This section describes minimal setup to run an RPC node locally or on the server using Docker container run with docker-compose. This is solely for development purposes, it's not a production grade recommendation.
See Nethermind documentation for Docker: https://docs.nethermind.io/get-started/installing-nethermind#docker-container
Verify that prerequisites are installed:
docker --version
docker-compose --version Create working directory
mkdir data_dirCreate docker-compose.yaml file
cat > docker-compose.yaml << 'EOF'
version: '3.8'
services:
nethermind:
image: nethermind/nethermind:1.25.4
restart: always
command:
--config volta -dd /nethermind/data_dir
# For EnergyWebChain network
# --config energyweb -dd /nethermind/data_dir
volumes:
- ./data_dir:/nethermind/data_dir
ports:
- 8545:8545
- 8546:8546
- 30303:30303
- 30303:30303/udp
EOFStart container:
docker-compose up -dExamine logs:
docker-compose logs --tail 20 nethermindThe log output should be similar to the following
