Kubernetes is a powerful container orchestration tool that allows you to deploy and manage containerized applications, but it can sometimes take time to manage the underlying infrastructure. The serverless paradigm helps users deploy applications without having to worry about the underlying infrastructure. With the advent of Serverless 2.0, many platforms and tools now allow you to deploy serverless applications on Kubernetes.
Knative is a Kubernetes-based platform that provides components to deploy and manage serverless workloads. Knative offers open-source Kubernetes integration, cloud-agnosticism, building blocks, and extensibility. Tools like Red Hat’s Openshift also use Knative for users to deploy their serverless workloads on top of Kubernetes.
Knative features two main components: Eventing and Serving. Eventing manages events that trigger serverless workloads. Serving is a set of components to deploy and manage serverless workloads. Knative Serving enables developers to deploy and manage serverless applications on top of Kubernetes. With Knative Serving, developers can quickly and easily deploy new services, scale them up and down, and connect them to other services and event sources. This feature enables developers to build and deploy modern, cloud-native applications that are flexible, scalable, and easy to maintain.
In this tutorial, you will use Knative Serving to deploy a Node.js application as a serverless workload on a DigitalOcean Kubernetes cluster. You will use doctl (the DigitalOcean CLI) and kn (the Knative CLI) to create the Kubernetes cluster and deploy the application.
