Kubernetes Container

This page describes the Optimization Pack for the Kubernetes Container component type.

Metrics

Constraints

The following tables show a list of constraints that may be required in the definition of the study, depending on the tuned parameters:

Formula	Notes
component_name.cpu_request <= component_name.cpu_limit
