Rancher-compose example please

The docs say "First is to set build: to a git or HTTP URL " but after reading the provided link I’m still confused.
I have a local docker-compose.yml that builds several Dockerfiles each in it’s own sub-directory all on the local file-system, version controlled with HG ( mercurial) and deploying to a local VM running rancher-server.

What should the rancher-compose command look like please?

Look, maybe it will help you

@emailgregn I’m not sure if using git/HTTP URL would work. But you could probably upload using S3.
