@Public @Unstable public class Resource extends BaseResource implements Cloneable
Resource determines the amount of resources (vcores, memory, network, etc.) usable by a container. This field determines the resource to be applied for all the containers of a component or service. The resource specified at the service (or global) level can be overriden at the component level. Only one of profile OR cpu & memory are expected. It raises a validation exception otherwise.
