Mikael,
The port mapping might be the issue. You can change the port on the
host side, but not on the container side - the Processor is using 8080
internally. So you should be using -p 8090:8080 I think.
https://docs.docker.com/engine/reference/commandline/run/#publish-or-expose-port--p---expose
When the example runs successfully, there will be nothing on
http://localhost:8090/ because no template matches "/" - but there
will be something on http://localhost:8090/birthdays. Maybe I should
improve the example to avoid this pitfall.
Mind that Wikidata's SPARQL endpoint can fail, for some reason
unrelated to the Processor.
Stick with me, I think you're very close :)
