Going back to the end of the previous sub-chapter, we introduce the Rook storage provider. It is inserted between the hard disk of the VMs, always based on NFS, and the Kubernetes cluster. As said previously, NFS allows remote hosts to mount filesystems over a network and interact with those filesystems as though they are mounted locally. This enables system administrators to consolidate resources onto centralized servers on the network. As a prerequisite, NFS client packages must be installed on all nodes (nfs-utils on CentOS), where Kubernetes might run pods with NFS mounted. However, the official guide can be found here.
First deploy the Rook NFS operator using the following commands
# Clone the repository and change directory git clone --single-branch --branch v1.5.3 https://github.com/rook/rook.git cd rook/cluster/examples/kubernetes/nfs # Then launch kubectl create -f common.yaml -f operator.yaml # Check if the operator is up and running $ kubectl get pod -n rook-nfs-system NAME READY STATUS RESTARTS AGE rook-nfs-operator-f79889845-8r5kq 1/1 Running 0 11m |
