-# Traefik Edge Stack
+# GB Traefik Setup
 
-Reverse proxy for everything on this host. The goal: keep Cloudflare in front, expose a private LAN entrypoint, and let Docker stacks self-register through labels without leaking secrets.
+This repository contains the configuration files and setup instructions for deploying [Traefik](https://traefik.io/), a modern reverse proxy and load balancer.
 
-## Architecture Snapshot
+Configuration files is customized for Gbanyan personal usage. 
 
-- **Static config (`traefik.yml`)**  
-  - EntryPoints: `web/websecure` on `10.0.0.225`, `internal_web/internal_websecure` on `192.168.50.4`.  
-  - Trusted IP lists are managed by `scripts/update_cloudflare_ips.py`.  
-  - Docker provider is discovery-only; every container opts in with labels.  
-  - File provider loads everything in `dynamic.d/`.
+## Prerequisites
 
-- **Dynamic config (`dynamic.d/`)**  
-  - `middlewares/` – retry, compression, CrowdSec (rendered from template).  
-  - `transports/fast-upstreams.yml` – shared connection pool tuning.  
-  - `routers/` – internal-only routers (public ones stay in labels).
+- Docker installed on your system
+- Docker Compose (if using `docker-compose.yml`)
 
-- **Host networking**  
-  Traefik runs with `network_mode: host` so it can bind to both IPs simultaneously. Switching to bridge mode would require duplicating Traefik or adding another L4 hop, so host mode stays.
+## Getting Started
 
-## Secrets Workflow
+1. Clone this repository:
+    ```bash
+    git clone https://gitea.gbanyan.net/gbanyan/GB-Traefik.git
+    cd GB-Traefik
+    ```
 
-1. Copy `.env.example` → `.env` and fill:
-   - `CLOUDFLARE_EMAIL`, `CLOUDFLARE_DNS_API_TOKEN`
-   - `CROWDSEC_LAPI_KEY`
-2. Render secret-aware dynamic files:
-   ```bash
-   ./scripts/render_dynamic.sh
-   ```
-   This uses `templates/crowdsec.yml.tmpl` and writes `dynamic.d/middlewares/crowdsec.yml` (ignored by git).
+2. Update the `traefik.yml` and `docker-compose.yml` files as needed for your environment.
 
-## Runbook
+3. Start Traefik:
+    ```bash
+    docker compose up -d
+    ```
 
-```bash
-# start / update Traefik
-docker compose up -d traefik
+4. Access the Traefik dashboard (if enabled) at `http://<your-domain-or-ip>:8080`.
 
-# refresh Cloudflare IPs and restart safely
-python scripts/update_cloudflare_ips.py
+## Configuration
 
-# tail logs
-tail -f traefik.log
-tail -f access.log
+- **.env**: Cloudflare E-mail and API Token for SSL DNS Challenge
+- **Traefik Configuration**: Modify `traefik.yml`, `dynamic.yml` to customize Traefik's behavior.
+- **Docker Compose**: Use `docker-compose.yml` to define services and networks.
+
+
+## Detail: 
+
+My traefik is split into internal and external entrypoint. 
+
+Internal entrypoint is for private and secure service without exposing. 
+
+Each entrypoint is binded to different ip address for isolation. 
+
+Then, other docker service is attached to different entrypoint guided by label in docker compose
+
+```yaml
+label: 
+    - "traefik.http.routers.service-name.entrypoints=websecure"
 ```
 
-Rotate CrowdSec keys? Edit `.env`, rerun `render_dynamic.sh`, then `docker compose up -d traefik`.
+Besides the entrypoint setup, I add cloudflare proxy (for exposing real ip to access.log for crowdsec to read), crowdsec-firewall-bouncer, compression with brotli middlrewares method in traefik.yml and dynamic.yml
 
-## Service Labels Cheat Sheet
+Adding middlewares is also guided by labels: 
+
+```yaml
+label: 
+    - "traefik.http.routers.service-name.middlewares=cloudflarewarp@file,crowdsec@file,compress-middleware@file"
+```
+
+The order of middlewares is meaningful. 
+
+Traefik has ability to apply SSL certs automatically. 
+Just offer the required DNS API authentication (Like cloudflare). 
+
+Please refer the traefik documentation. 
+
+The following is an example of a docker service I hosted in its docker-compose.yaml: 
 
 ```yaml
 labels:
-  - traefik.enable=true
-  - traefik.http.routers.myapp.rule=Host(`app.example.com`)
-  - traefik.http.routers.myapp.entrypoints=websecure
-  - traefik.http.routers.myapp.tls.certresolver=letsencrypt
-  - traefik.http.routers.myapp.middlewares=crowdsec@file,retry-fast@file,compress-middleware@file
-  - traefik.http.services.myapp.loadbalancer.serversTransport=fast-upstreams@file
-  - traefik.http.services.myapp.loadbalancer.server.port=3000
-  - traefik.docker.network=traefik_default
+      - "traefik.enable=true"
+      - "traefik.http.routers.ghost.entrypoints=websecure"
+      - "traefik.http.routers.ghost.rule=Host(`blog.gbanyan.net`)"
+      - "traefik.http.services.ghost.loadbalancer.server.port=2368"
+      - "traefik.http.routers.ghost.tls.certresolver=letsencrypt"
+      - "traefik.http.routers.ghost.middlewares=cloudflarewarp@file,crowdsec@file,compress-middleware@file"
+      - "com.centurylinklabs.watchtower.enable=true"
+      - "traefik.docker.network=traefik_default"
 ```
 
-Most stacks use the same middleware chain: CrowdSec bouncer (plugin), retry, and compression. Internal-only services skip CrowdSec by pointing at the `internal_*` entrypoints.
+I mount the access.log for crowdsec firewall to read. 
 
-## Performance Notes
+PS: Because I access my traefik dashboard through my local network. I commented out the authetication method for dashboard. 
 
-- Access logs are buffered with headers trimmed to keep syscalls down.  
-- Compression enforces a 1 KB minimum and respects the client’s preferred encoding.  
-- Shared transport keeps 64 idle connections per backend with aggressive idle/response timeouts.  
-- `retry-fast` retries once after 50 ms, smoothing transient Puma/Node hiccups without hammering backends.
+## Discussion and Changelog
 
-## Things to Remember
+1. Traefik vs Nginx
+- Performance: Nginx is still better at high traffic. After all it is written in C. Traefik 3 though claims it has higher 20% performance than before. The latency still showed a little higher than nginx. 
+- Docker Deployment Ease: Traefik is easier for docker service deployment. In my environment, I can assign each docker stack with labels and then guides the traefik to add Let's encrypt SSL. 
 
-- Watchtower is still enabled for Traefik; pin the image tag when you need deterministic upgrades.  
-- `scripts/update_cloudflare_ips.py` rewrites the static trusted IP block and restarts Traefik—run it via cron.  
-- Dashboard auth is intentionally disabled because access only happens from the LAN entrypoint. If that changes, re-enable `basicauth`.
+2. ChangeLog: 
+
+- 2025.4.18 Add Souin HTTP Cache Middleware.
