Rust bootstrapper: https://github.com/libp2p/rust-libp2p/tree/master/misc/server

Requirements of a bootstrap node

• The Peer IDs of the default bootstrap nodes are set explicitly, to assert that you only trust a specific peer at a given ip or dns entry.
  • This makes it harder for attackers to spoof or otherwise MITM attack, as they would also have to compromise our infrastructure to steal the private key behind the Peer ID.
• Defaults
  • The default addresses for the bootstrap nodes are set in the ipfs/go-ipfs-config configuration

Start the bootstrapper

$ npx --package=@libp2p/amino-dht-bootstrapper -- amino

Options:
      --config <CONFIG>              Path to IPFS config file (required)
      --metrics-path <METRICS_PATH>  Metric endpoint path [default: /metrics]
      --metrics-port <PORT>          Metric endpoint path [default: 8888]
      --enable-kademlia              Whether to run the libp2p Kademlia protocol and join the IPFS DHT
      --enable-autonat               Whether to run the libp2p Autonat protocol
      --api-port <PORT>              Port to serve the RPC API [default: 8899]
      --api-host <HOST>              Host to serve the RPC API on [default: 127.0.0.1]
  -h, --help                         Print help

RPC API

To make a request via CURL, you can use the following command:

# run garbage collection
$ curl http://${HOST}:${RPC_PORT}/api/v0/nodejs/gc

# execute a heapdump
$ curl http://${HOST}:${RPC_PORT}/api/v0/nodejs/heapdump

# change the log level
$ curl http://${HOST}:${RPC_PORT}/api/v0/nodejs/log?namespace=libp2p:*

Please note that the RPC API server only listens on the loopback interface (127.0.0.1) by default. If you decide to change the api-host option, please make sure that the RPC API server is only used for development purposes and is not accessible publicly.

Config file example

A config file will be generated for you automatically, and stored at $HOME/.config/@libp2p/amino-dht-bootstrapper/config.json. The default config we generate looks like this:

{
  "addresses": {
    "announce": [],
    "noAnnounce": [],
    "listen": [
      "/ip4/0.0.0.0/tcp/4003/ws",
      "/ip4/0.0.0.0/tcp/4001",
      "/ip6/::/tcp/4004/ws",
      "/ip6/::/tcp/4001",
      "/ip4/0.0.0.0/udp/4002/webrtc"
    ]
  },
  "bootstrap": {
    "list": [
      "/dns4/am6.bootstrap.libp2p.io/tcp/443/wss/p2p/QmbLHAnMoJPWSCR5Zhtx6BHJX9KiKNN6tpvbUcqanj75Nb",
      "/dns4/sg1.bootstrap.libp2p.io/p2p/QmcZf59bWwK5XFi76CZX8cbJ4BhTzzA3gU1ZjYZcYW3dwt",
      "/dns4/sv15.bootstrap.libp2p.io/p2p/QmNnooDu7bfjPFoTZYxMNLWUQJyrVwtbZg5gBMjTezGAJN"
    ]
  },
  "privateKey": "generated by `auto-config.ts`",
  "connectionManager": {
    "inboundConnectionThreshold": 100,
    "maxIncomingPendingConnections": 100,
    "maxConnections": 500
  }
}

Building the Docker Image

Building should be straightforward from the root of the repository:

$ docker build . --tag amino

Running the docker image (once built):

$ docker run -it amino

By default, the config file is stored at $HOME/.config/@libp2p/amino-dht-bootstrapper/config.json. You can mount this file into the container by running:

$ docker run -v $HOME/.config/@libp2p/amino-dht-bootstrapper/:/root/.config/@libp2p/amino-dht-bootstrapper/ -it amino

To pass args:

$ docker run -it amino [--enable-kademlia] [--enable-autonat]

To expose the metrics port:

$ docker run -p 8888:8888 -it amino

Running the docker image with monitoring:

$ docker compose --profile dashboard up -d
