# bootstrap-peers.sh — fetch curated third-party bootstrap enodes for a network.
|
|
#
|
|
# Secondary seed source for peer-reinject / restore flows. Primary source remains
|
|
# the node's own peer-capture state. Same public JSON customers curl:
|
|
# https://stakesquid.eu/bootstrap/<network>.json
|
|
#
|
|
# Usage:
|
|
# bootstrap-peers.sh <network> # print enodes (one per line)
|
|
# bootstrap-peers.sh <network> --json # print full JSON
|
|
# bootstrap-peers.sh --from-compose <path> # derive network from compose path
|
|
# bootstrap-peers.sh ... --dry-run # show URL + count, no failure on empty
|
|
#
|
|
# Env:
|
|
# BOOTSTRAP_BASE_URL default https://stakesquid.eu/bootstrap
|
|
# BOOTSTRAP_MAX max enodes to emit (default 25)
