Docker Swarm Mode Network Filter Change Issue

[danieladams456]

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

Bug

What did you do?

Deployed a Docker Swarm service of Traefik

What did you expect to see?

Services to come be discovered and show on the web UI like they did in 1.4.0-rc5-alpine.

What did you see instead?

The web UI is blank. It is not able to enumerate the networks/containers. Logs are posted down below.

Looking at the changelog, it seems like the error is related to #2244

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

Version:      v1.4.0
Codename:     roquefort
Go version:   go1.9.1
Built:        2017-10-16_04:52:07PM
OS/Arch:      linux/amd64

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

I am using a docker compose stack and specifying the configuration all in the command via a template that is rendered with environment variables at deploy time.

    command:
      - --web
      - --logLevel=DEBUG
      - --accessLog
      - --accessLog.format=json
      - --entryPoints=Name:https Address::443 TLS:/run/secrets/traefik-cert,/run/secrets/traefik-key
      - --defaultEntryPoints=https
      - --docker
      - --docker.swarmmode
      - --docker.watch
      - --docker.domain=redacted.net
      - --forwardingTimeouts.dialTimeout=10s
      - --forwardingTimeouts.responseHeaderTimeout=60s

If applicable, please paste the log output in debug mode (--debug switch)

I was not able to reproduce on my 17.09.0-ce laptop, but https://github.com/pistolero/traefik/blob/master/provider/docker/docker.go#L35 says the API version is locked at 1.24 and the docker host is at 1.27, so it should be new enough.

Sorry I answered my own question: Docker EE only added support in version 17.06

https://docs.docker.com/enterprise/17.06/

Add --filter scope=<swarm|local> to docker network ls #31529

I know it's a good bit of cross-referencing with all the backends, and maybe I missed it, but it would be nice if there was a section of the docs that listed out the minimum requirements so people can know when they can expect a feature to work.
