Can not access environment variables via lookup module

[Kei Yamazaki]

I executed following playbook that uses lookup module and the "environment" settings.
But can not access environment variables.

How can I access environment variables?

- hosts: all
  user: root

  vars:
    env:
       http_proxy: http://proxy.example.com:8080

  tasks:

    - shell: "echo {{ lookup('env', 'http_proxy') }}"
      environment: env

Output with trace logs.

soo, lookups occur on master, environment sets the execution for the
target machine. you are querying diff machine than you are setting.
