I've had a few calls with users recently who are moving from AWS Lambda to bare Kubernetes, and struggling to get this kind of working scaling right for them. So we sat down and put together an example to show how it could be done.<p>Why is this Show HN? It's a code example, it's something we wrote that didn't exist before in this way and you can run it and try it out. We also added a detailed write-up that we're posting here.<p>Disclaimer: we both work at OpenFaaS Ltd and maintain the OSS project full time.
