Setting the Environment (and Working With Proxies)
==================================================
.. versionadded:: 1.1
It is quite possible that you may need to get package updates through a proxy, or even get some package
updates through a proxy and access other packages not through a proxy. Or maybe a script you might wish to
call may also need certain environment variables set to run properly.
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}}"
You can also use it at a playbook level::
- hosts: testhost
roles:
- php
- nginx
environment:
http_proxy: http://proxy.example.com:8080
While just proxy settings were shown above, any number of settings can be supplied. The most logical place
to define an environment hash might be a group_vars file, like so::
---
# file: group_vars/boston
ntp_server: ntp.bos.example.com
backup: bak.bos.example.com
proxy_env:
http_proxy: http://proxy.bos.example.com:8080
https_proxy: http://proxy.bos.example.com:8080
.. note::
``environment:`` is not currently supported for Windows targets
