Problems with yaml docker setup


i try to setup a travis-ci config for my project, but without success.
My actual config is like that

I have a working setup for gitlab ci and i want to use that also on travis-ci.

I am looking forward to any help or tips on how to set this up properly.

Best regards

If you need to run some commands in Docker, you should, naturally, use docker commands like docker run for that. Likewise if you need to save some output outside of the container – you can e.g. use Docker mounts.

Thank you for your help
