Run a local node using Docker with Nethermind client

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

Set up

Verify that prerequisites are installed:

docker --version 
docker-compose --version

Create working directory

mkdir data_dir

Create 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
EOF

Start container:

docker-compose up -d

Examine logs:

docker-compose logs --tail 20 nethermind

The log output should be similar to the following
