I have found that there are two sections that have the exact same content in the OpenShift documentation that is published on access.redhat.com.
 
I am attaching a couple of screenshots and the output of the diff command that says that the only difference is the numbering of the section headings.
 
Chapter 2. Working with pods

• Section: 2.3. Configuring an OpenShift Container Platform cluster for pods
• URL: https://access.redhat.com/documentation/en-us/openshift_container_platform/4.12/html-single/nodes/index#nodes-pods-configuring
   
  
   
  Chapter 8. Working with clusters
• Section: 8.3. Configuring an OpenShift Container Platform cluster for pods
• URL: https://access.redhat.com/documentation/en-us/openshift_container_platform/4.12/html-single/nodes/index#nodes-cluster-pods-configuring
   
  

 
I suppose this content duplication is an error and I would like to know which is the correct URL to reference in my lecture content:
 

Chapter 2. Working with pods * Section: 2.3. Configuring an OpenShift Container Platform cluster for pods

• URL: https://access.redhat.com/documentation/en-us/openshift_container_platform/4.12/html-single/nodes/index#nodes-pods-configuring

Chapter 8. Working with clusters * Section: 8.3. Configuring an OpenShift Container Platform cluster for pods

• URL: https://access.redhat.com/documentation/en-us/openshift_container_platform/4.12/html-single/nodes/index#nodes-cluster-pods-configuring
