Project mention: Show HN: Proxmox VE Helper Scripts: Make managing your Proxmox homelab a breeze | news.ycombinator.com | 2024-11-12
If you want to manage VMs, then you're probably using terraform + provider. However, SDN (Software Defined Networking) is not yet supported [1], which makes any kind of deployment with network separation not feasible (using IAC only).

mantis
Mantis is a unified infrastructure as code framework that replaces Terraform and Helm (by augur-ai)
Project mention: Mantis: Cue based alternative for Terraform and Helm | news.ycombinator.com | 2024-10-27Three days. 72 sleepless hours. A corrupted MongoDB instance with a simple configuration error. Millions of dollars at stake. That’s what broke me.
My team was responsible for deployment of over 30 microservices across multiple clouds, directly in our enterprise on-prem customers’ environments. We thought we had it under control. We were SO wrong!.
The reality hit hard: Hour-long deployments stretched into months. Security reviews became endless loops. Integration issues multiplied exponentially. Key stakeholders vanished when we needed them most.
But that production incident with our important fintech client? That was different. As I watched my team burn out during those three days of firefighting, due to a misconfigured database, I realized something had to change.
Here’s the hard truth: The cloud was supposed to simplify things. Kubernetes was meant to make microservice management easier. Instead, we got more complexity, more toil, and more sleepless nights.
I’ve seen this pattern destroy teams across companies. I’ve watched brilliant engineers, engineering leaders and CISOs crumble under the weight of infrastructure chaos. — That’s why I built Mantis.
It’s not just another tool — it’s a complete reimagining of infrastructure configuration. One unified AI-powered engine replacing both Terraform and Helm. Modular configurations that actually work. Built-in validations that prevent disasters before they happen.
