如何在ansible-playbook中设置2环境（PATH和proxy_env）？

Question

How correct write task ?

- name: Install required python modules
  pip:
    name: "{{ item }}"
    extra_args: "{{ pip_extra_args | default(omit) }}"
  with_items: "{{pip_python_coreos_modules}}"
  environment:
    PATH: "some path"
  environment: "{{ proxy_env }}"

How set 2 environment (PATH and proxy_env ) ? Thanks

Ansible makes it easy for you to configure your environment by using the 'environment' keyword. Here is an example:

- hosts: all
  remote_user: root
  tasks:
  - apt: name=cobbler state=installed
    environment:
       http_proxy: http://proxy.example.com:8080

The environment can also be stored in a variable, and accessed like so:

- hosts: all
  remote_user: root
  # here we make a variable named "proxy_env" that is a dictionary
  vars:
    proxy_env:
       http_proxy: http://proxy.example.com:8080
  tasks:
  - apt: name=cobbler state=installed
    environment: "{{proxy_env}}"
