No image or build context specified error when using override file

[joltcoke]

I have a docker-compose.yml (which doesn't contain a build or image setting) and a docker-compose.override.yml (which contains an image setting).

Trying to run "ecs-cli compose create" will result in the following error:

Service 'xyz' has neither an image nor a build context specified

Seems like ecs-cli is evaluating the existence of either build or image settings per file instead of merging all files before doing the check. docker-compose works just fine with the same configuration files.

Workaround: Adding a fake "build: ." setting to docker-compose.yml

@joltcoke, I reproduced your issue, and looked into where it comes from in our code. This error comes from https://github.com/docker/libcompose; which we use to parse compose files. This issue would be difficult for us to fix on our own; it would be preferable if libcompose would fix it. You may open an issue against them.

Thanks for investigating. I've filed an issue with libcompose and will keep you updated here on the progress.
