# ErrorPage
|
|
|
|
It Has Never Been Easier to Say That Something Went Wrong
|

|
|
|
The ErrorPage middleware returns a custom page in lieu of the default, according to configured ranges of HTTP Status codes.
|
|
|
|
!!! important
|
|
The error page itself is _not_ hosted by Traefik.
|
|
|
|
## Configuration Examples
|
|
|
|
```yaml tab="Docker"
|
|
# Dynamic Custom Error Page for 5XX Status Code
|
|
labels:
|
|
- "traefik.http.middlewares.test-errorpage.errors.status=500-599"
|
|
- "traefik.http.middlewares.test-errorpage.errors.service=serviceError"
|
|
- "traefik.http.middlewares.test-errorpage.errors.query=/{status}.html"
|
|
```

|

|
|
!!! note ""
|
|
In this example, the error page URL is based on the status code (`query=/{status}.html`).
|
|
|
|
## Configuration Options
|
|
|
|
### `status`
|
|
|
|
The `status` that will trigger the error page.
|
|
|
|
The status code ranges are inclusive (`500-599` will trigger with every code between `500` and `599`, `500` and `599` included).
|
|
|
|
!!! note ""
|
|
|
|
You can define either a status code like `500` or ranges with a syntax like `500-599`.
|
|
|
|
### `service`
|
|
|
|
The service that will serve the new requested error page.
|
|
|
|
!!! note ""
|
|
In kubernetes, you need to reference a kubernetes service instead of a traefik service.
|
|
|
|
### `query`
|
|
|
|
The URL for the error page (hosted by `service`). You can use `{status}` in the query, that will be replaced by the received status code.
