Docker Compose SNARK Workers

This example runs a SNARK coordinator and a SNARK worker together using Docker Compose. It includes a one-time init container that generates a wallet key.

Save the following as docker-compose.yml, then start with docker compose up -d. Monitor logs with docker compose logs -f.

services:
  generate_wallet_key:
    image: 'minaprotocol/mina-daemon:3.3.0-8c0c2e6-bullseye-mainnet'
    environment:
      MINA_PRIVKEY_PASS: PssW0rD
    entrypoint: []
    command: >
      bash -c '
        mina advanced generate-keypair --privkey-path /root/.mina-config/keys/wallet-key
        chmod -R 0700 /root/.mina-config/keys
        chmod -R 0600 /root/.mina-config/keys/wallet-key

  mina_snark_coordinator:

    restart: always
    environment:
      MINA_PRIVKEY_PASS: PssW0rD
      MINA_CLIENT_TRUSTLIST: "0.0.0.0/0"

    volumes:
      - './node/mina-config:/root/.mina-config'
    ports:
      - '8302:8302'
    depends_on:
      generate_wallet_key:
        condition: service_completed_successfully
  mina_snark_worker:

    command: >

             --proof-level full
      '
    volumes:
      - './node/mina-config:/root/.mina-config'
    depends_on:
      mina_snark_coordinator:
        condition: service_healthy

To scale additional workers, duplicate the mina_snark_worker service with a different name (e.g. mina_snark_worker_2).
