# it is often useful to be able to set the environment for one command and have that environment be totally
# different for another. An example is you might use a HTTP proxy for some packages but not for others.
#
# in Ansible 1.1 and later, you can pass the environment to any module using either a dictionary variable
# or a dictionary itself.
- hosts: all
remote_user: root
# here we make a variable named "env" that is a dictionary
vars:
env:
HI: test2
http_proxy: http://proxy.example.com:8080
tasks:
# here we just define the dictionary directly and use it
# (here $HI is the shell variable as nothing in Ansible will replace it)
- shell: echo $HI
environment:
HI: test1
# here we are using the "env" map variable above
- shell: echo $HI
environment: "{{ env }}"
