Docker Compose

To use the docker-compose.yml configuration in this repository, simply clone this repo and run

docker-compose up

This will start IPFS, Postgres, Parity and Graph Node in Docker and create persistent data directories for IPFS and Postgres in ./data/ipfs and ./data/postgres. You can access these via:

• Graph Node:
  • GraphiQL: http://localhost:8000/
  • HTTP: http://localhost:8000/<subgraph>/graphql
  • WebSockets: ws://localhost:8001/<subgraph>
  • JSON-RPC admin: http://localhost:8020/
• IPFS:
  • 127.0.0.1:5001 or /ip4/127.0.0.1/tcp/5001
• Parity:
  • JSON-RPC: http://localhost:8545/
  • WebSockets: ws://localhost:8546/
• Postgres:
  • postgresql://graph-node:let-me-in@localhost:8545/graph-node

The Parity dev chain included in this setup creates one default account and starts with three additional unlocked account you can use for development and testing (e.g. with Truffle).

In order to use the three unlocked accounts, you have to send money to them from the default account. In a web3 console (e.g. truffle console), run

> # Unlock the default account
> web3.eth.personal.unlockAccount('0x00a329c0648769A73afAc7F9381E08FB43dBEA72', '')
>
> # Send money to the other unlocked accounts
> web3.eth.sendTransaction({from: '0x00a329c0648769A73afAc7F9381E08FB43dBEA72', to:'0xddf8430d91ca7cf8df175813b58865dff2e15bc6', value: 10000000000000000000})
> web3.eth.sendTransaction({from: '0x00a329c0648769A73afAc7F9381E08FB43dBEA72', to:'0xc4ca008b1a769c4330ab6f42f53dc367d0527c60', value: 10000000000000000000})
> web3.eth.sendTransaction({from: '0x00a329c0648769A73afAc7F9381E08FB43dBEA72', to:'0xd49c572ab93dcc58627a70420763de4bdb74d6e8', value: 10000000000000000000})
