Tilt: no documentation for dc_resource method

[kvokka]

servantes demo project contains the line

dc_resource('fortune', image='fortune_for_dc')

But this command is not documented at https://docs.tilt.dev/api.html#api.k8s_resource

Thanks for the report!

@maiamcc do you remember what this is for and if it still works?

Oh shoot yes this thing! It's the Docker Compose equivalent of k8s_resource -- you use it to configure a Docker Compose resource, but the functionality is currently kind of limited:

• image argument is vestigial -- it used to associate an image with your DC resource, but now this is done automatically. (What it _can't_ do that it should be able to to do is override the image named in docker-compose.yml if the image you specify in dc_resource is different...)
• trigger_mode - configure how the service updates (automatically or manually)

In future, you'll be able to set things like port forwards with this function.

Great eye, @kvokka -- I'll update the docs and fix the demo app/required arg behavior sometime this week!
