# Mount S3 storage vào K8S cluster

```{admonition} Pre-condition
*   Đã tạo S3 pool.
*   Đã tạo ACL với quyền read & write cho tất cả bucket.
*   Đã tạo K8S.
```

**Các bước thực hiện:**
----------

### Bước 1. Cài đặt Helm

Link cài đặt: <a href="https://helm.sh/docs/intro/install/" target="_blank">https://helm.sh/docs/intro/install/</a>

### Bước 2. Deploy CSI-S3 trên K8S

```
helm repo add yandex-s3 https://yandex-cloud.github.io/k8s-csi-s3/charts
helm repo update
helm show values yandex-s3/csi-s3 > values.yaml
```

Chỉnh sửa các thông số **accesskey**, **secretkey**, **endpoint** trong file **values.yaml**

```

Deploy CSI-S3 trong K8S 

```
helm --kubeconfig={name_file_kubeconfig} upgrade --install csi-s3 yandex-s3/csi-s3 --namespace storage --create-namespace --values values.yaml
```

### Bước 3. Kiểm tra việc mount S3 storage trên K8S

Tạo file **pvc.yaml** với nội dung:

```yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  namespace: storage
  name: sang-pvc-s3
spec:
  storageClassName: csi-s3
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 2Gi
```

Chạy câu lệnh tạo pvc: 

```
kubectl --kubeconfig={name_file_kubeconfig} apply -f pvc.yaml
```

```{div} sd-fs-5 sd-text-primary
Result:
```
