCP protocol), 10256 (worker and master nodes, TCP protocol), 6081 (worker and master nodes, UDP protocol).
Version-Release number of selected component (if applicable):

How reproducible:
Compare between endpoint slices to open ports.
Steps to Reproduce:
1. Get endpoint slices: run the following command: `oc get endpointslices -n <operator's-namespace>`

2. Get open ports: Make sure the `ss` command is available within your pod - if not use the following command to install iprune2 on your pod: `dnf install -y iproute` In order to get ports using TCP protocol run from your node: `ss -anpltH` In order to get ports using UDP protocol run from your node: `ss -anpluH`

3. Compare the ports between the outputs.
Actual results:
The following ports are missing endpoint slices: 9107 (worker and master nodes, TCP protocol), 10256 (worker and master nodes, TCP protocol), 6081 (worker and master nodes, UDP protocol).
Expected results:
Every open port will have an endpoint slice.
Additional info:
In order to resolve this issue, a service should be connected to the following ports: 9107 (worker and master nodes, TCP protocol), 10256 (worker and master nodes, TCP protocol), 6081 (worker and master nodes, UDP protocol). The endpoint slices should be created automatically once the service is up.
Please fill in the following template while reporting a bug and provide as much relevant information as possible. Doing so will give us the best chance to find a prompt resolution.

Affected Platforms:

Is it an

1. internal CI failure
2. customer issue / SD
3. internal RedHat testing failure

If it is an internal RedHat testing failure:

can be tested in any multi-node openshift cluster (sno clusters will only show gaps in 9107 and 10256 ports)

• Please share a kubeconfig or creds to a live cluster for the assignee to debug/troubleshoot along with reproducer steps (specially if it's a telco use case like ICNI, secondary bridges or BM+kubevirt).

If it is a CI failure:

• Did it happen in different CI lanes? If so please provide links to multiple failures with the same error instance
• Did it happen in both sdn and ovn jobs? If so please provide links to multiple failures with the same error instance
• Did it happen in other platforms (e.g. aws, azure, gcp, baremetal etc) ? If so please provide links to multiple failures with the same error instance
• When did the failure start happening? Please provide the UTC timestamp of the networking outage window from a sample failure run
• If it's a connectivity issue,
• What is the srcNode, srcIP and srcNamespace and srcPodName?
• What is the dstNode, dstIP and dstNamespace and dstPodName?
• What is the traffic path? (examples: pod2pod? pod2external?, pod2svc? pod2Node? etc)

If it is a customer / SD issue:

• Provide enough information in the bug description that Engineering doesn’t need to read the entire case history.
• Don’t presume that Engineering has access to Salesforce.
• Do presume that Engineering will access attachments through supportshell.
• Describe what each relevant attachment is intended to demonstrate (failed pods, log errors, OVS issues, etc).
• Referring to the attached must-gather, sosreport or other attachment, please provide the following details:
  • If the issue is in a customer namespace then provide a namespace inspect.
  • If it is a connectivity issue:
    • What is the srcNode, srcNamespace, srcPodName and srcPodIP?
    • What is the dstNode, dstNamespace, dstPodName and dstPodIP?
    • What is the traffic path? (examples: pod2pod? pod2external?, pod2svc? pod2Node? etc)
    • Please provide the UTC timestamp networking outage window from must-gather
    • Please provide tcpdump pcaps taken during the outage filtered based on the above provided src/dst IPs
  • If it is not a connectivity issue:
    • Describe the steps taken so far to analyze the logs from networking components (cluster-network-operator, OVNK, SDN, openvswitch, ovs-configure etc) and the actual component where the issue was seen based on the attached must-gather. Please attach snippets of relevant logs around the window when problem has happened if any.

• When showing the results from commands, include the entire command in the output.  
• For OCPBUGS in which the issue has been identified, label with “sbr-triaged”
• For OCPBUGS in which the issue has not been identified and needs Engineering help for root cause, label with “sbr-untriaged”
• Do not set the priority, that is owned by Engineering and will be set when the bug is evaluated
• Note: bugs that do not meet these minimum standards will be closed with label “SDN-Jira-template”
• For guidance on using this template please see
