# Azure Storage Backend

Welcome to the `Azure Storage backend` plugin!

## Getting started

### Installation

This plugin needs to be added to an existing backstage instance.

```bash
# From your Backstage root directory
yarn add --cwd packages/backend backstage-plugin-azure-storage-backend
```

Create a file called `azure-storage.ts` inside `packages/backend/src/plugins/` and add the following

#### azure-storage.ts

```typescript
import { createRouter } from 'backstage-plugin-azure-storage-backend';
import { Router } from 'express';
import { PluginEnvironment } from '../types';

export default async function createPlugin(
  env: PluginEnvironment,
): Promise<Router> {
  return await createRouter({
    logger: env.logger,
    config: env.config,
  });
}
```

And import the plugin to `packages/backend/src/index.ts`.

## Configuration

Setup Azure Storage accounts in `app-config.yaml`

```yaml
azureStorage:
  blobContainers:
    - accountName: 'storageAccount'
      authType: accessToken
      auth:
        accessToken: 'STORAGE ACCOUNT ACCESS TOKEN'
    - accountName: 'anotherStorageAccount'
      authType: clientToken
      auth:
        tenantId: 'AZURE TENANT ID'
        clientId: 'AZURE CLIENT ID'
        clientSecret: 'AZURE CLIENT SECRET'
```

## Authenticating Storage Account

This Plugin provides 2 types of authentication on your storage account.

### accessToken

When you create a storage account, Azure generates two 512-bit storage account access keys for that account. You can use this access keys to authenticate the Azure storage account ["More Info..."](https://learn.microsoft.com/en-us/azure/storage/common/storage-account-keys-manage?toc=%2Fazure%2Fstorage%2Fblobs%2Ftoc.json&bc=%2Fazure%2Fstorage%2Fblobs%2Fbreadcrumb%2Ftoc.json&tabs=azure-portal)

### clientToken

This method uses the RBAC authentication but only to Azure App Client. ["More info..."](https://learn.microsoft.com/en-us/azure/storage/blobs/assign-azure-role-data-access?tabs=portal)
