Strategies for running templated configuration - Vector Aggregator Service - Linux Service

[tbenade]

Hi, wondering if there any documented or well known solutions for running templated configurations that can be migrated between environments for example test & prod. I haven't been able to get environment variables to work so assuming Im not the first person here so would love to know how others are templating their configuration and reusing it in different environments.

For example if you had a different Splunk index for each environment? Thanks
