Summary

This chapter discussed OpenFaaS, its architecture, and how we can use it as a serverless framework to deploy functions in Docker Swarm. OpenFaaS has several compelling features, especially its ease of use. This chapter showed that deploying an OpenFaaS stack is quite simple in Docker Swarm infrastructure. Then, this chapter continued to discuss how to define, build, pack, and deploy functions in OpenFaaS. It also discussed an advanced topic of how to tweak and prepare custom templates.

Monitoring OpenFaaS is quite simple, as it comes with Prometheus built in. We only need to install a Grafana dashboard and connect it to the Prometheus data source and we will have a ready-to-use dashboard, helping us to operate an OpenFaaS cluster.

The next chapter will introduce the Fn Project, which allows us to deploy an FaaS platform on a plain Docker infrastructure.
