Manage environment variables with ansible - environment-variables

Question

i need set the environment variable to build some app at startup, i use vars in the playbook file:
---
- hosts: all
sudo: yes
vars:
build_env:
VAR1: value1
VAR2: value2
VAR3: value3
And set with environment into task to build app
- name: Build app
environment: "{{build_env}}"
command: "{{ item }} chdir={{app1}}"
with_items:
- npm install
- bower
- gulp
Also i need add the same variables to /etc/environment but i would not replicate the same variables in another task, any idea?

ansible-playbook -c local -i 127.0.0.1, test.yml
test.yml:
---
- hosts: all
sudo: yes
vars:
build_env:
VAR1: value1
VAR2: value2
VAR3: value3
tasks:
- name: Build app
environment: "{{build_env}}"
shell: source /etc/environment; echo $VAR1 > ~/111
- name: Build app
environment: "{{build_env}}"
shell: source /etc/environment;env >> /root/111
Tested vars:
# cat /etc/environment
VAR1=2
export VALERY=x
export VAR2=ss
CCCCCCCCCC=xx
The result:
# cat ~/111
value1
HOSTNAME=38b07f75ca28
SHLVL=1
HOME=/root
VALERY=x
_=/usr/local/bin/ansible-playbook
TERM=xterm
VAR1=value1
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
VAR2=value2
VAR3=value3
LANG=C
LC_MESSAGES=C
PWD=/
LC_ALL=C
Conclusiosn:
CCCCCCCCCC=xx - wasn't exported
The environment: override the variables, so you should export all
variables in /etc/environment
