Example for NFS server in Kubernetes

nfs-server.yaml

# Note - an NFS server isn't really a Kubernetes
# concept. We're just creating it in Kubernetes
# for illustration and convenience. In practice,
# it might be run in some other system.

# Create a service to expose the NFS server
# to pods inside the cluster.

kind: Service
apiVersion: v1
metadata:
  name: nfs-service
spec:
  selector:
    role: nfs
  ports:
    # Open the ports required by the NFS server
    # Port 2049 for TCP
    - name: tcp-2049
      port: 2049
      protocol: TCP

    # Port 111 for UDP
    - name: udp-111
      port: 111
      protocol: UDP

---

# Run the NFS server image in a pod that is
# exposed by the service.

kind: Pod
apiVersion: v1
metadata:
  name: nfs-server-pod
  labels:
    role: nfs
spec:
  containers:
    - name: nfs-server-container
      image: cpuguy83/nfs-server
      securityContext:
        privileged: true
      args:
        # Pass the paths to share to the Docker image
        - /exports

Hi matthewpalmer I am trying to use the same and getting connection timeout when pod(nfs client) is coming up.
Error :- Warning FailedMount 1m kubelet, clm-pun-tk241m MountVolume.SetUp failed for volume "nfs-volume" : mount failed: exit status 32

Same here: can replicate the use case described by poster above.

Turns out you need to configure quotad and other services to use static ports. You can modify the docker image via RUN add echo "....." statements (plus the "non-kernel" setup flags), and then make the appropriate port entries in your service's yaml definition, and it works perfectly!

Could you please specify what you have done exactly? I run into the same problem and I am not able to solve it.

I came across this article while looking more into this issues but iam confused as of now https://redblink.com/setup-nfs-server-provisioner-kubernetes/
