Description

This role provisions a Nimbus installation that can act as an ETH2 network bootstrap node.

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.

Configuration

Minimum configuration would include.

beacon_node_network: 'testnet0'
# Infura Web Sockets URLs
beacon_node_web3_urls: ['wss://mainnet.infura.io/ws/v3/123qwe123qwe123qwe']

The order of Web Socket URLs matters. First is the default, the rest are fallbacks.

It might be useful to increase the log verbosity level:

beacon_node_log_level: DEBUG

Management

The containers are managed using WinSW.

TODO

The logs for scheduled tasks running builds can be looked up using Get-WinEvent:

PS C:\Users\nimbus\beacon-node-prater-stable> Get-WinEvent -LogName Microsoft-Windows-TaskScheduler/Operational | Select -First 4 | ft -Property TimeCreated,Message
