How can I write variables inside the tasks file in ansible
I have this play.yml
---
- hosts: 127.0.0.1
connection: local
sudo: false
tasks:
- include: apache.yml
My Apache look like this:
vars:
url: czxcxz
- name: Download apache
shell: wget {{url}}
This is giving me error.
If I remove vars
then it works. But I want to include the vars inside tasks so that I can keep different vars for different tasks separate.
Solution 1:
NOTE: Using set_fact
as described below sets a fact/variable onto the remote servers that the task is running against. This fact/variable will then persist across subsequent tasks for the entire duration of your playbook.
Also, these facts are immutable (for the duration of the playbook), and cannot be changed once set.
ORIGINAL ANSWER
Use set_fact
before your task to set facts which seem interchangeable with variables:
- name: Set Apache URL
set_fact:
apache_url: 'http://example.com/apache'
- name: Download Apache
shell: wget {{ apache_url }}
See http://docs.ansible.com/set_fact_module.html for the official word.
Solution 2:
I know, it is long ago, but since the easiest answer was not yet posted I will do so for other user that might step by.
Just move the var inside the "name" block:
- name: Download apache
vars:
url: czxcxz
shell: wget {{url}}
Solution 3:
Variable definitions are meant to be used in tasks. But if you want to include them in tasks probably use the register
directive. Like this:
- name: Define variable in task.
shell: echo "http://www.my.url.com"
register: url
- name: Download apache
shell: wget {{ item }}
with_items: url.stdout
You can also look at roles as a way of separating tasks depending on the different roles roles. This way you can have separate variables for each of one of your roles. For example you may have a url
variable for apache1
and a separate url
variable for the role apache2
.
Solution 4:
In Your example, apache.yml is tasklist, but not playbook
In depends on desired architecture, You can do one of:
Convert apache.yml to role. Then define tasks in roles/apache/tasks/mail.yml and variables in roles/apache/defaults/mail.yml (vars in defaults can be overriden when role applied)
Set vars in play.yml playbook
play.yml
