ErrorPage

It Has Never Been Easier to Say That Something Went Wrong

ErrorPages

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

# 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"
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: test-errorpage
spec:
  errors:
    status:
      - 500-599
    query: /{status}.html
    service:
      name: whoami
      port: 80

# Custom Error Page for 5XX
[http.middlewares]
  [http.middlewares.test-errorpage.errors]
    status = ["500-599"]
    service = "serviceError"
    query = "/{status}.html"

[http.services]
  # ... definition of error-handler-service and my-service
# Custom Error Page for 5XX

  middlewares:
    test-errorpage:
      errors:
        status:
          - "500-599"
        service: serviceError
        query: "/{status}.html"

[http.services]
  # ... definition of error-handler-service and my-service

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).

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.

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.
