Examples with Docker image: container exits immediately

[joschkabirk]

Bug description

I noticed that when running the examples as documented e.g. here (i.e. by running docker run -ti riga/law:example workflows), the container exits immediately.

I think this is due to this line in the start_example.sh, where the last command is bash -i --login.

The resulting error is then bash: --: invalid option. Maybe this should be changed to just bash --login?

You might be right! I'm going to have a look asap.
