1. Setup Environment Variables

# In project root
cp .env.example .env

Edit .env with your values:

CHAINMAKER_PATH=/path/to/chainmaker-go
CHAINMAKER_NODE_HOST=30.177.108.73
CHAINMAKER_NODE_PORT_1=12301
# ... other ports

2. Generate Blockchain Client Config

bash scripts/generate-chainmaker-config.sh

Generates clients/chainmaker.yml from template.

3. Start Services

docker compose up -d

  • engine.defaults.yml: Engine service (Kafka consumer, batch processing, blockchain client)
  • query.defaults.yml: Query service (HTTP port, database, blockchain client)
  • blockchain.defaults.yml: Blockchain client settings (type, connection parameters)

Blockchain Client
