Docker Compose Seed Peer (Devnet)

This example demonstrates how to run a Mina Seed node using Docker Compose for the Devnet network. This Docker Compose setup includes a Mina seed node, and a script to generate a libp2p key.

Copy and paste the provided configuration into a docker-compose.yml file. Then run docker compose up -d to start the services, and use docker compose logs -f to monitor the logs.

services:
  generate_libp2p_key:
    image: 'gcr.io/o1labs-192920/mina-daemon:3.0.0-dc6bf78-bullseye-devnet'
    environment:
      MINA_LIBP2P_PASS: PssW0rD
    entrypoint: []
    command: >
      bash -c '
        mina libp2p generate-keypair -privkey-path /data/.mina-config/keys/libp2p-key
        chmod -R 0700 /data/.mina-config/keys
        chmod -R 0600 /data/.mina-config/keys/libp2p-key
      '
    volumes:
      - './node/mina-config:/data/.mina-config'
  mina_node:
    image: 'gcr.io/o1labs-192920/mina-daemon:3.0.0-dc6bf78-bullseye-devnet'
    restart: always
    environment:
      MINA_LIBP2P_PASS: PssW0rD
    entrypoint: []
    command: >
      bash -c '
        mina daemon \
             --peer-list-url https://bootnodes.minaprotocol.com/networks/devnet.txt \
             --libp2p-keypair /data/.mina-config/keys/libp2p-key \
             --seed
      '
    volumes:
      - './node/mina-config:/data/.mina-config'
    depends_on:
      generate_libp2p_key:
        condition: service_completed_successfully

To retrieve the status of the Mina Node, run docker compose exec mina_node mina client status

In the client status, you should also see the Adresses and ports section.

Addresses and ports:
    External IP:    35.197.32.58
    Bind IP:        0.0.0.0
    Libp2p PeerID:  12D3KooW9wsoTH3RvWJntT8CnQAMKAYgd1DztxumTaeH3TikQ6b3
    Libp2p port:    8302
    Client port:    8301

Base on the above output, you can build you "relay circuit" address as follows:

/ip4/35.197.32.58/tcp/8302/p2p/12D3KooW9wsoTH3RvWJntT8CnQAMKAYgd1DztxumTaeH3TikQ6b3

If you prefer using a DNS instead of an IP address, you can use the following format:

/dns4/seed.example.com/tcp/8302/p2p/12D3KooW9wsoTH3RvWJntT8CnQAMKAYgd1DztxumTaeH3TikQ6b3

Finally, you can add the relay circuit address the official Mina Seed Peers list by submitting a pull request to the MinaFoundation/seeds repository
