Is a traefik config with both docker swarm and consul backend possible? - docker

Question

Are the consul and docker swarm configuration backends compatible?
My requirement is that I need to start N traefik containers as a docker service, where they get their dynamic frontends/backends via docker swarm but I also need all N of the traefik containers to use a shared ACME config (i.e. sourced from consul).
I'd like it so that Frontends/backends info should come from the docker swarm, while the ACME config should come from consul. As far as any other static traefik configs, i'm fine if it comes from a static file, but this really won't work for the ACME.json as a file via a volumne because how would locks for writes be managed? The only option I see is the consul KV store for that.
The issue i see is that this kind of setup is not possible?

Uploaded my TOML config into consul KV which looks like this: (stored under "traefik-stage" root in consul KV)

sans = ["myapp2-stage.my-domain.com"]
Started traefik with:
docker service create \
--name traefik \
--constraint=node.role==manager \
--publish 80:80 \
--publish 8080:8080 \
--publish 443:443 \
--mount type=bind,source=/var/run/docker.sock,target=/var/run/docker.sock \
--network my-net \
-e "CONSUL_HTTP_TOKEN=xxxxxx" \
traefik \
--consul \
--consul.endpoint=my-consul.my-domain.com:8500 \
--consul.watch=true \
--consul.prefix="traefik-stage"
NOTE! tried both with and without the docker flags in either consul or as command line flags to no avail:
--docker \
--docker.swarmmode \
--docker.domain=traefik \
--docker.watch
Next started my N other docker services that I want traefik to proxy, each started w/ the relevant flags as such
...
--publish :9000
--label traefik.protocol=https
--label traefik.port=9000
--label traefik.frontend.rule='Host:myapp1.my-domain.com,myapp1-stage.my-domain.com'
--label traefik.docker.network=my-net
--network my-net
...
Note this above setup (with traefik config fully in TOML file, not in consul) works fine
What I you expect to see?
When I go to http://localhost:8080/dashboard/#/ I see my 2 frontends/backends appropriately discovered via traefik and setup properly as they work w/out consul
What did I see instead?
Nothing in the UI, however the logs show evidence that traefik is indeed getting the frontend/backend info from docker and wiring it up. But nothing shows in the UI nor does any of the actual routing work for those hosts.
