How to Deploy Your First App with Harness CD in 15 Minutes
Harness, Thursday, October 8th, 2026
Harness tutorial shows how to set up a rolling Kubernetes deployment with rollback using Harness CD.
This walkthrough shows developers new to Harness CD how to build, configure and execute a rolling deployment of a sample application to Kubernetes via a Harness Delegate.
It contrasts ad hoc deploy scripts and SSH-based releases with a reusable setup that separates what is deployed, where and how, so promoting from dev to prod becomes a settings change.
The tutorial deliberately deploys a broken build to demonstrate one-click rollback and deployment history, and requires an SCM account, Docker Hub, a Kubernetes cluster and a Harness account.
