Graph Node Docker Image

Preconfigured Docker image for running a Graph Node.

Usage

docker run -it \
  -e postgres_host=<HOST> \
  -e postgres_port=<PORT> \
  -e postgres_user=<USER> \
  -e postgres_pass=<PASSWORD> \
  -e postgres_db=<DBNAME> \
  -e ipfs=<HOST>:<PORT> \
  -e ethereum=<NETWORK_NAME>:<ETHEREUM_RPC_URL> \
  graphprotocol/graph-node:latest

Example usage

docker run -it \
  -e postgres_host=host.docker.internal \
  -e postgres_port=5432 \
  -e postgres_user=graph-node \
  -e postgres_pass=oh-hello \
  -e postgres_db=graph-node \
  -e ipfs=host.docker.internal:5001 \
  -e ethereum=mainnet:http://localhost:8545/ \
  graphprotocol/graph-node:latest

Docker Compose

The Docker Compose setup requires an Ethereum network name and node to connect to. By default, it will use mainnet:http://host.docker.internal:8545 in order to connect to an Ethereum node running on your host machine. You can replace this with anything else in docker-compose.yaml.

Note for Linux users: On Linux, host.docker.internal is not currently supported. Instead, you will have to replace it with the IP address of your Docker host (from the perspective of the Graph Node container). To do this, run:

CONTAINER_ID=$(docker container ls | grep graph-node | cut -d' ' -f1) docker exec $CONTAINER_ID /bin/bash -c 'apt install -y iproute2 && ip route' | awk '/^default via /{print $3}'

This will print the host's IP address. Then, put it into `docker-compose.yml`:

sed -i -e 's/host.docker.internal//g' docker-compose.yml

After you have set up an Ethereum node—e.g. Ganache or Parity—simply clone this repository and run

docker-compose up

This will start IPFS, Postgres 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/subgraphs/name/<subgraph-name>
  • WebSockets: ws://localhost:8001/subgraphs/name/<subgraph-name>
  • Admin: http://localhost:8020/
• IPFS:
  • 127.0.0.1:5001 or /ip4/127.0.0.1/tcp/5001
• Postgres:
  • postgresql://graph-node:let-me-in@localhost:5432/graph-node

Once this is up and running, you can use graph-cli to create and deploy your subgraph to the running Graph Node.
