Marketing speak aside, Rook is an open-source version of AWS EBS and S3, which you can install on your own clusters. To do this we introduce two new API resources: PersistentVolume and PersistentVolumeClaim.A PersistentVolume (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes. High availability implemented through kubernetes using replication=1 and … Awesome. We invited Pete Brey, Sr. First and foremost, it’s, it allows you to set up a shared storage platform between multiple different Kubernetes cluster. After setting up the Ceph cluster, we would consume it with Kubernetes. You may be familiar with Red Hat, Ceph Storage, and Ceph is famous for being able to scale massively to support demanding data requirements. In this guide, you will use Rook to setup Ceph storage within a Kubernetes cluster. One is that can you talk about the roadmap? Centrally, Ceph allows you to consume storage in different interfaces, as objects, block or file. There are several supported storage back-end, such as: AzureDisk, AWSElasticBlockStore, GCEPersistentDisk, Ceph, NFS, etc. Ways to provide both long-term and temporary storage to Pods in your cluster. Kubernetes has native support for Ceph storage in the form of official plugins. Introduction A StorageClass provides a way for administrators to describe the "classes" of storage they offer. This client is not in the official kube-controller-manager container so let’s try to create the external storage plugin for Ceph. Note: CephFS support in Kubernetes requires at least Ubuntu 18.04LTS and OpenStack Train. Copy ceph.repo in /etc/yum.repos.d/ and download ceph-common. I’m also curious how much AI and ml you are using for this platform itself. Rook is such an operator, which reacts to Kubernetes custom objects. And so we really feel that this is a new watermark within the industry, for object storage platforms. The Ceph project has a long history as you can see in the timeline below. This guide will walk you through the basic setup of a Ceph cluster and enable you to consume block, object, and file storage from other pods running in your cluster. Easily accessible storage that can quickly scale up or down. Pete Brey: That’s a great question. Swapnil Bhartiya  You’re talking about some applications are going to require, which is also like data versus application, you know, these are two different worlds, you know, because once you build data lake, or you have, you have to also kind of ensure that the the future workloads are fully taken care off. That is a big challenge. I am assuming that your Kubernetes cluster is up and running. Where do these applications store data to make it highly available? Creating object storage services using public cloud infrastructure that is cost-competitive with services of public clouds is challenging. Ceph Persistent Storage for Kubernetes with Cephfs. Both Ceph RBD images and CephFS file systems can be leveraged to provide Kubernetes persistent volumes.For in-depth coverage of integrating Kubernetes with Charmed Ceph see the Charmed Kubernetes … I switched the kube-controller-manager docker image with an image provided by AT&T which includes the ceph-common package. 5: Ceph RBD pool.
