# Graph Node Docker Image Preconfigured Docker image for running a Graph Node. ## Usage ```sh docker run -it \ -e postgres_host=<HOST>[:<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 ```sh docker run -it \ -e postgres_host=host.docker.internal: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 '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/<IP ADDRESS>/g' docker-compose.yml > ``` After you have set up an Ethereum node—e.g. Ganache or Parity—simply clone this repository and run ```sh 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: - `` or `/ip4/` - 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.
