[ansible-project] inventory_dir is still present as a global variable in Ansible 2.4 ?

2018-03-07 Thread ishan jain 
Hi All,

I am trying to understand the changes with Ansible 2.4 that affects the 
usage of inventory_dir variable.

Earlier i was using a static host file and in my playbooks, i was heavily 
relying on inventory_dir to load variable files which in turn was loading 
the target hosts. I understand the purpose of making the inventory_dir as a 
hostvar, what i did not understand is *how can i still access inventory_dir 
directly as a global variable in my playbooks* *?*

To show what i mean, i created a little demo:

*hosts.info*
[locals]
local1 localhost ansible_connection=local
local2 localhost ansible_connection=local



*varsFile.yaml*
#This doesn't work anymore
#moreVars: "{{ inventory_dir ~ 'moreVars.yaml' }}"

#This also works
#moreVars: "{{hostvars[groups.all.0].inventory_dir}}/moreVars.yaml"

#This works and this is what i was using before 2.4
moreVars: "{{inventory_dir}}/moreVars.yaml"



*moreVars.yaml*
#Prior to 2.4, this is how i defined target hosts. I understand this will 
not work anymore
targetHosts: locals

who: MORE_VARS



*playbook.yaml*
---
- hosts: locals
  vars_files:
- varsFile.yaml
- "{{moreVars}}"

  tasks:


 - debug: var=who

 - name: Accessing the inventory_dir as a host var
   debug: msg="Accessing inventory_dir as hostvar -- 
{{hostvars[groups.all.0].inventory_dir}}"

 - name: Accessing the inventory DIR directly
   debug: msg="Accessing inventory_dir directly -- {{inventory_dir}}"




*output*






*$ ansible --versionansible 2.4.3.0$ ansible-playbook playbook.yaml -i 
hosts.infoPLAY [locals] 
***TASK
 
[Gathering Facts] 
**ok:
 
[local1]ok: [local2]TASK [debug] 
ok:
 
[local1] => {"who": "MORE_VARS"}ok: [local2] => {"who": 
"MORE_VARS"}TASK [Accessing the inventory_dir as a host var] 
ok:
 
[local1] => {"msg": "Accessing inventory_dir as hostvar -- 
/home/ij/temp"}ok: [local2] => {"msg": "Accessing inventory_dir as 
hostvar -- /home/ij/temp"}TASK [Accessing the inventory DIR directly] 
*ok:
 
[local1] => {"msg": "Accessing inventory_dir directly -- 
/home/ij/temp"}ok: [local2] => {"msg": "Accessing inventory_dir 
directly -- /home/ij/temp"}PLAY RECAP 
**local1
  
   : ok=4changed=0unreachable=0failed=0local2  
   : ok=4changed=0unreachable=0failed=0*


*So my questions:*
*1) How is inventory_dir still available as global var ?*
*2) Can i continue using it directly or i should 
use hostvars[groups.all.0].inventory_dir ?*
