# Storage Options

Currently, these are the supported object storage. Each `source` attribute can be configured like this below.

#### Local

```json
{
  "files": {
    "source": "local",
    "path": <path-to-project-folder>
  }
}
```

#### Google Cloud Storage

`config/google-cloud-storage/config.json`

```json
{
  "credentials": {
    "gcs": { "gcsCredentialJson": "config/google-cloud-storage/credential.json" }
  },
  "create": {
    "files": {
      "source": "gcs",
      "bucketName": "my-bucket",
      "prefix": "projects"
    }
  }
}
```

To fully use Robosaur with a GCS bucket, we can use the `Storage Object Admin` role.\
The specific IAM permissions required are as follows:

* storage.objects.list
* storage.objects.get
* storage.objects.create - to save export results to GCS bucket
* storage.objects.delete - used with storage.objects.create to update the statefile

#### Amazon S3 Buckets

`config/s3/config.json`

```json
{
  "credentials": {
    "s3": {
      "s3Endpoint": "s3.amazonaws.com",
      "s3Port": 443,
      "s3AccessKey": "accesskey",
      "s3SecretKey": "secretkey",
      "s3UseSSL": true,
      "s3Region": "bucket-region-or-null"
    }
  },
  "projectState": {
    "source": "s3",
    "bucketName": "my-bucket",
    "path": "path/to/stateFile.json"
  }
}
```

`s3Region` is an optional parameter, indicating where your S3 bucket is located.\
However, we have encountered some cases where we got `S3: Access Denied` error when it is not defined.\
We recommend setting this property whenever possible.\
Usually, these are identified by access keys starting with `ASIA...`

To fully use Robosaur with S3 buckets, these are the IAM Roles required:

* s3:GetObject
* s3:GetObjectAcl
* s3:PutObject
* s3:PutObjectAcl
* s3:DeleteObject

#### Azure Blob Storage

`config/azure-blob-storage/config.json`

```json
{
  "credentials": {
    "azure": {
      "connectionString": "my-connection-string-from-storage-account",
      "containerName": "my-container-name"
    }
  },
  "projectState": {
    "source": "azure",
    "bucketName": "my-container-name",
    "path": "path/to/stateFile.json"
  },
}
```

Both `connectionString` and `containerName` are required.

You can obtain your `connectionString` by copying one of the connection strings from your Azure Storage Account.

The `containerName` is where you would upload your projects, inside a `projects` folder.
