Running subgraph in local with Docker

Running subgraph in local

How to run

Create a .env base on .env.example.

Make sure that all of the following port are available:

• 8000, 8001, 8020, 8030, 8040: port for subgraph
• 5001: ipfs

Run docker-compose build and docker-compose up.

• If you are using Mac M1, you might need to clone graph-node repo and rebuild the image, see this: https://github.com/graphprotocol/graph-node/tree/master/docker#running-graph-node-on-an-macbook-m1

After the whole system is up, you can use:

• http://localhost:8000 to access the subgraph.

After running

• git submodule init

• git submodule update

• Go to example-subgraph folder and run:

yarn
yarn codegen
yarn create-local
yarn deploy-local

• Then you should see the subgraph docker will start to sync the example subgraph.

• Go to http://127.0.0.1:8000/subgraphs/name/example to make some query!

Setting

In docker-compose.yml, ETHEREUM_POLLING_INTERVAL is set to 10 seconds to reduce number of requests to the RPC node.

Might need to changes it to a smaller value later (default is 0.5 secs)

Note

Subgraph will use a lot of request to the RPC, so make sure that you have enough quota on your account.
