Kubernetes NFS Persistent Volume: How to Configure

Let's examine the configuration of the Kubernetes NFS persistent volume. We will provide you with a thorough breakdown of the entire setup procedure with the help of our Server management support services at skynats.

The widely used container orchestration platform Kubernetes is used to deploy and manage containerized applications. Persistent storage for containerized applications can be provided using persistent volumes (PVs), which is one of Kubernetes' key features. NFS (Network File System) PVs are just one of the many types of PVs that Kubernetes supports. We will go over how to configure a Kubernetes NFS Persistent Volume in this article.

Step 1: Configure an NFS server

Setting up an NFS server is the first step in configuring an NFS persistent volume. Either a new NFS server can be installed or an existing one can be used. You can use a Linux machine and install the required software packages, including the NFS server software, if you're setting up a new NFS server. You must configure the NFS server with the proper permissions and access controls after it has been set up. Make sure that the NFS server and the shared directories can only be accessed by approved systems and users.

Step 2: Create an NFS share

The next step is to create an NFS share on the server. To create an NFS share, you need to create a directory on the NFS server and share it using the NFS protocol. Configure the share with appropriate permissions and access controls. You can use the exportfs command to export the directory as an NFS share. For example, to export a directory named /data as an NFS share, you can use the following command:

sudo exportfs -o rw,sync,no_subtree_check,no_root_squash /data

In this command, the options - o rw,sync,no_subtree_check,no_root_squash determine the NFS export options. These options allow read and compose admittance to the offer, guarantee that information is synced between the client and server, incapacitate subtree checking, and allow root admittance to the offer.

Step 3: Define a Persistent Volume (PV)

When the NFS share is set up, you really want to characterize a Persistent Volume (PV) in Kubernetes that references the NFS share. To characterize a PV, you really want to make a YAML record that determines the NFS server's IP address, the way to the NFS share, and some other required boundaries, for example, the capacity size and access mode.

Here is a model PV YAML document:

apiVersion: v1

kind: PersistentVolume

metadata:

  name: nfs-pv

spec:

  capacity:

    storage: 10Gi

  accessModes:

    - ReadWriteMany

  nfs:

    server: 192.168.1.100

    path: /data

In this model, the YAML document characterizes a PV named nfs-pv with a capacity limit of 10GB. The accessModes field determines that the PV can be gotten to in peruse compose mode by various units all the while. The nfs field indicates the NFS server's IP address (192.168.1.100) and the way to the NFS share (/data).

Step 4: Apply the PV YAML file

After defining the PV YAML file, you want to apply it to Kubernetes utilizing the kubectl apply - f command. For instance, if you saved the YAML file as nfs-pv.yaml, you can apply it utilizing the following command:

kubectl apply -f nfs-pv.yaml

In Kubernetes, the PV is created using this command.

Step 5: Create a Persistent Volume Claim

The following stage is to make a Persistent Volume Claim (PVC) that demands capacity from the NFS PV. To make a PVC, you really want to make another YAML record that indicates the ideal stockpiling size and access mode for the PVC.

Here is a model PVC YAML document:

apiVersion: v1 

kind:

Conclusion

We have completed the configuration procedures to set up the kubernetes nfs persistent volume. With the support of our Server management support services at Skynates we have gone through the whole setup process.
