Problem

On start I have ERROR vector::cli: Configuration error. error=Missing environment variable in config. name = "ES_HOST"

I don't expect variables to be checked in configuration comments.

Configuration

sinks:
  es:
    inputs: ["json_parser"]
    type: "elasticsearch"
    mode: "bulk"
    acknowledgements:
      enabled: true
    bulk:
      index: "vector-{{ _vector._es_index }}-%Y.%m.%d" # https://docs.rs/chrono/0.4.19/chrono/format/strftime/index.html#specifiers
      #index = "{{ _es_index }}"
    #endpoints = "${ES_HOST}"  # указывается с протоколом и портом
    endpoints: ["http://elasticsearch:9200"]
    compression: "gzip"
