1. k8s is ready
2. argocd is ready and logged in

installation

1. prepare local-static-provisioner.yaml

   • apiVersion: argoproj.io/v1alpha1
     kind: Application
     metadata:
       name: local-static-provisioner
     spec:
       syncPolicy:
         syncOptions:
         - CreateNamespace=true
       project: default
       source:
         repoURL: https://kubernetes-sigs.github.io/sig-storage-local-static-provisioner
         chart: local-static-provisioner
         targetRevision: 2.0.0
         helm:
           releaseName: local-static-provisioner
           values: |
             rbac:
               create: true
             serviceAccount:
               create: true
             setPVOwnerRef: true
             mountDevVolume: false
             image: registry.k8s.io/sig-storage/local-volume-provisioner:v2.6.0
             classes:
             - name: local-disks
               hostDir: /data/local-static-provisioner
               volumeMode: Filesystem
               fsType: ext4
               namePattern: '*'
               blockCleanerCommand:
               - /scripts/shred.sh
               - 2
               storageClass:
                 isDefaultClass: true
             serviceMonitor:
               enabled: false
       destination:
         server: https://kubernetes.default.svc
         namespace: provisioner
     
     

2. apply to k8s

   • kubectl -n argocd apply -f local-static-provisioner.yaml
     

3. sync by argocd

   • argocd app sync argocd/local-static-provisioner
     

4. configure local volumes is required for not support dynamic provisioning
   • with mount --bind to mount the directories

     • HOSTNAME=$(hostname)
       for index in $(seq 1 3)
       do
           sudo mkdir -p /data/virtual-disks/$HOSTNAME-volume-$index
           sudo mkdir -p /data/local-static-provisioner/$HOSTNAME-volume-$index
           sudo mount --bind /data/virtual-disks/$HOSTNAME-volume-$index /data/local-static-provisioner/$HOSTNAME-volume-$index
       done
       

   • with devices directly

     • HOSTNAME=$(hostname)
       sudo mount /dev/sdb1 /data/local-static-provisioner/$HOSTNAME-volume-dev-sdb1
       

5. check storage class

   • kubectl get sc
     

6. check pv status

   • kubectl get pv
