Modify fluentd json output

Question

How can we easily transform with fluentd( and plugins ) something like this

{
    "remote": "87.85.14.126",
    "city": "saint-hubert"
}

To this:

{
   "geoip": {
       "remote": "87.85.14.126",
       "city": "saint-hubert"
   }
}

Thank you

A Fluentd maintainer here. Right now, this is kind of hard to do. But I am trying to work with upstream to make it possible in record_transformer (docs.fluentd.org/articles/filter_record_transformer). Stay tuned. — Kiyoto Tamura, Dec 18 '14 at 01:09
Oops. that was meant to be docs.fluentd.org/v0.12/articles/filter_record_transformer — Kiyoto Tamura, Dec 23 '14 at 22:46

Based on the answer by repeatedly(https://github.com/repeatedly).

<filter test.**>
  @type record_transformer
  enable_ruby true
  auto_typecast true

  <record>
    geoip ${{"remote" => "${remote}", "city" => "${city}"}}
  </record>
</filter>
