Autoretrieve

Autoretrieve is a standalone gateway server / Bitswap provider that bridges Filecoin Graphsync content over to Bitswap clients.

When a Bitswap client requests data from Autoretrieve, Autoretrieve asks either Estuary or an STI indexer which Filecoin service providers are hosting it, starts a retrieval deal with a selected SP, and streams the incoming blocks to the Bitswap client.

Usage

Autoretrieve uses Docker with Buildkit for build caching. Docker rebuilds are quite fast, and it is usable for local development. Check the docker-compose documentation for more help.

$ DOCKER_BUILDKIT=1 docker-compose up

You may optionally set FULLNODE_API_INFO to a custom fullnode's WebSocket address. The default is FULLNODE_API_INFO=wss://api.chain.love.

By default, config files and cache are stored at ~/.autoretrieve. When using docker-compose, a binding is created to this directory. This location can be configured by setting AUTORETRIEVE_DATA_DIR.

Internally, the Docker volume's path on the image is /root/.autoretrieve. Keep this in mind when using the Docker image directly.

Configuration

Some CLI flags and corresponding environment variables are available for basic configuration.

For more advanced configuration, config.yaml may be used. It lives in the autoretrieve data directory, and will be automatically generated by running autoretrieve. It may also be manually generated using the gen-config subcommand.

Configurations are applied in the following order, from least to most important:

• YAML config
• Environment variables
• CLI flags
