Everyone, Kubernetes is getting bigger and bigger. It has become the platform of choice to run microservices applications in containers, just like OpenStack did for and Cloud applications in virtual machines. When it comes to container storage there are three key aspects: * Providing persistent storage to containers, Ceph has drivers in Kuberntes already with kRBD and CephFS * Containerizing the storage itself, so efficiently running Ceph services in Containers. Currently, we have ceph-container (https://github.com/ceph/ceph-container) * Deploying the containerized storage in Kubernetes, we wrote ceph-helm charts (https://github.com/ceph/ceph-helm) The third piece although it's working great has a particular goal and doesn't aim to run Ceph just like any other applications in Kuberntes. We were also looking for a better abstraction/ease of use for end-users, multi-cluster support, operability, life-cycle management, centralized operations, to learn more you can read http://lists.ceph.com/pipermail/ceph-users-ceph.com/2017-October/021918.html. As a consequence, we decided to look at what the ecosystem had to offer. As a result, Rook came out, as a pleasant surprise. For those who are not familiar with Rook, please visit https://rook.io but in a nutshell, Rook is an open source orchestrator for distributed storage systems running in cloud-native environments. Under the hood, Rook is deploying, operating and managing Ceph life cycle in Kubernetes. Rook has a vibrant community and committed developers. Even if Rook is not perfect (yet), it has firm foundations, and we are planning on helping to make it better. We already opened issues for that and started doing work with Rook's core developers. We are looking at reconciling what is available today (rook/ceph-container/helm), reduce the overlap/duplication and all work together toward a single and common goal. With this collaboration, through Rook, we hope to make Ceph the de facto Open Source storage solution for Kubernetes. These are exciting times, so if you're a user, a developer, or merely curious, have a look at Rook and send us feedback!
