UBUNTU18+KVM+VAGRANT+KUBERNETES 9)nfs server and nfs provisioning from k8s
This short article explains how to install kubectl PersistentVolume and PersistentVolumeClaim using outer nfs server.
We should prepare nfs node.(10.1.0.7 is my nfs server installed kvm env.
Prerequisites)
Vagrant knowledge. Beforhand articles about Ubuntu18+k8s+kvm+vagrant on my blog. Linux Command.
I refered below link. That is very awesome github. Thank you.

1.Nfs sERver install on centos7. Adding vagrant node centos7 for nfs server. - 10.1.0.7 is nfs server
config.vm.define "nfserver" do |nfserver|
nfserver.vm.box = "centos/7"
nfserver.vm.provision "shell", path: "check_key.sh"
nfserver.vm.provision "file", source: "id_rsa",destination: "/home/vagrant/.ssh/id_rsa"
nfserver.vm.provision "shell", :path => "k8s_docker_install.sh"
nfserver.vm.network "private_network", ip:"10.1.0.7"
nfserver.vm.provision "annfs", type:"ansible" do |ansible|
ansible.playbook = "nfsFileSystem.yaml"
end
nfserver.vm.provision "nfsdocker", type:"shell", :path => "nfsDocker.sh"
nfserver.vm.host_name = "nfserver"
nfserver.vm.provider :libvirt do |lv|
lv.storage_pool_name = "data"
lv.cpus = 1
lv.memory = 512
lv.storage :file, :size => '5G', :type => 'raw'
end
end

4. Authorization. In my case I installed kubernets 1.15, by default RBAC is configured.
So I need to configure authorization process.
By default RBAC is on.

I already deploy wordpress with below ...configuration.
