A local Graph network for debugging & integration tests.

Epochs are set up to be 554 blocks long, use scripts/mine-block.sh to advance (foundry installation required)

• The network id for manifests is hardhat.

1. install Docker & Docker Compose
2. docker compose down && docker compose up --build
3. install foundry on the host for mining blocks

• docker compose up --build -d ${service}
• docker logs -f ${service}
• docker system prune
• source .env

• Foundry docs: https://book.getfoundry.sh/

• esplr block explorer available at: http://localhost:3000

• cat file via curl:

  curl -X POST "http://localhost:5001/api/v0/cat?arg=f1220d6b169dcf83bfe0f615baa2d83e9adf77d520b52faf18a759eb7277b6d66fa7f"

• cat file via CLI:

  ipfs --api=/ip4/127.0.0.1/tcp/5001 cat QmagRyTMp4qcRb8fJufk7urNwCQmmUEB9mC6nxHQuKwydb

• note: if you have a hex digest, a valid CID for it is the hex digits prefixed by f1220. For example, 0xd6b169dcf83bfe0f615baa2d83e9adf77d520b52faf18a759eb7277b6d66fa7f -> f1220d6b169dcf83bfe0f615baa2d83e9adf77d520b52faf18a759eb7277b6d66fa7f

The following components allow building from source by overriding docker-compose.yml:

• graph-node
• graph-contracts
• indexer-agent

Please refer to overrides/README.md for instructions.

The following components allow building from source by cloning them with submodules:

• indexer-service
• tap-agent

Building from source requires the Git submodules to be initialized first:

• git submodule update --init --recursive

And then select the wrapper-dev target when building the Docker image in the docker-compose.yaml file.

  indexer-service:
    container_name: indexer-service
    build: { 
-     target: "wrapper", # Set to "wrapper-dev" for building from source
+     target: "wrapper-dev", # Set to "wrapper-dev" for building from source
      context: indexer-service,
    }

  tap-agent:
    container_name: tap-agent
    build: { 
-     target: "wrapper", # Set to "wrapper-dev" for building from source
+     target: "wrapper-dev", # Set to "wrapper-dev" for building from source
      context: tap-agent,
    }

Gateway error:

ERROR graph_gateway::network::subgraph_client: indexer=http://indexer-service:7601/subgraphs/id/Qmc2CbqucMvaS4GFvt2QUZWvRwSZ3K5ipeGvbC6UUBf616 network_subgraph_query_err="response too far behind"

Solution: This happens because the network does not automine, can be fixed by running scripts/mine-block.sh 10
