Hello Team,

Could you please help me understand is there an option to keep configuration variables outside of pipeline.  
for example if i have 4 pipeline with elasticsearch as input and output for this most of the configuration would be same and making changes to this would also be very easy . so can i keep few variables in file like hosts , keystore etc in a config file and read it from there.

Thanks for your help and support.

Thank you,  
Aditya

You can reference [environment variables](https://www.elastic.co/guide/en/logstash/current/environment-variables.html) in the configuration (but [not](https://github.com/elastic/logstash/issues/5115) in conditionals). logstash also supports the use of a [keystore](https://www.elastic.co/guide/en/logstash/current/keystore.html) for passwords and keys, which are hopefully environment specific.
