Description
Follow-up to #1064.
This updates the remaining Envoy admin URLs in
pkg/envoy/proxy.goto usenet.JoinHostPortinstead of manually formattinghost:portpairs.The previous
fmt.Sprintf("http://%s:%v/...")pattern is not safe for all admin bind addresses, especially IPv6 addresses.Drain()andQuit()were already updated to usenet.JoinHostPort; this change applies the same fix to:DumpConfig()via/config_dump?include_edsReady()via/readyThis keeps Envoy admin endpoint construction consistent across the proxy manager and avoids malformed URLs when the admin address is not a simple IPv4/hostname value.
Testing
pkg/envoy/proxy_test.go
