Azure Storage Blob services support.

Configuration

  • root: Set the work dir for backend.
  • container: Set the container name for backend.
  • endpoint: Set the endpoint for backend.
  • account_name: Set the account_name for backend.
  • account_key: Set the account_key for backend.

Refer to Builder’s public API docs for more information.

Environment

  • OPENDAL_AZBLOB_ROOT
  • OPENDAL_AZBLOB_CONTAINER
  • OPENDAL_AZBLOB_ENDPOINT
  • OPENDAL_AZBLOB_ACCOUNT_NAME
  • OPENDAL_AZBLOB_ACCOUNT_KEY

Example

This example works on Azurite for local developments.

Start local blob service

docker run -p 10000:10000 mcr.microsoft.com/azure-storage/azurite
az storage container create --name test --connection-string "DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;"

Init OpenDAL Operator

Via Environment

Set environment correctly:

export OPENDAL_AZBLOB_ROOT=/path/to/dir/
export OPENDAL_AZBLOB_CONTAINER=test
export OPENDAL_AZBLOB_ENDPOINT=http://127.0.0.1:10000/devstoreaccount1
export OPENDAL_AZBLOB_ACCOUNT_NAME=devstoreaccount1
export OPENDAL_AZBLOB_ACCOUNT_KEY=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==
use std::sync::Arc;

use anyhow::Result;
use opendal::Object;
use opendal::Operator;
use opendal::Scheme;

#[tokio::main]
async fn main() -> Result<()> {
    let op: Operator = Operator::from_env(Scheme::Azblob)?;

    // Create an object handle to start operation on object.
    let _: Object = op.object("test_file");

    Ok(())
}

    // `Accessor` provides the low level APIs, we will use `Operator` normally.
    let op: Operator = Operator::new(builder.build()?);

    // Create an object handle to start operation on object.
