Lisk Service Configuration Reference

# Must be identical for all micro-serivces
# Make sure that all micro-services are able to connect with the common Redis
SERVICE_BROKER=redis://localhost:6379/0

SERVICE_LOG_STDOUT=true   # Asynchronous console output (non-blocking, preferred)
SERVICE_LOG_CONSOLE=false # console.log() output, only for debug
SERVICE_LOG_FILE=false    # file path ex. ./logs/service.log
SERVICE_LOG_GELF=false    # GELF output for remote logging ex. Graylog localhost:12201/udp
SERVICE_LOG_LEVEL=info    # Default log level

# Port that provides the possibility to connect with Lisk Service
# For HTTP and WebSocket
PORT=9901
HOST=0.0.0.0   # or 127.0.0.1 for localhost

# Enable certain APIs (HTTP & WebSocket)
# Use comma separated list

ENABLE_WS_API=rpc,rpc-v1,blockchain,rpc-v2

# Enabled requires clients to pass the full JSON-RPC envelope.
# Disabled allows clients to pass only `method` in the request
# and does not check the envelope whether it has `jsonrpc: "2.0"` or not.
