Hello,
I have some trouble on reusing a code wrote for Ansible 2.1.1.0 with
Ansible 2.3.1.0.
With Ansible 2.3 when I try reading, from a task of a role, a nested
variable that comes from "group_vars", tells me that variable isn't define.
I remove all unnecessary from my code and create an example code
(following).
The structure is :
- test.yml
- group_vars:
- db.yml
- hosts:
- dev
- roles:
- dbtest:
- tasks:
- main.yml
Where "test.yml" is:
- name: test
hosts: db
gather_facts: false
roles:
- dbtest
"db.yml" under group_vars is:
databases:
- name: dbName
encoding: utf8
"dev" under "hosts" is :
[local-db]
localhost
[db:children]
local-db
"main.yml" under "roles/dbtest/tasks" is:
- name: 'Print databases'
debug:
var: databases
- name: 'Item'
debug:
var: item
with_items: databases
- name: 'Item Name'
debug:
var: item.name
with_items: databases
When I run the code with Ansible 2.1.1.0 calling
ansible-playbook -i hosts/dev test.yml
,I got this output:
PLAY [test]
********************************************************************
TASK [dbtest : Print databases]
************************************************
ok: [localhost] => {
"databases": [
{
"encoding": "utf8",
"name": "dbName"
}
]
}
TASK [dbtest : Item]
***********************************************************
ok: [localhost] => (item={u'name': u'dbName', u'encoding': u'utf8'}) => {
"item": {
"encoding": "utf8",
"name": "dbName"
}
}
TASK [dbtest : Item Name]
******************************************************
ok: [localhost] => (item={u'name': u'dbName', u'encoding': u'utf8'}) => {
"item": {
"encoding": "utf8",
"name": "dbName"
},
"item.name": "dbName"
}
PLAY RECAP
*********************************************************************
localhost : ok=3 changed=0 unreachable=0 failed=0
When I run with Ansible 2.3.1.0 the output is:
PLAY [test]
**********************************************************************************************************
TASK [dbtest : Print databases]
**************************************************************************************
ok: [localhost] => {
"databases": [
{
"encoding": "utf8",
"name": "dbName"
}
]
}
TASK [dbtest : Item]
*************************************************************************************************
ok: [localhost] => (item=databases) => {
"item": "databases"
}
TASK [dbtest : Item Name]
********************************************************************************************
ok: [localhost] => (item=databases) => {
"item": "databases",
"item.name": "VARIABLE IS NOT DEFINED!"
}
PLAY RECAP
***********************************************************************************************************
localhost : ok=3 changed=0 unreachable=0 failed=0
As you can see, on the last step when I try to read "item.name" the old one
works, the new one doesn't see the variable.
I'd like to understand if is possible and how modify my code in order that
will work also with Ansible 2.3 (considering that in my full code I widely
use nested variable as describe above.
Tell me if you need more information and if you have any suggestion, thanks
Paolo
