For those using traefik I would recommend the dynamic file config. You don't have to take down your containers just to change a proxy setting.
With labels you just update the service definition by redeploying the stack; the dynamic file provider adds nothing in most circumstances.
You certainly don't need to take down your container except to change things that are part of the Traefik static configuration.
That's the point. With dynamic files you can add new Middleware or even route already exposed ports all on the fly. You're telling me you can change a docker label and keep your service running with 0 downtime?
If you've figured that out please share a link because my experience has been otherwise.
Close enough to 0 downtime that it doesn't matter.
Seriously, you shouldn't need to put anything (outside of rules that you want to re-use [e.g. http->https middleware]) in the traefik dynamic configuration because each container/service in a docker stack will bring with it its own configuration. Your only 'dead time' is how long it takes Traefik to pick up the new dynamic configuration via either the
dockerorswarmproviders, which is configurable but I've never had to touch because, even on production systems, it's been fine.
