Hello,
I'm trying to run ELK for the first time inside a docker-container using the image sebp/elk and it seems to be failing to start with a clean installation on logstash in particular.
These are the startup logs:
elk | ==> /var/log/logstash/logstash-plain.log <==

elk | [2020-02-22T10:04:18,045][INFO ][logstash.runner ] Logstash shut down.
Any idea what am I missing?
