This plugin allows services to connect to Apache OpenDAL™. OpenDAL is a data access layer that allows users to easily and efficiently retrieve data from various storage services in a unified way.

Users can connect OpenDAL to access data from a variety of storage services, including: S3, AzBlob (Azure Blob storage), GCS, OSS and so on.

​

Usage

IMPORTANT: Currently Shuttle isn’t able to provision a storage for you (yet). This means you will have to create the storage service first and setup the secrets accordingly.

Add shuttle-opendal to the dependencies for your service by running cargo add shuttle-opendal. This resource will be provided by adding the shuttle_opendal::Opendal attribute to your Shuttle main decorated function.

It returns a opendal::Operator for you to connect the storage service.

​

Example

In the case of an Axum server, your main function will look like this:

use opendal::Operator;
use shuttle_axum::ShuttleAxum;

#[shuttle_runtime::main]
async fn app(
    #[shuttle_opendal::Opendal(scheme = "s3")]
    storage: Operator,
) -> ShuttleAxum {}

​

Parameters

All secrets are loaded from your Secrets.toml file.

For instance, when using s3, you can configure the scheme to s3 and specify the secrets: bucket, access_key_id, and secret_access_key.

Visit the OpenDAL Documentation for more information on how to setup the secrets for the storage service you want to connect to.
