Eth2 clients packaged for networking tests
A process runner in python for Eth 2.0 clients. Designed for use with stethoscope.
For both simulation and testing, it's valuable to be able to programmatically start and stop each Eth 2.0 client. This repo provides a python interface for doing just that.
To be platform independent, clients are run via Docker.
pip install stethoscope-clients
The key methods in this library are
connect_rumor. See below for a full sample usage:
import trio from pyrum import SubprocessConn, Rumor from sclients import start_instance, stop_instance, connect_rumor, InstanceConfig, ENR enr_str = ... client_config = InstanceConfig( client='lighthouse', beacon_state_path='./genesis.ssz', enr= ENR( private_key=..., tcp=9001, udp=9002, id='v4' ip: '127.0.0.1' enr: enr_str, attnets: ... eth2: ... ) ) try: start_instance(client_config) # This block will eventually be encapsulated in `connect_rumor` async with SubprocessConn(cmd='rumor bare') as conn: async with trio.open_nursery() as nursery: rumor = Rumor(conn, nursery) client_peer_id = await connect_rumor(rumor, enr_str) # Insert your rumor interactions with client_peer_id nursery.cancel_scope.cancel() finally: stop_instance('lighthouse')
