Sorry to have to reopen this.

Am I right? => In 0.9.1 it’s still not possible to generate the erd inside a docker build. So this issue is not resolved, is it? If you don’t want to address this issue I can also try to contribute if you tell me where to start. 😃

All the best, Thomas

I can replicate. The last version to work with docker was 0.6.1. I need to dig through the commits to see what happened in 0.7.0 to see if there is a way to make everyone’s use case work.
