# Demo: create N Managed proxies backed by the kubernetes-pod provider,
# named proxy-kubernetes-demo-1 .. proxy-kubernetes-demo-N. Pods share the
# cluster's egress IP — this exercises the full lifecycle, not distinct
# egress paths (use create-gcp-proxies.sh for that).
#
# Usage:
#   ./create-kubernetes-proxies.sh <count>
#
# Optional environment:
#   NAMESPACE  namespace to create the proxies in (default: current context)
