* Creating infrastructure MachineSets
[ https://docs.openshift.com/container-platform/4.1/machine_management/creating-infrastructure-machinesets.html ]
Section Number and Name:
Describe the issue:
This section describing about adding Infrastructure node, but the target environment is only AWS.
v4.1 does not only support AWS IPI, but bare metal UPI, vSphere UPI, AWS UPI are also suppored.
Suggestions for improvement:
Add same section with IPI for AWS for bare metal UPI, at least, we should provide configuration steps and explanation about how to configure infrastructure node in UPI. It's important for CU's subscription counting.
User is usually considering to add infra node for logging, monitoring, ingress router components due to not counting as paid subscriptions.
My customer met this issue in OCP4.3 and it will be same issue in OCP4.4 either, so I open again with changing the version as 4.4.
This is not for 4.1 specific issue. This is about 4.x issue so we need this information with latest version
My customer also met this issue in OCP4.4
We referred this way which is mentioned in a mail-thread to configure separated infra-node and I'm not sure this guidance can be delivered to the customer officially.
The customer wants official guidance to configure adding Infrastructure node on bare metal UPI.
I have attached another case for the same issue. This time the customer found and followed the KCS articles themselves, but they do not work as the cluster still only recognises the nodes as either master or worker. No infra nodes are found when checking OCM which meand the customer is still paying subscriptions on thesee nodes.
Using infrastructure nodes is a supported feature to reduce subscription costs, but there is no official product documentation on how to implement this feature for UPI clusters.
Please add documentation to support this feature.
Hello Cody Hoag,
Thank you so much for your time and efforts on product documents.
As we seen it, we have done this already on the PR; https://github.com/openshift/openshift-docs/pull/24450 ,would we publish it on this BZ accordingly?
Our partner NEC is waiting on this for a while and they would like to know the most current status.
Would you please share it with us ?
I am grateful for your help and clarification.
@Jianwei would creating an infra node for bare metal UPI just follow the combination of these existing articles?
1. Create a worker machine following this .
2. Add infra label to make it an infra node following this .
There are currently docs to complement the worker/infra node labeling discussion in progress, which can also be referred to when they're finished. 
@Gaoyun Do you know the answers to my questions asked in comment#16? Or can you assign this to the appropriate person who could answer this? Thanks!

Yes, I think this works for bare metal UPI scenario.
