Almost all diagrams illustrating service solutions on platforms like Kubernetes/OpenShift are not standardized in any way. As there is not much reference material available for UML modeling I would like to ask how to model such a solution.
Note: The question has been closed with reference to this question. The referenced question addresses Docker containers. However, it does not answer (and it doesn't even ask!) how pods (holding such containers) and services (exposing endpoints to the outside of a cloud platform) as well as their multiplicity and nesting in a deployment diagram can be represented.
Consider the following example (I know that this sequence of two services might have limited practical relevance, but for the sake of simplicity consider it a composite service or something..)
Assuming that I would like to
- deploy this OrderService to an OpenShift cluster
- deploy the sub services in separate containers
- have the containers in a scalable number of pods
- provide an endpoint using an OpenShift service
does the diagram below make any sense? Is there a better way to distinguish between the OrderService endpoint and the service rendered as a pod? What would you improve?
