You can optionally add the `user` and `password` properties to use a user system.

### Amazon S3
|
||||
|
||||
To use [Amazon S3](https://aws.amazon.com/s3/) as a storage system, you must
|
||||
install the `aws-sdk` package via npm:
|
||||
|
||||
`npm install aws-sdk`
|
||||
|
||||
Once you've done that, your config section should look like this:
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "amazon-s3",
|
||||
"bucket": "your-bucket-name",
|
||||
"region": "us-east-1"
|
||||
}
|
||||
```
|
||||
|
||||
Authentication is handled automatically by the client. Check
|
||||
[Amazon's documentation](https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-credentials-node.html)
|
||||
for more information. You will need to grant your role these permissions to
|
||||
your bucket:
|
||||
|
||||
```json
|
||||
{
|
||||
"Version": "2012-10-17",
|
||||
"Statement": [
|
||||
{
|
||||
"Action": [
|
||||
"s3:GetObject",
|
||||
"s3:PutObject"
|
||||
],
|
||||
"Effect": "Allow",
|
||||
"Resource": "arn:aws:s3:::your-bucket-name-goes-here/*"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
