We’re excited to announce kubriX 5.0.0 — a release focused on simplicity, resilience, and better day-2 operations. From a brand-new installer to streamlined observability and smarter pipelines, kubriX 5.0.0 is built to give platform engineers and developers a stronger foundation with less friction.

Here’s what’s new.

What’s New in kubriX 5.0?​

🚀 A Brand-New Installer​

Installing kubriX just got much easier. Instead of running local scripts on your workstation, you now simply run one kubectl apply command, and the kubriX-installer takes care of the rest — directly inside your Kubernetes cluster.

  • No more fragile workstation dependencies.

  • More stable, reproducible installations.

  • Faster setup for demos, PoCs, or production clusters.

⚡ Smarter Bootstrapping​

Bootstrapping kubriX (or kubriX-prime) in your GitOps repo is now part of the installer:

  • Set KUBRIX_BOOTSTRAP=true and provide your DNS provider, domain, and Git repo — and you’re ready in minutes.

  • Out-of-the-box support for AWS, Cloudflare, STACKIT, and IONOS (plus any provider supported by external-dns).

  • Works seamlessly on local Kind clusters for quickstarts or on your real production cluster.

🔒 Stronger Defaults & Security​

  • All platform services now dynamically generate admin usernames and passwords — even if you don’t customize them, no one can guess the defaults.

  • Secrets handling and password rotation are documented with clear guides.

  • Default Velero backup schedules for critical Kubernetes resources are included, so you always have a safety net.

📊 Better Observability & Alerting​

  • False-positive/negative alerts reduced, and alerting secrets are no longer mandatory for teams that don’t need them.

  • Matrix chat integration added as an Alertmanager receiver — a decentralized, open-source alternative to Slack.

  • Mimir cardinality dashboard integrated, so you can track metric series growth and find bottlenecks.

  • Loki topology switch: from SingleBinary to SimpleScalable, making logs more performant for both small and very large clusters.

🔧 Dependency & Service Improvements​

  • Switched from the Bitnami Keycloak chart to the official Keycloak Operator - future-proof and open-source-friendly.

  • Smarter dependency detection shows which helm chart dependencies and container images would really be used.

  • Key platform updates:

    • Kargo 1.7 (with a new openPr flag for approval workflows in pipelines)

    • k8s-monitoring v3 (many improvements, new features, stability)

    • external-secrets v0.17

    • Argo CD v3.1.6

  • Nearly every other platform service has been refreshed for stability and security.

🧪 Testing & Reliability​

  • Early integration of Testkube for end-to-end platform testing. We already use it internally, and plan to expand it so you can validate custom platform behaviors in every release.

  • Installer hardened with countless under-the-hood improvements to make it battle-ready for real-world environments.

📚 Documentation Upgrades​

  • Full restructure of the documentation, with more details on GRC (Governance, Risk, and Compliance).

  • Expanded guides for secrets management, password rotation, and cluster operations.

  • A stronger knowledge base for platform engineers and developers, updated continuously.

Why kubriX 5.0.0 Matters​

  • Faster, safer installations — the installer is cluster-native and resilient.

  • Stronger defaults — no weak passwords, built-in backups, and improved alerting.

  • More observability — dashboards, alerts, and logging at scale are just there.

  • Future-proof upgrades — by aligning with official operators and the latest upstreams.

  • Better knowledge base — documentation that empowers platform engineers, not slows them down.

With kubriX 5.0.0, setting up and running an internal developer platform is simpler, more secure, and more scalable than ever.
