configure-reverse-proxy
About
This skill configures reverse proxies using Nginx, Traefik, and ShinyProxy for routing multiple services through a single entry point. It handles WebSocket proxying, path/host-based routing, SSL termination, and Docker label auto-discovery. Use it when you need to proxy WebSocket connections, automatically discover Docker services, or add SSL termination to non-TLS services.

設反代
以 Nginx、Traefik、ShinyProxy 設路流於後服之反代式。
用時
- 路多服於單入
- 代 WebSocket 連(Shiny、Socket.IO、即載)
- 以 Traefik 標自發 Docker 服
- 徑或主之路於異後
- 加 SSL 終於不治 TLS 之服
入
- 必:代之後服(host:port)
- 必:路之策(徑、主、或二)
- 可選:代具之好(Nginx、Traefik)
- 可選:主路之域名
- 可選:代之 WebSocket 端
法
第一步:擇代具
| Feature | Nginx | Traefik |
|---|---|---|
| Configuration | Static files | Docker labels / dynamic |
| Auto-discovery | No (manual) | Yes (Docker provider) |
| Let's Encrypt | Via certbot | Built-in ACME |
| Dashboard | No (3rd party) | Built-in |
| WebSocket | Manual config | Automatic |
| Best for | Static config, high traffic | Dynamic Docker environments |
第二步:Nginx——徑路
server {
listen 80;
location /api/ {
proxy_pass http://api:8000/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location /app/ {
proxy_pass http://webapp:3000/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location / {
root /usr/share/nginx/html;
try_files $uri $uri/ /index.html;
}
}
注: proxy_pass 之尾 / 剝位前綴。location /api/ 附 proxy_pass http://api:8000/; 將 /api/users 轉為 /users。
第三步:Nginx——主路
server {
listen 80;
server_name api.example.com;
location / {
proxy_pass http://api:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
server {
listen 80;
server_name app.example.com;
location / {
proxy_pass http://webapp:3000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
}
第四步:Nginx——WebSocket 代
WebSocket 需升頭。於 Shiny、Socket.IO、即載為要:
location /ws/ {
proxy_pass http://app:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_read_timeout 86400;
}
專於 Shiny 應:
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server {
location / {
proxy_pass http://shiny:3838;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_set_header Host $host;
proxy_read_timeout 86400;
proxy_buffering off;
}
}
得: WebSocket 連立且持。
敗則: 察 proxy_http_version 1.1 已設。驗 Upgrade 與 Connection 頭。
第五步:Traefik——Docker 標自發
docker-compose.yml:
services:
traefik:
image: traefik:v3.2
command:
- "--providers.docker=true"
- "--providers.docker.exposedbydefault=false"
- "--entrypoints.web.address=:80"
- "--entrypoints.websecure.address=:443"
- "[email protected]"
- "--certificatesresolvers.letsencrypt.acme.storage=/letsencrypt/acme.json"
- "--certificatesresolvers.letsencrypt.acme.httpchallenge.entrypoint=web"
ports:
- "80:80"
- "443:443"
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
- letsencrypt:/letsencrypt
api:
image: myapi:latest
labels:
- "traefik.enable=true"
- "traefik.http.routers.api.rule=Host(`api.example.com`)"
- "traefik.http.routers.api.entrypoints=websecure"
- "traefik.http.routers.api.tls.certresolver=letsencrypt"
- "traefik.http.services.api.loadbalancer.server.port=8000"
webapp:
image: myapp:latest
labels:
- "traefik.enable=true"
- "traefik.http.routers.webapp.rule=Host(`app.example.com`)"
- "traefik.http.routers.webapp.entrypoints=websecure"
- "traefik.http.routers.webapp.tls.certresolver=letsencrypt"
- "traefik.http.services.webapp.loadbalancer.server.port=3000"
volumes:
letsencrypt:
得: Traefik 以標自發服,供 SSL 證。
第六步:Traefik——徑路以標
services:
api:
labels:
- "traefik.enable=true"
- "traefik.http.routers.api.rule=Host(`example.com`) && PathPrefix(`/api`)"
- "traefik.http.routers.api.middlewares=strip-api"
- "traefik.http.middlewares.strip-api.stripprefix.prefixes=/api"
- "traefik.http.services.api.loadbalancer.server.port=8000"
第七步:Traefik——率限與頭
labels:
- "traefik.http.middlewares.ratelimit.ratelimit.average=100"
- "traefik.http.middlewares.ratelimit.ratelimit.burst=50"
- "traefik.http.middlewares.security.headers.stsSeconds=63072000"
- "traefik.http.middlewares.security.headers.contentTypeNosniff=true"
- "traefik.http.middlewares.security.headers.frameDeny=true"
- "traefik.http.routers.app.middlewares=ratelimit,security"
第八步:驗代設
# Nginx: test config
docker compose exec nginx nginx -t
# Check routing
curl -H "Host: api.example.com" http://localhost/health
# Check WebSocket (needs wscat: npm install -g wscat)
wscat -c ws://localhost/ws/
# Traefik dashboard (if enabled)
# http://localhost:8080/dashboard/
得: 請依徑或主路於正後。WebSocket 升成。
驗
- HTTP 請依徑或主路於正後
- WebSocket 連立且持
- SSL 終行(若設)
- 後受正
Host、X-Real-IP、X-Forwarded-For頭 - Traefik 以標自發新服(若用 Traefik)
- 設於
docker compose restart後存
陷
- 尾
/不合:Nginx 中proxy_pass http://app/對http://app於徑剝行異。 - WebSocket 超時:默
proxy_read_timeout六十秒。長 WebSocket 連需86400(二十四時)。 - Docker 符安:於 Traefik 掛
/var/run/docker.sock予其全 Docker 訪。用ro掛且慎思符代。 - DNS 解:Nginx 於啟時解上。動服用
resolver 127.0.0.11為 Docker 內 DNS。 - 缺
proxy_buffering off:Shiny 與 SSE 端需proxy_buffering off為實時流。
