Above at Database – PostgreSQ L we talked about Kubernetes operators. Challenges with Ceph + Kubernetes. So to answer the first question in terms of, you know, taking a peek at the direction we’re headed, it’s really about servicing the data needs of organizations. I am assuming that your Kubernetes cluster is up and running. … Kubernetes has native support for Ceph storage in the form of official plugins. This provides a more streamlined experience for administering your Ceph cluster by hiding Ceph components like placement groups and storage maps while still providing the options of advanced configurations. And so you talk about data lakes, and absolutely, they’re very important force within the industry. The Ceph provider for Rook is stable and production ready. The Ceph project has a long history as you can see in the timeline below. I’m also curious how much AI and ml you are using for this platform itself. And so with this announcement with external mode, we’re able to support an external Red Hat Ceph Storage cluster, that will support block file and object storage. And we know from experience, that most applications are going to require some level of persistence and some level of data. Figure 29. If you check the status, you should see something like: Here notice that my Ceph monitors IPs are 10.0.1.118, 10.0.1.227 and 10.0.1.172. To talk about this release, we have with us today. K8s Integration. Made with WordPress & Open Source, Dirk & Swap: Conversations on Open Source, Days Of Building A Business Around CI/CD Are Numbered : 2021 Predictions By Vendia, You Can’t Secure What You Can’t See: 2021 Predictions By Lacework, Kubernetes Will Be At the Center of Hybrid Cloud Story: 2021 Predictions By Robin.io, DevOps Will Retire In Favor of SREs: 2021 Predictions By DataStax, AI Will Be Developers’ Best Friend: 2021 Predictions By Peritus, Everything You Need To Know About SolarWinds Attack, Under Investment In Software Development Will Hurt Companies: 2021 Predictions By Camunda, Cisco To Acquire Software Startup Dashbase, Geoverse To Launch 5G-Enabled GeoCore By Mid-2021, Google Announces New Cloud Regions In Chile, Germany, Saudi Arabia, More Cloud Foundry Than Ever: 2021 Predictions By anynines, Rise Of GitOps, Disappearance Of Kubernetes: 2021 Predictions By Codefresh. So we provide a lot of flexibility with the multi cloud gateway. Once the CephFS provider is up, try creating the persistent volume claim. And we have customers who have used Seth for some of their most mission critical customer support applications where they’ve scaled into the hundred petabyte range. It is a battle-tested software defined storage (SDS) solution that has been available as a storage backend for OpenStack and Kubernetes for quite some time. This post was originally published on Velotio Blog. There are good storage solutions like Gluster, Swift but we are going with Ceph for following reasons: We are going to use 2 types of storage in this blog to integrate with Kubernetes. There are a number of approaches that could possibly work. CephFS. This will set necessary CEPH configuration for the helm chart (e.g. You know, years ago, we had been telling people about digital transformation move to the cloud, suddenly, you know, everybody, it has become a kind of urgency. Product Marketing Manager at Red Hat to deep dive into this release. So we’re bringing the massive scalability story to Kubernetes environments. CEPH persistent storage backend for Kubernetes ... A new service, ‘rbd-provisioner’, will be added to CEPH storage backend. Pete Brey: OpenShift Container Storage provides persistent storage services for Kubernetes applications. Pete Brey: So it’s very interesting because Open Data hub started out as an internal redhead project to support our own needs to support Our customers, literally our support centers who are taking phone calls from our customers. I wrote about Rook storage a few weeks ago, but maybe you already have Ceph cluster running in your datacenter. Along with the utilization of storage systems like Ceph, Rook eliminates Kubernetes storage challenges like dependency on local storage, cloud providers vendor lock-in and day-2 operations within the infrastructure. And you might ask, Well, what benefits or advantages does that really buy me? This document describes the concept of a StorageClass in Kubernetes. Damit du Speicher dynamisch zur Verfügung stellen kannst arbeitet Kubernetes mit Storage Classes. All of these components are running in your Rook cluster and will directly interact with the Rook agents. Ceph stripes block device images as objects across the cluster, which means that large Ceph Block Device images have better performance than a standalone server! Rook enables Ceph to run in Kubernetes, just as other software which keeps persistent files, e.g. Default is rbd, but that value is not recommended. Note: CephFS support in Kubernetes requires at least Ubuntu 18.04LTS and OpenStack Train.
