We have 3 different config files for 3 envs on the project. Each env is a separate cluster. All config files are similar to each other but the one difference - field.env, which is related to environment, accordingly.

Thats why now we have a lot of value files for each env.

How can we optimize this? Maybe somehow leave only one value file, and override it through the helm task from external variable groups? If it possible?  
Thanks

You may use [environment variables](https://www.elastic.co/guide/en/beats/filebeat/current/using-environ-vars.html) in your configuration files.

This is how I did a couple of years ago, had something like this:

```auto
fields:
    env: "${HOST_ENV}"
    dc: "${HOST_DC}"

```

Then each host running filbeat had those two environment variables, in windows hosts they where set as global environment variables and in linux hosts I had a `/etc/filebeat/env` file and a `override.conf` pointing to this file in the systemd service.
