Summary

In this chapter, we learned how to deploy a single-node Kubernetes cluster with Minikube. Then, we installed the Kubeless framework, Kubeless CLI, and Kubeless UI on top of our Minikube cluster. Once the Kubernetes cluster and Kubeless framework were ready, we created our first Kubeless function with Python and deployed it to Kubeless. Then, we discussed multiple ways of invoking Kubeless functions, namely with the Kubeless CLI, the Kubeless UI, HTTP triggers, scheduled triggers, and PubSub triggers. Next, we discussed how to debug common error scenarios that we encounter while deploying Kubeless functions. Then, we discussed how we can use the serverless framework to deploy a Kubeless function. Finally, in the activity, we learned how we can use a Kubeless function to send messages to a Slack channel.

In the next chapter, we shall introduce OpenWhisk, and cover OpenWhisk actions and triggers.
