Hi Team,
Created a Pod for logstash and I am trying to solve the below error. Requesting your help for the same.
```auto

logstash is configured with http plugin.

I have resolved that error and the logstash pod, fails to run because of GemSpecError. Hoping for some more guidance.

Does it try to require a relative path? That's been removed in Ruby 1.9. Bundler cannot continue.
