An ephemeral preview environment is an isolated, temporary Kubernetes deployment created from a single feature branch and torn down when the work is done. Every branch gets its own namespace, its own image, its own URL - and zero of it lingers afterward. Ephemeral environments on Kubernetes make this pattern available on your own cluster - but a hands-on, open-source, portal-native version - feature branch to isolated namespace to one-click destroy, backed by real Tekton CI and Argo CD GitOps - is conspicuously missing from the public record.

So I built one, end to end, on the same local try-kuberocketci testbed from my last post: a kind cluster running KubeRocketCI 3.13.5 with Tekton, Argo CD, and self-hosted GitLab. This post is the full walkthrough - every screenshot, every line of terminal output, captured from a live run. We will take a stable main deployment, branch off it, ship a change that is visible only in the preview environment, inject per-environment config through GitOps, prove the two environments never touch each other, and then destroy the whole thing - leaving the baseline exactly as it was.
