Difficulty: Introduction
Estimated Time: 20 minutes

Nuclio is an open source serverless platform which allows developers to focus on building and running auto-scaling applications without worrying about managing servers.

  • The fastest platform running up to 400,000 function invocations per second
  • Enables simple debugging, regression and a multi-versioned CI/CD pipeline
  • Supports a variety of open or cloud-specific event and data sources with common APIs
  • Is portable across low-power devices, laptops, on-premises and multi-cloud deployments

You will learn how:

  • to install Nuclio on Kubernetes
  • functions are deployed and removed
  • functions are named, exposed, and invoked
  • functions are listed, inspected and monitored

More about the Nuclio architecture is described in the Nuclio documentation.

Nuclio is a new serverless project, derived from Iguazio's elastic data life-cycle management service for high-performance events and data processing. One of the many emerging serverless solutions for Kubernetes.

Step 1 of 6

Your Kubernetes Cluster

For this scenario, Katacoda has just started a fresh Kubernetes cluster for you. Verify it's ready for your use.

kubectl version --short && \ kubectl get componentstatus && \ kubectl get nodes && \ kubectl cluster-info

The Helm package manager used for installing applications on Kubernetes is also available.

helm version --short

Kubernetes Dashboard

You can administer your cluster with the kubectl CLI tool or use the visual Kubernetes Dashboard. Use this script to access the protected Dashboard.
