# Example
|
||||
## Adding a custom ban page
|
||||
|
||||
Traefik can return a custom HTML ban page along with the 403 HTTP response code.
|
||||
This can be usefull as some browser (Firefox for instance) return a 403 blank webpage and we can mistake a server/reverse-proxy error with a ban from Crowdsec.
|
||||
|
||||
### Traefik configuration
|
||||
|
||||
|
||||
```yaml
|
||||
labels:
|
||||
# Define ban HTML file path
|
||||
- "traefik.http.middlewares.crowdsec.plugin.bouncer.banHtmlFilePath=/ban.html"
|
||||
```
|
||||
|
||||
The ban HTML file must be present in the Traefik container (bind mounted or added during a custom build).
|
||||
It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/ban.html) it locally to expose it to Traefik.
|
||||
|
||||
```yaml
|
||||
...
|
||||
traefik:
|
||||
image: "traefik:v2.11.0"
|
||||
volumes:
|
||||
- './ban.html:/ban.html'
|
||||
...
|
||||
```
|
||||
|
||||
## Exemple navigation
|
||||
|
||||
We can try to query normally the whoami server:
|
||||
```bash
|
||||
curl http://localhost:8000/foo
|
||||
```
|
||||
|
||||
We can try to ban ourself
|
||||
|
||||
```bash
|
||||
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type ban
|
||||
```
|
||||
|
||||
|
||||
We will see in the browser the ban custom page:
|
||||
|
||||
To play the demo environment run:
|
||||
```bash
|
||||
make run_custom_ban_page
|
||||
```
