 # IBM Toolchain Lab

 By following this tutorial, you create an open toolchain that includes a Tekton-based delivery pipeline. You then use the toolchain and DevOps practices to develop a simple "Hello World" web application (app) that you deploy to the IBM Cloud Kubernetes Service. 
 
 [Tekton](https://www.ibm.com/cloud/blog/tekton-a-modern-approach-to-continuous-delivery") is an open source, vendor-neutral, Kubernetes-native framework that you can use to build, test, and deploy apps to [Kubernetes](https://www.ibm.com/cloud/learn/kubernetes). Tekton provides a set of shared components for building [continuous integration](https://www.ibm.com/cloud/learn/continuous-integration) and [continuous delivery](https://www.ibm.com/cloud/learn/continuous-delivery) (CICD) systems. As an open source project, Tekton is managed by the [Continuous Delivery Foundation](https://cd.foundation) (CDF). The goal is to modernize continuous delivery by providing industry specifications for pipelines, workflows, and other building blocks. With Tekton, you can build, test, and deploy across cloud providers or on-premises systems by abstracting the underlying implementation details. Tekton pipelines are built in to [ IBM Cloud™ Continuous Delivery.](https://www.ibm.com/cloud/blog/announcements/build-and-deliver-using-tekton-enabled-pipelines).
