# Setting the S3 bucket for file uploads and redactions

For a self-hosted instance, you configure an S3 bucket to use to store dataset files and individual files that you use the Textual SDK to redact. If an S3 bucket is not configured, then:

* The dataset and individual redacted files are stored in the Textual application database.
* You cannot use Amazon Textract for [PDF and image processing](https://docs.tonic.ai/textual/textual-install-administer/configuring-textual/enable-and-configure-textual-features/textual-config-pdf-image). If you configured Textual to use Amazon Textract, Textual instead uses Tesseract.

The authentication credentials for the S3 bucket include:

* The AWS Region where the S3 bucket is located.
* An AWS access key that is associated with an IAM user or role.
* The secret key that is associated with the access key.

To provide the authentication credentials, you can either:

* Provide the values directly as environment variable values.
* Use the instance profile of the compute instance where Textual runs.

For an example IAM role that has the required permissions, go to [#file-upload-example-iam-role](https://docs.tonic.ai/textual/textual-install-administer/configuring-textual/pipelines-example-iam-roles#file-upload-example-iam-role "mention").

## Docker <a href="#pipeline-file-upload-docker" id="pipeline-file-upload-docker"></a>

In **.env**, add the following settings:

`SOLAR_INTERNAL_BUCKET_NAME= <S3 bucket path>`

`AWS_DEFAULT_REGION= <AWS Region>`

`AWS_ACCESS_KEY_ID= <AWS access key>`

`AWS_SECRET_ACCESS_KEY= <AWS secret key>`

If you use the instance profile of the compute instance, then only the bucket name is required.

## Kubernetes <a href="#pipeline-file-upload-kubernetes" id="pipeline-file-upload-kubernetes"></a>

In **values.yaml**, within `env: { }` under both `textual_api_server` and `textual_worker`, add the following settings:

`SOLAR_INTERNAL_BUCKET_NAME`

`AWS_DEFAULT_REGION`

`AWS_ACCESS_KEY_ID`

`AWS_SECRET_ACCESS_KEY`

For example, if no other environment variables are defined:

```json
  env: {
        "SOLAR_INTERNAL_BUCKET_NAME": "<S3 bucket path>",
        "AWS_DEFAULT_REGION": "<AWS Region>",
        "AWS_ACCESS_KEY_ID": "<AWS access key>",
        "AWS_SECRET_ACCESS_KEY": "<AWS secret key>"
       }
```

If you use the instance profile of the compute instance, then only the bucket name is required.
