Clair Load Testing
This project provides a simple CLI for making requests to Clair. Although it doesn't boast the same HTTP control as a load testing tool such as wrk, it does offer a way to construct API calls to Clair that all container layers to be fetched without the need for Quay. This tool uses clairctl to create manifest definitions and requires it in your path.
NOTE:
clair-load-testis NOT for use on production instances of Clair.
Prerequisites
- A running instance of Clair (to test).
