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.

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

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.

Running Graph Node on an Macbook M1

We do not currently build native images for Macbook M1, which can lead to processes being killed due to out-of-memory errors (code 137). Based on the example docker-compose.yml is possible to rebuild the image for your M1 by running the following, then running docker-compose up as normal:

Important Increase memory limits for the docker engine running on your machine. Otherwise docker build command will fail due to out of memory error. To do that, open docker-desktop and go to Resources/advanced/memory.

# Remove the original image
docker rmi graphprotocol/graph-node:latest

# Build the image
./docker/build.sh

# Tag the newly created image
docker tag graph-node graphprotocol/graph-node:latest
