Package-based platform architecture using OCI artifacts — OpenStack for the Kubernetes era with CNCF backing.

Strengths

•FluxCD-based package system treats platform components like apt packages with OCI artifact distribution.
•BYOP model lets users pick and install only needed Packages via cluster-scoped CRDs.
•Replaced bash scripts with proper operators — two CRDs (Package, PackageSource) handle all platform logic.

Weaknesses

•Enterprise bare-metal cloud is well-funded space with OpenStack, Rancher, and Talos already established.
•v1.0 rename from 0.42 suggests architectural debt from earlier versions still being worked through.

Post Description

Hi HN — we’ve released Cozystack v1.0, the first stable release of our open-source cloud platform (it's a CNCF Sandbox Project).

We built it for a simple use case: when you want the convenience of cloud services, but you want them on your own hardware, under your own control, with your own economics.

Cozystack turns bare metal into a cloud platform that can provide VMs, managed Kubernetes, databases, load balancers, GPU as a Service and other services through a unified platform model. It’s especially relevant for hosting providers, regulated companies like banks, and startups that are tired of building around public cloud costs and lock-in.

v1.0 is a big release for us: we reworked core platform packaging and operations around the v1 model, documented the v0.41 → v1.0 upgrade path, and made the ready-to-use platform flow much more explicit. The current docs position v1 as the stable branch and include provider-oriented variants like isp-full.

If you’re trying to build your own cloud instead of renting one forever, I’d love your feedback.
