faas/sample-functions/hey

Overview

hey is a HTTP load generator..

This is a OpenFaaS Dockerfile function, it wraps hey.

Use it to test your functions!

For example, generate load and watch them scale up and down!!!

Demo

From the OpenFaas Portal:

1. Deploy the nodeinfo function
2. Deploy this hey function
3. Use hey to load test nodeinfo with a request body like this:

-m POST -d '{}' http://127.0.0.1:8080/function/nodeinfo.openfaas-fn

Tips

• hey does not randomize the request payload
• hey defaults Content-Type to "text/html"
• hey requires parameters to be in a certain order
  • For example, if you don't use the order above, the post body may be empty.
