annotation documentation for middleware incorrect

[travisghansen]

Do you want to request a feature or report a bug?

Bug

What did you do?

Try adding a middleware to an Ingress per the doc of the new feature in 2.2.

https://github.com/containous/traefik/pull/6160/files

traefik.ingress.kubernetes.io/router.middlewares: prefix@kuberntes-crd

What did you expect to see?

The middleware applied to the Ingress

What did you see instead?

Failure and a 404 on the endpoint.

Output of traefik version: (What version of Traefik are you using?)

2.2.0-rc2

What is your environment & configuration (arguments, toml, provider, platform, ...)?

Ingress mode installed via the helm chart.

Simply removing the - from the namespace aspect of the middleware works.

ie: traefik.ingress.kubernetes.io/router.middlewares: prefix@kuberntescrd

Also, it may be good to give some explanation about the autogenerated names of the middlewares created via CRD. For example explain something like:

Middlewares created via CRD take the format of `<k8s namespace>-<k8s name>@kubernetescrd`.

Hello,

could you open a PR on the branch v2.2 to fix that?

Thanks.

I'm pretty strapped for time currently. Mostly just letting you know. If I get a chance I'll see what I can do though.
