Deploying Provider

About Provider

Provider encrypts the URL and metadata during publish and decrypts the URL when the dataset is downloaded or a compute job is started. It enables the access to data assets by streaming data (and never the URL). It performs checks on chain for buyer permissions and payments. It also Provides compute services (connects to C2D environment). The source code of Provider can be access from here.

Prerequisites

  • Docker and Docker compose are installed. Click here to view guide on installing docker.

Create a working directory

mkdir Provider
cd Provider

Create a `.env` file

Copy the below content into the `.env` file and edit the values as needed.
.env
# Mandatory variables
# Update the value to the appropriate tag from here: https://hub.docker.com/r/oceanprotocol/provider-py/tags
PROVIDER_VERSION=latest
PROVIDER_PRIVATE_KEY=<private-key>
NETWORK_URL=<api-key>
AQUARIUS_URL=<aquarius-url>

Create docker-compose file

Set the value of OCEAN_PROVIDER_WORKERS to 2 or more to avoid a race condition when provider checks whether it should call a remote provider or not.
