```powershell
# ストレージアカウントを作成（パブリックBLOBアクセスを有効化）
az storage account create `
  --name $storageAccountName `
  --resource-group $resourceGroup `
  --location $location `
  --sku Standard_LRS `
  --kind StorageV2 `
  --allow-blob-public-access true

# ストレージアカウントのIAM設定からストレージ BLOB データ共同作成者ロールを割り当て（Azure Portal作業）※反映に1～2分かかります

# コンテナを作成（パブリックアクセス許可）
az storage container create `

```

### ファイルをBLOBストレージにアップロード

```powershell
# DSCパッケージをアップロード
