hacky script to bootstrap test nodes for parity test net

qp.dev-net

#!/bin/sh

# hacky but useable script for quick/easy parity test node deployment. Requires commands "parity" and "tmux"

# Set these as required:

BASE_PATH=~/meth/nodes
BIND_IP=10.45.92.1
LOG_LEVEL=info

# BIND_IP for example can be an openvpn tun0 interface's IP (exactly why I do this).

#   ---
# example... create three peers:
#   qp.dev-net peer0
#   qp.dev-net peer1
#   PORT=30303 WS_PORT=8546 JSONRPC_PORT=8545 UI_PORT=8180 qp.dev-net master
#
# after doing this, you must append all three nodes' "enode://" URIs to "$HOME/reserved-peers"
# (and SIGHUP...? do nothing? I've just been restarting peers)
