Mise en place d'un cluster k8s 3 noeuds
COngifurer le serveur NFS

Configurer le pool de stockage

 apt install lvm2
 
 fdisk /dev/sdb
 pvcreate /dev/sdb1
 vgcreate data /dev/sdb1
 lvcreate -n k8s_data -L 50G data
 mkfs.ext4 /dev/data/k8s_data
 mkdir -p /data/k8s
/etc/fstab :
/dev/data/k8s_data   /data/k8s ext4 defaults 0 0

mount /data/k8s/
root@k8snfs:~# lsblk
sdb                 8:16   0   50G  0 disk 
└─sdb1              8:17   0   50G  0 part 
  └─data-k8s_data 254:0    0   45G  0 lvm  /data/k8s

Configure NFS

apt update
apt install nfs-kernel-server

/etc/idmapd.conf :
[General]
Domain = zayad.k8s

/etc/exports :
/data/k8s/ 192.168.1.0/24(rw,no_root_squash)


systemctl restart nfs-server
