Network Policy is an API that helps Kubernetes users secure their networking. If you have ever created more than 1000 Network Policies, you have probably asked (yourself or your cluster provider): am I hitting the limit? How many more can I create? Without well-defined scalability limits almost any bug may be a scalability bug. We will discuss why Network Policies are so difficult to scale test and present the Network Policy-focused scale testing framework we developed. We will also share some tools to translate end users’ requirements to testing profiles. Every platform or network plugin may have different requirements for a successful scale test, we will share testing experience and results for ovn-kubernetes and Calico network plugins as first framework users. Attendees will learn how to use our scale testing framework, contribute more performance profiles based on your needs, or just get an idea on how to better explain scale limits to end users.
