# See: http://kubernetes.io/docs/user-guide/labels/#list-and-watch-filtering
# labelselector = "A and not B"
# Ingress label selector to identify Ingress objects that should be processed.
# See https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors for details.

# Optional
# Default: empty (process all Ingresses)

Annotations can be used on containers to override default behaviour for the whole Ingress resource:

## Forwarding to ExternalNames
When specifying an [ExternalName](https://kubernetes.io/docs/concepts/services-networking/service/#services-without-selectors),
Træfik will forward requests to the given host accordingly and use HTTPS when the Service port matches 443. This still requires setting up a proper port mapping on the Service from the Ingress port to the (external) Service port.
## Disable passing the Host header
By default Træfik will pass the incoming Host header on to the upstream resource.
