Open source Pelagia makes storage clusters at scale easier to operate

Mirantis, the Kubernetes-native AI infrastructure company enabling enterprises to build and operate scalable, secure, and sovereign AI infrastructure across any environment, today announced the release of Pelagia, an open source Kubernetes controller for lifecycle management of Ceph software-defined storage.

Pelagia complements Rook, a CNCF-hosted open source project, adding lifecycle automation that streamlines operations for large and high-traffic deployments.

"Pelagia reflects experience gained from years of managing Ceph in production at scale," said Shaun O'Meara, CTO, Mirantis. "It works alongside Rook to add needed lifecycle automation and a simplified control plane for large-scale environments, whether built on bare metal or virtual machines."

Pelagia comes from the Mirantis OpenStack for Kubernetes (MOSK) product, which for more than five years, was used to deploy and manage large production Ceph clusters where reliability was critical. Mirantis is releasing Pelagia as open source software, making it widely available to anyone.

Pelagia simplifies operations, improves operator transparency into cluster status, and fits into GitOps workflows. Pelagia standardizes how Ceph is operated across Kubernetes clusters.

Pelagia continues to serve as the storage lifecycle layer for Mirantis’ broader infrastructure strategy, including the open source Rockoon controller for OpenStack and the modular k0rdent platform for Kubernetes-native clouds.

“Most OpenStack deployments leverage the integration of OpenStack, Kubernetes and Ceph, with tens of millions of cores globally implementing that open infrastructure blueprint,” said Thierry Carrez, general manager of the OpenInfra Foundation. “Mirantis opening up Pelagia to the community tracks with the company's longstanding commitment to those open source infrastructure projects, crystalizing Mirantis operational best practices and experience into software that can be leveraged by all OpenStack and Kubernetes deployers.”

A longtime proponent of open source, Mirantis is actively involved and contributes to more than 50 open source projects with efforts that are steered by the company’s Open Source Program Office directed by Randy Bias. Pelagia plays a central role in k0rdent’s virtualization support, enabling consistent and predictable lifecycle management of Ceph-backed persistent volumes and data volumes for KubeVirt-based VMs. Mirantis plans to add Pelagia to the k0rdent catalog with opinionated defaults and tested integrations.

Pelagia is available now under an open source license. Quick start instructions are available at https://mirantis.github.io/pelagia/quick-start/installation. For more information, join the user community discussion group on GitHub.
