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

*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 ?*
