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.
Docker
We chose docker as the standard way to deploy a node. Distribution packages are not yet provided. First install docker on your platform. Then use the following docker-compose.yml
example file:
version: "3.5"
services:
duniter-rpc:
image: duniter/duniter-v2s:xxx # <----
restart: unless-stopped
ports:
# Prometheus endpoint
- 9615:9615
# rpc via http
- 9933:9933
# rpc via websocket
- 9944:9944
# p2p
- 30333:30333
volumes:
- data-rpc:/var/lib/duniter/
environment:
- DUNITER_CHAIN_NAME=yyy # <----
- DUNITER_NODE_NAME=zzz # <----
command:
# disable pruning for an archive node
- "--pruning=14400"
volumes:
data-rpc:
Replace xxx
by the Duniter version you want to use. For example, to join gdev
development network, you can use sha-latest
version which includes embeded chainspecs.
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.
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.
