So finally figured out the issue. After comparing the docker-compose file with a 'Hello World' application I realised that the 'image' tag in the docker-compose was causing the 'invalid reference format' error.

For example in the definition of the 'basket' microservice the 'image' has the following value.
basket.api:
image: eshop/basket.api:${TAG:-latest}

If I remove ':${TAG:-latest}' everything runs as expected. Not sure what the problem with the value is though. Still not that docker proficient. I removed this tagging for all service entries.

@audipen The issue with the ${TAG:-latest} was a bug in the VS Docker tools. It's fixed in the VS 2017 15.4 update (currently in preview).

 

解決方案：

刪除docker-compose.yml中所有鏡像的 ':${TAG:-latest}' 后綴。因為默認debug模式下，visual studio 2017 docker tools會生成docker-compose.vs.debug.g.yaml，會在鏡像后增加:dev標簽。如果在docker-compose.yaml中增加了latest標簽，則會導致生成的鏡像為name:latest:dev，導致編排失敗。

這是visual studio 2017 docker tool的bug，會在后續版本解決。

當前的解決方案是，刪除所有':${TAG:-latest}' 后綴。
