Création du namespace Minecraft :

kubectl create namespace minecraft

Déclaration du PVC :

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: minecraft-srv-01-pvc
  namespace: minecraft
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: longhorn
  resources:
    requests:
      storage: 10Gi
EOF
