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 driver: opens a tmux session with a 2x2 pane grid:
|
|
#
|
|
# top-left: show-egress-ips-table.sh in a 10s loop, run inside the
|
|
# netshoot pod against the in-cluster discovery Service
|
|
# top-right: watch -n3 kubectl get px
|
|
# bottom-left: create-kubernetes-proxies.sh <count>
|
|
# bottom-right: create-gcp-proxies.sh <count>
|
|
#
|
|
# Usage:
|
|
# ./run-demo.sh
|
|
#
|
|
# Optional environment:
|
|
# COUNT proxies each create script makes (default: 4)
|
|
# SESSION tmux session name (default: proxy-demo; an existing
|
|
# session with this name is killed and recreated)
|
|
# NETSHOOT_POD pod to exec into for the egress-IP loop (default: netshoot)
|
|
# DEMO_DIR where the demo scripts live (default: this script's dir)
