There was a problem hiding this comment.
This is accurate for backends which are not segments. However, when we use segments, as explained in #4284, the backend name is being set as backend-<container-name>-backendsite1 where traefik.backend=backendsite1 has been specified by
the user.

What does this PR do?
This PR rephrases the definition of the label
traefik.backendin the documentation.Motivation
As underlined in #4284 and #4024, the actual definition of the label
traefik.backendleads to confusion: the provided value is expected to be the full backend name.
But it is an internal naming, which depends on dynamic name generation,
and the provided value is used as a suffix, to discriminate backends from each others.
So here is this PR, trying to rephrase to make it more close to reality, and to avoid false expectations when using the API.
