provider-py

REST API for provider of data services

Starting the server locally

1. Clone the repo

git clone git@github.com:oceanprotocol/provider-py.git
cd provider-py/

2. Virtual env (optional)

Before running it locally we recommend to set up virtual environment:

virtualenv venv -p python3.6
# OR: python -m venv venv
source venv/bin/activate 

3. Requirements

Install all the requirements:

pip install -r requirements_dev.txt

4. Dependencies

Metadata store (Aquarius). Do one of the following:

• Run Aquarius locally, see https://github.com/oceanprotocol/aquarius
• Point to a remote instance such as https://aquarius.marketplace.dev-ocean.com. In this case replace the aquarius.url option in the config.ini file with the appropriate URL.

Ethereum network. Do one of the following:

• Run ganache-cli
• Point to rinkeby testnet or any other ethereum network

Make sure that ocean contracts (https://github.com/oceanprotocol/contracts) are deployed to the your network of choice. Update the network.url option in the config.ini file with the proper network URL. For now it must be a URL, a simple network name (e.g. mainnet) will be supported in the future.

5. Start the provider server

pip install -r requirements_dev.txt
export FLASK_APP=ocean_provider/run.py
export CONFIG_FILE=config.ini
export PROVIDER_ADDRESS="your ethereum address goes here"
# Set one of the following
export PROVIDER_KEY="the private key"
export PROVIDER_ENCRYPTED_KEY="The encrypted key json from the keyfile"
export PROVIDER_KEYFILE="path to the keyfile which has the encrypted key"
# and set the password if using either PROVIDER_KEYFILE or PROVIDER_ENCRYPTED_KEY
export PROVIDER_PASSWORD="password to allow decrypting the encrypted key"

flask run --port=8030
