Description
This role provisions a Nimbus installation that can act as an ETH2 network bootstrap node.
Introduction
The role will checkout a branch from the nimbus-eth2 repo, build and run it.
Each host can run multiple beacon nodes. Each node can be built from a different branch (stable, unstable, testing, etc.) and will be run with systemd.
A timer is installed that will periodically pull changes from git and rebuild the binaries.
Ports
The service exposes three ports by default:
9000- LibP2P peering port. Must ALWAYS be public.9200- JSON RPC port. Must NEVER be public.9900- Prometheus metrics port. Should not be public.
Installation
Add to your requirements.yml file:
- name: infra-role-beacon-node-linux
src: git+git@github.com:status-im/infra-role-beacon-node-linux.git
scm: git
Configuration
The crucial settings are:
# branch which should be built
beacon_node_repo_branch: 'stable'
# ethereum network to connect to
beacon_node_network: 'mainnet'
# optional setting for debug mode
beacon_node_log_level: 'DEBUG'
# Infura WebSocket URLs
beacon_node_web3_urls: ['wss://mainnet.infura.io/ws/v3/123qwe123qwe123qwe']
The order of WebSocket URLs matters. First is the default, the rest are fallbacks.
Usage
Assuming the stable branch was built you can manage the service with:
systemctl start beacon-node-mainnet-stable
systemctl status beacon-node-mainnet-stable
systemctl stop beacon-node-mainnet-stable
You can view logs under:
tail -f /data/beacon-node-mainnet-stable/logs/service.log
The service will store all data in the /data/beacon-node-mainnet-stable directory.
Building
A timer will be installed to build the image:
systemctl list-timers build-beacon-node-mainnet-stable
To rebuild the image:
systemctl start build-beacon-node-mainnet-stable.service
To check build logs use:
journalctl -u build-beacon-node-mainnet-stable.service
Requirements
Due to being part of Status infra this role assumes availability of certain things:
- The
