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 | [2020-02-22T10:04:10,425][INFO][logstash.runner] Starting Logstash {"logstash.version"=\>"7.6.0"}

elk | [2020-02-22T10:04:18,045][INFO][logstash.runner] Logstash shut down.

Any idea what am I missing?

Solved my own problem, for anyone interested it was because the configuration file was saved as UTF-8 with BOM
