In a typical theoretical system, I would call the different applications that make up the system nodes. However this is confusing in a Kubernetes cluster system for two reasons:

1. "Node.js" is often shortened to "node", and not all of the nodes in my system are "Node.js" processes.
2. Kubernetes uses the word "node" to refer to physical components in the cluster.

So the question is, what terminology is used to describe the subject that you would run on a pod? Are they projects? Processes? Application nodes? Applications?

None of the above sound right to me.

CodePudding user response：

Pods contain one (or rarer more) application(s):

A Pod models an application-specific "logical host": it contains one or more application containers which are relatively tightly coupled.

In the Kubernetes universe, Nodes are the physical or virtual machines that your cluster is running on. Pods run on the Nodes. I suggest to avoid the term Node for applications.

Usually it would be a "service" (although it clashes with k8s service) or a "microservice"
