OPENSHIFT NETWORKING FROM A CONTAINER/WORKLOAD POINT OF VIEW – PART 4: CONTAINER NETWORKING USING OPENSHIFT/KUBERNETES SERVICES

To allow stable endpoints in an environment of ever changing starting and stopping Pods (and therefore constantly changing IP addresses), Kubernetes introduces (and OpenShift uses) the concept of services.

However OpenShift SDN also allows pods on different nodes to communicate with each other. To this end, […]
