Control experiment isolates two independent causes: the nginx 443 block still emits X-Forwarded-Proto http, and Traefik rewrites forwarded headers regardless. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

=== [1] 호스트 nginx 가 주입하는 헤더 ===
|
|
3: server 192.168.122.11:80;
|
|
4: server 192.168.122.12:80;
|
|
8: listen 80 default_server;
|
|
14: listen 443 ssl default_server;
|
|
26: proxy_set_header Host $host;
|
|
27: proxy_set_header X-Forwarded-Host $host;
|
|
28: proxy_set_header X-Forwarded-Proto http;
|
|
29: proxy_set_header X-Forwarded-Port 80;
|
|
30: proxy_set_header X-Forwarded-For $remote_addr;
|
|
31: proxy_set_header X-Real-IP $remote_addr;
|
|
|
|
=== [2] Traefik entryPoint 인자 (forwardedHeaders 부재 확인) ===
|
|
["--entryPoints.metrics.address=:9100/tcp"
|
|
"--entryPoints.traefik.address=:8080/tcp"
|
|
"--entryPoints.web.address=:8000/tcp"
|
|
"--entryPoints.websecure.address=:8443/tcp"
|
|
"--metrics.prometheus.entrypoint=metrics"
|
|
"--entryPoints.websecure.http.tls=true"
|
|
→ forwardedHeaders.trustedIPs 인자가 없음 = 기본값(신뢰 안 함)
|
|
|
|
=== [3] Traefik 파드 수와 위치 ===
|
|
traefik-59b7647586-ftwf8 10.42.0.8 kc-lab-1
|
|
|
|
=== [4] traefik Service externalTrafficPolicy ===
|
|
Cluster
|
|
→ Cluster = svclb 가 SNAT 하여 클라이언트 IP 소실
|
|
|
|
=== [5] 앱 파드의 스위치 상태 ===
|
|
SERVER_PORT=8081
|

SERVER_FORWARD_HEADERS_STRATEGY=none
