GitLab CI integration in KubeRocketCI lets a single application run its CI pipeline in GitLab CI - on a GitLab Runner - instead of Tekton, while still being managed as a first-class Codebase on the platform. You set one field on the Codebase (spec.ciTool: gitlab), and KubeRocketCI generates a .gitlab-ci.yml in the repository; GitLab then runs the pipeline, with no Tekton involved. From then on, every merge request runs a review pipeline and every merge runs a build pipeline - all native GitLab CI, all on your own cluster.

This is part three of my hands-on series on the local try-kuberocketci testbed. In part one I stood up the full platform in two commands; in part two I built ephemeral preview environments from a feature branch. Both ran their CI in Tekton. This post takes the same kind cluster running KubeRocketCI 3.13 and shows the multi-CI path: how GitLab CI integration works, the three things you must set up before you enable it - a Runner, the onboarded CI/CD components, and a ConfigMap - and a full review-to-build run with real output.

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.

Evaluating an internal developer platform without a working instance is like buying a car from a brochure. Every KubeRocketCI install path in the official docs assumes a cluster you already have - AWS EKS, GKE, an on-prem control plane. Today I ran the try-kuberocketci testbed end-to-end on my Apple Silicon Mac using Docker Desktop and two commands: make testbed (approximately 18–20 minutes) and make e2e (approximately 12 minutes). The result is a fully wired KubeRocketCI local install - Tekton, Argo CD, SonarQube, self-hosted GitLab CE, Prometheus, Grafana, Tekton Results, and the Portal - running in a disposable kind cluster. No cloud account. No /etc/hosts edits. No clicking through UIs to trigger pipelines. This post walks through exactly what happened, command by command, screenshot by screenshot.

Building CI/CD on Kubernetes used to mean running Jenkins or GitLab CI in a pod and calling it done. Tekton changed that by making pipelines first-class Kubernetes objects - Tasks and Pipelines are CRDs, PipelineRuns are namespaced resources, and every step log is a container log. KubeRocketCI goes a step further: it ships a complete, production-grade CI/CD platform on top of Tekton so your team gets sensible defaults, a portal UI, GitOps-managed pipeline definitions, and opinionated quality gates - without the months of plumbing work that comes with assembling those pieces from scratch. I've seen teams go from a bare cluster to a working build-deploy loop in under a day using this stack.

In modern cloud environments, secure and efficient access management is essential, especially for platforms like Amazon EKS. This blog will guide you through integrating OpenID Connect (OIDC) authentication using Microsoft Entra, making it easier to manage access to your EKS clusters and KubeRocketCI Portal. By implementing this approach, you can simplify user authentication while ensuring strong security controls. Whether you're improving compliance or streamlining access for your team, this integration is a practical solution to enhance your cloud-native workflows.
