Overriding toml configuration with environment variables

[jmahowald]

volume mounts for the toml files can be difficult in a cluster. Rancher or swarm for instance. Yes, one can setup volume drivers, but that is a non-trivial setup.

Please consider using something like viper or goconfig to allow you to easily allow environment variables to override. For instance, in my case, I'd love to be able to have an env variable like

-e TRAEFIK_CONSULCATALOG_ENDPOINT=$CONSUL_ADDR

In the meantime, I have a dockerfile that extends yours adds in the toml, and allows changes via dockerize

Hi, you can override every parameters using arguments.

Great. I was going to ask the convention, but I see them all in --help now.
For anyone else who comes across this thread, the setting I'd want would be
--consulcatalog.endpoint Consul server endpoint (default "127.0.0.1:8500")
