Run a mirror node🔗

The utility of a mirror node is to expose a RPC endpoint to submit extrinsincs and get blockchain data. It can be an archive node if it keeps a copy of the whole storage for each block or a standard node if it enables storage pruning and only keeps state transitions. Both can be used for synchronization but only archive nodes can be used to retreive blockchain information at any given block.

Install🔗

Docker🔗

We chose docker as the standard way to deploy a node. Distribution packages are not yet provided. First install docker on your platform.

Compose file🔗

Then use the following docker-compose.yml example file:

services:
  duniter-mirror:
    image: duniter/duniter-v2s-gdev:xxx             # <----
    restart: unless-stopped
    ports:
      # Prometheus
      - 9615:9615
      # RPC API
      - 9944:9944
      # p2p
      - 30333:30333
    volumes:
      - data-mirror:/var/lib/duniter/
    environment:
      - DUNITER_CHAIN_NAME=yyy                      # <----
      - DUNITER_NODE_NAME=zzz                       # <----

volumes:
  data-mirror:

Replace -gdev by the docker image of the network you want to use. You can found the available images here: https://hub.docker.com/u/duniter

Replace xxx by the Duniter version you want to use. Use sha-latest to use the latest version. If you are using ARM architecture (raspberry pi for example), ask on the forum which image should be used.

Replace yyy by the name of the chain you want to use. Only gdev, gtest and g1 are available at the moment and only gdev will work since no chainspec exist for the other yet.

Replace zzz by the name of your node on chain. It is useful to include your name for other people to recognize you easily and an identifier of the node if you run multiple.

For more info about how to configure your node using Docker, read configure (docker).

Start node🔗

When done, in the folder of this docker-compose.yml file, run docker compose up to start your node. You should see logs like this:

It downloaded the good docker image, started the node, and started synchronization.

⚙️  Syncing 706.1 bps, target=#587675 (5 peers), best: #14288 (0x12e1…c95e), finalized #13824 (0xf539…7329), ⬇ 237.8kiB/s ⬆ 2.5kiB/s

The line above tells you the state of the synchronization. You get the target block of the network, the block your are currently at, and the average sychronization speed (here 706 blocks per second).

Once you are happy with the result, you can safely interrupt Duniter (with Ctrl+C) and start it again in background with:

docker compose up --detach

Then you can inspect your node in polkadotjs app locally or remotely depending on where you started your node.

For more info about how to interact with Duniter through Docker, read configure (docker).

Binary🔗

You can download a pre-build binary (no official support yet) or compile Duniter with:

# choose the branch corresponding to your target network {gdev, gtest, g1}
git clone https://git.duniter.org/nodes/rust/duniter-v2s.git --branch BRANCH --depth 1
# build duniter binary
cargo build --release

This can take ~1h or so depending on your internet connexion and computing power. Then you get a binary in ./target/release/duniter.

# read help
duniter --help | less
# start node
duniter --chain=gdev

You will find in the help everything you need to configure and run your node.

Debian🔗

We have a debian package for Duniter v2 currently in test stage. Documentation is available on the repo https://git.duniter.org/nodes/rust/duniter-v2s/-/blob/master/docs/user/installation_debian.md. We give below a more detailed example for a mirror node.

Download debian package from http://pagu.re/ipfs/QmUyTPcGFs5p1LUVk6c2qqfsTNKzo6wmK9J7Zij9XmDwDi?filename=duniter_0.8.0-1_amd64.deb (temporary link, TODO: replace by https://git.duniter.org/nodes/rust/duniter-v2s/-/releases when available and non-expiring artifact). Then install and configure it:

# download with curl
curl https://bafybeidcspicuabhgbzktzigi4jjltf6h4jvly4xf5e7tcfajddi3wh53e.ipfs.pagu.re/ -o duniter_0.8.0-1_amd64.deb
# install with apt
sudo apt install ./duniter_0.8.0-1_amd64.deb
# configure at least DUNITER_NODE_NAME in env file
sudo vim /etc/duniter/env_file
# start the service
sudo systemctl start duniter-mirror.service
# follow the logs to see synchronization in progress
sudo journalctl -u duniter-mirror.service -f
# enable service if you want it to start automatically on system startup
sudo systemctl enable duniter-mirror.service

If you need help, support is available on the forum (currently french only https://forum.duniter.org/t/paquet-debian-pour-duniter/12327).

After that, you will be able to use your mirror locally (with gcli or polkadotjs), but for remote use, you will need to expose your node publicly with https, see below.

Yunohost🔗

A Yunohost package is currently available in test stage.

# install it with
yunohost app install https://git.duniter.org/bgallois/duniter-v2s_ynh

For questions, ask on the forum https://forum.duniter.org/t/paquet-yunohost-pour-duniter/12326.

Other methods🔗

Contributions are welcome for other package like:

archlinux
nix
fedora
alpine
...

Expose the RPC API publicly🔗

Once you are happy with your node, you can expose publicly its RPC API using a nginx reverse proxy for example:

server {
  server_name DOMAIN;

  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  ssl_certificate /etc/nginx/ssl/DOMAIN.cert;
  ssl_certificate_key /etc/nginx/ssl/DOMAIN.key;

  root /nowhere;

  add_header X-Frame-Options SAMEORIGIN;
  add_header X-XSS-Protection "1; mode=block";
  proxy_redirect off;
  proxy_buffering off;
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header X-Forwarded-Port $server_port;
  proxy_read_timeout 90;

  location / {
    proxy_pass http://localhost:9944;

    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;

    proxy_read_timeout 1200s;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $host;
  }
}

with the appropriate certificates. See duniter doc examples for detail.
