Hi Evrybody,
I'm facing to a problem that I don't understand the origin: Any help will
be welcome.
I want to use in a playbook a role where the name depends on a variable
defined in the inventory.
I have the following dynamic inventory for a host:
the command ansible-inventory -i /etc/ansible/cobbler.py --host
"rhel8-test-2" returns:
{
"cobbler": {
...
"image": "",
"ks_meta": {},
"mgmt_classes": [
"online",
],
"name": "rhel8-test-2",
"netboot_enabled": true,
"power_user": "",
"profile": "HWCL_402"
}
}
In my playbook I want to acess to the profile variable =>
"cobbler.profile": "HWCL_402"
The following playbook works fine:
---
- name: " print profile"
hosts: "{{ myhost }}"
gather_facts: no
vars:
PROFILE: "{{ hostvars[inventory_hostname].cobbler.profile }}"
tasks:
- name: print profile value defined in inventory
ansible.builtin.debug:
msg: "{{ PROFILE }}"
This playbook prints the correct value of my variable:
ansible-playbook -i /etc/ansible/cobbler.py playbook2.yml -e
"myhost=rhel8-test-2"
PLAY [print profile]
*******************************************************************************************
TASK [print profile value defined in inventory]
*******************************************************************************************
ok: [rhel8-test-2] => {
"msg": "HWCL_402"
}
...
Now, , I add the call to a role ( echo ) where the path depends on
profile value:
-> the role is under HWCL_402/echo
---
- name: " use profile"
hosts: "{{ myhost }}"
gather_facts: no
vars:
PROFILE: "{{ hostvars[inventory_hostname].cobbler.profile }}"
tasks:
- name: print profile value defined in inventory
ansible.builtin.debug:
msg: "{{ PROFILE }}"
*roles:*
* - "{{ PROFILE }}/echo"*
the execution of this modifified playbook returns immediatly :
*ERROR! {{ hostvars[inventory_hostname].cobbler.profile }}:** 'hostvars' is
undefined*
what I did wrong ? why hostvars is undefined ? it was correct in the
previous example ?
If I declare PROFILE in a simple variable ( not in the inventory) it
'works also fine !
Best regards.
Philippe.
