SushiSwap Subgraph

Setup

Clone required repositories:

laconic-so --stack sushiswap-subgraph setup-repositories --pull

Checkout to a non-default branch in the cloned repos if required:

# Default repo base dir
cd ~/cerc

# Example
cd graph-node
git checkout <your-branch> && git pull

# Remove the corresponding docker image if it already exists
docker image rm cerc/graph-node:local
# Remove any dangling images
docker image prune

Build the container images:

laconic-so --stack sushiswap-subgraph build-containers

Create a deployment

Initialize deployment and create "spec" file:

laconic-so --stack sushiswap-subgraph deploy init --output sushiswap-subgraph-spec.yml

We need to assign a fixed port 8000 for graph-node subgraph GQL endpoint. The values can be customized by editing the "spec" file generated by laconic-so deploy init.

$ cat sushiswap-subgraph-spec.yml
stack: sushiswap-subgraph
ports:
  graph-node:
   - '8000:8000'
   - '8001'
   - '8020'
   - '8030'
...

Create deployment:

laconic-so deploy create --spec-file sushiswap-subgraph-spec.yml --deployment-dir sushiswap-subgraph-deployment

Start the stack

Deploy the stack:

laconic-so deployment --dir sushiswap-subgraph-deployment start

# Note: Remove any existing volumes for the cluster for a fresh start

After all services have started:

Follow graph-node logs:

laconic-so deployment --dir sushiswap-subgraph-deployment logs -f graph-node

Check that the subgraphs have been deployed:

laconic-so deployment --dir sushiswap-subgraph-deployment logs -f sushiswap-subgraph-v3

# Expected output:

# sushigraph-sushiswap-subgraph-v3-1  |
# sushigraph-sushiswap-subgraph-v3-1  |
# sushigraph-sushiswap-subgraph-v3-1  | Done

After graph-node has fetched the latest blocks from upstream, use the subgraph (GQL) endpoints for querying:

# Blocks subgraph endpoint:
http://127.0.0.1:8000/subgraphs/name/sushiswap/blocks/graphql

# v3 subgraph endpoint:
http://127.0.0.1:8000/subgraphs/name/sushiswap/v3-filecoin/graphql

Set environment variables

The graph-node environment variable ETHEREUM_REORG_THRESHOLD can be set in the deployment compose file

$ cat sushiswap-subgraph-deployment/compose/docker-compose-graph-node.yml
services:
  graph-node:
    image: cerc/graph-node:local
    ...
    environment:
      ...
      GRAPH_LOG: debug
      ETHEREUM_REORG_THRESHOLD: 16

Change ETHEREUM_REORG_THRESHOLD to desired value

To restart graph-node with updated values, we need to restart only graph-node compose services

Comment sushiswap-subgraph-v3 pod in stack.yml so that subgraphs are not deployed again

$ cat sushiswap-subgraph-deployment/stack.yml
version: "1.0"
name: sushiswap-subgraph
...
pods:
  - graph-node
  # - sushiswap-subgraph-v3

Stop the stack first

laconic-so deployment --dir sushiswap-subgraph-deployment stop

Start the stack again (will not start sushiswap-subgraph-v3 pod)

laconic-so deployment --dir sushiswap-subgraph-deployment start

To check if environment variable has been updated in graph-node container

$ laconic-so deployment --dir sushiswap-subgraph-deployment exec graph-node bash
root@dc4d3abe1615:/# echo $ETHEREUM_REORG_THRESHOLD
16

Clean up

Stop all the services running in background run:

laconic-so deployment --dir sushiswap-subgraph-deployment stop

Clear volumes created by this stack:

laconic-so deployment --dir sushiswap-subgraph-deployment stop --delete-volumes
