Although it's not the best-performing solution, NFS is still used with cloud-native applications where multi-node write access is required. In this section, we will create an NFS-based persistent storage for this type of application. You will learn how to use OpenEBS and Rook to ReadWriteMany (RWX) accessible persistent volumes for stateful workloads that require shared storage on Kubernetes.
Getting ready
For this recipe, we need to have either rook or openebs installed as an orchestrator. Make sure that you have a Kubernetes cluster ready and kubectl configured to manage the cluster resources.
How to do it…
There are two popular alternatives when it comes to providing an NFS service. This section is sub-divided further into the following subsections to explain the process using Rook and OpenEBS:
- Installing NFS prerequisites
- Installing an NFS provider using a Rook NFS operator
- Using a Rook NFS operator storage class to create...
