The runtime_constraints of a ContainerRequest must include a ram field. ram is a number of bytes, so it must be a positive integer. The API server must validate this on every create and update of a ContainerRequest when its state is Committed. If a request tries to set ram to an unacceptable value, the server must reject the request with HTTP error code 422, and the response JSON should include an error message close to "runtime_constraints ram must be a positive integer."
