Am trying to write a dockerfile that sets up logstash aswell as a logstash output plugin for AWS S3.  
This: [https://rubygems.org/gems/logstash-output-s3](https://rubygems.org/gems/logstash-output-s3)  
However i keep getting errors, and ive tried other gems too where its the same problem that i cant find them. I tested my internet and its fine, i can even update GEM without issue, yet cant get any gems downloaded.  
I check my sources list and it holds [https://rubygems.org](https://rubygems.org) so it should be fine as is.

Anyone who knows this issue or what the problem could be?

Ha... Ha... Jokes on me, this plugin is part of the default Logstash applikation. Problem solved.
