Constellation – An always encrypted Kubernetes engine
Hey HN, my colleagues and I have been working on Constellation for 1.5+ years. We open sourced it today under AGPLv3. It's a standalone Kubernetes engine/distribution that operations-wise is very much vanilla K8s (v1.24). Security-wise, it comes with some new concepts: It's designed to shield K8s clusters as a whole from the cloud. The goal is that not even the cloud provider and its employees can access any data in a cluster. Constellation basically ensures that all nodes in a cluster (1) run inside verified "Confidential VMs" and (2) encrypt all network traffic and storage.…

In plain words
Constellation is a Kubernetes distribution designed to protect entire clusters from cloud provider access. It runs on confidential virtual machines with encrypted memory and encrypts all network traffic and storage, ensuring data remains private even from cloud infrastructure administrators. The platform operates as standard Kubernetes operationally while adding security layers through hardware-based isolation and encryption. It is intended for organizations requiring strong data privacy guarantees in cloud environments.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
