run-demo.sh opens a 2x2 tmux grid: egress-IP table looping in a netshoot pod, kubectl get px watch, and both create scripts running with COUNT (default 4) proxies. show-egress-ips-table.sh is the pane-sized one-line-per-proxy variant used by the driver.

# Demo: condensed-table variant of show-egress-ips.sh, made to fit a small
|
|
# tmux pane. One line per proxy: which proxy the request goes through, its
|
|
# endpoint, location (zone/geo attribute), and the egress IP the IP-echo
|
|
# site saw — or unhealthy/FAILED.
|
|
#
|
|
# Usage:
|
|
# ./show-egress-ips-table.sh <BASE_URL> e.g. ./show-egress-ips-table.sh localhost:8090
|
|
#
|
|
# Optional environment:
|
|
# TOKEN bearer token for the discovery API (see docs/api.md)
|
|
# IP_ECHO_URL site that returns the caller's IP as JSON with an "ip" field
|
|
# (default: https://api.ipify.org?format=json)
