This text discusses the installation and use of Rook Ceph as a replicated storage class for Kubernetes clusters. It provides step-by-step instructions on how to deploy Rook Ceph, create storage classes, deploy a file-sharing app, and test the resiliency of the storage solution. The article concludes by highlighting the scalability and reliability of Rook Ceph for Kubernetes storage needs.
Infinitely Scalable Storage for Kubernetes
Are you struggling with storage challenges in your Kubernetes cluster? Do you need a stable and reliable solution to ensure data replication and availability? Look no further than Rook Ceph, an easy-to-use replicated storage class for Kubernetes.
Choosing the Right Storage Solution
When it comes to storage in Kubernetes, native solutions often fall short in providing redundancy and distributed storage. That’s where Rook Ceph comes in. Here’s why it’s a great choice:
- It is a CNCF-graduated project, guaranteeing stability and quality.
- It is open source with excellent documentation and community support.
- It is easy to deploy and use.
- It offers fair performance.
Preparing Your Cluster
Before installing Rook Ceph, make sure you have a Kubernetes cluster with a minimum of 3 nodes and 1 empty attached disk for each node. You can use Scaleway Kapsule to easily create a Kubernetes cluster and attach the necessary disks.
Installing Rook Ceph
Follow these steps to install Rook Ceph:
- Clone the companion repo from GitHub.
- Clone the Rook repo and deploy the Rook Ceph operator.
- Create the Ceph cluster.
- Create the storage classes for RBD and CephFS.
- Deploy the Ceph dashboard for easy management.
Deploying an App
Once Rook Ceph is installed, you can deploy your applications with confidence. In this example, we deploy a self-hosted file-sharing app called psitransfer. Follow the steps to deploy the app and test the replication of data across disks.
When to Use Rook Ceph Block or Rook CephFS
If your applications require block storage with RWO access mode, use the Rook Ceph Block (RBD) storage class. If you need a shared file system with RWX access mode and POSIX compliance, use the Rook CephFS storage class.
Implementing Rook Ceph in your Kubernetes cluster can provide you with infinitely scalable storage and ensure data replication and availability. Don’t miss out on the benefits of this powerful solution.
