CobaltCore

CobaltCore is an opinionated OpenStack distribution built on IronCore’s foundation to run non-cloud-native workloads, with KVM hypervisor operators, workload placement and scheduling (cortex), a self-service portal and Ceph storage, managed through Kubernetes. It is software; its contracts are the Kubernetes resources its operators define. Apache 2.0.

CobaltCore carries OpenStack — and the virtual machines that still run most enterprise workloads — into a Kubernetes-operated stack. It is part of NeoNephos, a Linux Foundation Europe project.

  • Built on OpenStack and KVM - Nix packages and modules for OpenStack, a hypervisor operator and a KVM node agent.
  • Scheduling as resources - cortex defines cortex.cloud resources — decisions, pipelines, knowledges, KPIs — for placement and scheduling.
  • No single repository - The project spans several repositories under cobaltcore-dev.
