I am trying to use a vars file within a playbook - in this case to set a machine's hostname.
$ cat data_machine_test.yml
---
host_name: test02
$ cat os-build_hostname_set.yml
---
- name: Set hostname
hosts: all
gather_facts: no
vars_files:
- data_machine_test.yml
tasks:
- name: Set hostname
hostname:
name: "{{ host_name }}"
The variable file appears to be being read ...
PLAY [Set hostname] ************************************************************
META: ran handlers
Read vars_file 'data_machine_test.yml'
... but I keep getting the error ...
"msg": "The task includes an option with an undefined variable. The error was: 'host_name' is undefined\n\nThe error appears to have been in '/var/lib/awx/projects/_6__unix/os-build_hostname_set.yml': line 10, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Set hostname\n ^ here\n",
"_ansible_no_log": false
Code:

host_name: test02
$ cat os-build_hostname_set.yml

- name: Set hostname
hosts: all
gather_facts: no
vars_files:
- data_machine_test.yml
tasks:
- name: Set hostname
hostname:

Output:
It appears that the variables file is being read ...

In the below playbook, can someone please tell me what is wrong with the syntax of the final set_fact statement. If i explicitly specify the hostname R9 (as per the first set_fact), then it works without issue. But if I assign a variable to have a value of R9, and then use this in the final set_fact statement, I get the error shown below. Argh.

you can use the inventory_hostname for your purpose:
- set_fact:
another_var: "{{ hostvars[inventory_hostname].results }}"
I have a questions since I am giving crazy. I want to compare stdout result to one variable storaged in my vars file.
For instance, instead of using the variable but the string ( The IP 22.22.2.2), it works:
Nets.yml
- List_nets_find:
- host 22.22.2.2
Playbook:
---
- name: Black List
hosts: routers
gather_facts: false
vars_files:
- vars/Nets.yml
tasks:
- name: Check the object-group
ios_command:
commands:
- command: "show object-group BLOCK-LIST"
register: output
tags:
- see
- debug:
msg: included
when: output.stdout is search('22.22.2.2')
tags:
- see
Result:
TASK [debug] **************************************************************************************************************************************************************************************
skipping: [Router1]
ok: [Router3] => {
"msg": "included"
}
ok: [Router2] => {
"msg": "included"
}
But instead of using the string, I use the Variable, it does not work.
- name: Black List
hosts: routers
gather_facts: false
vars_files:
- vars/Nets.yml
tasks:
- name: Check the object-group
ios_command:

- command: "show object-group BLOCK-LIST"
register: output
tags:

- debug:
msg: included
when: output.stdout is search('{{List_net_find}}')
tags:

This is the error:
fatal: [Router1]: FAILED! => {"msg": "The conditional check 'output.stdout is search('{{List_net_find}}')' failed. The error was: error while evaluating conditional (output.stdout is search('{{List_net_find}}')): 'List_net_find' is undefined\n\nThe error appears to be in '/home/ansible/Ios_ACL_LAB/object-group.yml': line 23, column 10, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n - see\n - debug:\n ^ here\n"}

Any suggestion? or other way to do it?
Thanks so much!
Your vars/Nets.yml does not declare a variable named List_nets_find, it declares an anonymous list whose first element is a dict whose only key is named List_nets_find
If you want a variable named that, then change - List_nets_find: to be List_nets_find:
Separately, the next question you are going to ask is "why does my search not match anything" and that's because List_nets_find is a list of str, so you will want to change that test to be output.stdout is search(List_nets_find | map("regex_escape") | join("|")), using the regex_escape filter to turn those strings into something that can be safely fed into a search alternation
Executing parent.yml which in turn calls child.yml playbook for execution with dynamic variables.
Variables from parent.yml aren`t interpolated inside child.yml playbook. Correct me if I am using correct syntax?

include_task expects a list of tasks but you give it a complete playbook.
Child.yml should only contain what is currently below the line "tasks:".

I would like to use inventory_hostname as part of a dictionary lookup to configure servers that use the same template, but with different variables
/etc/ansible/hosts
[nodes]
node1 ansible_host=192.168.0.2
roles/role/defaults/main.yml
node1:
if1: eth1
ip1: 1.1.1.1/11
node2:
if1: eth4
ip1: 4.4.4.4/44
roles/role/tasks/main.yml
- name: test
debug:
msg: "{{ [inventory_hostname].[if1] }} end test "
expected this to display eth1 on the console but got the error
fatal: [node1]: FAILED! => {
"msg": "The task includes an option with an undefined variable. The error was: 'if1' is undefined\n\nThe error appears to have been in '/root/ansible/roles/role/tasks/main.yml': line 6, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: test\n ^ here\n"
}
What you are looking for is vars:
- name: test
debug:
msg: "{{ vars[ansible_hostname]['if1'] }} end test"
I am having an issue with the Ansible script module interpreting a with_items variable.

When I run the playbook I get the following error:
TASK [vsa_deploy_config : Deploy VSAs on Center] *******************************************************************************
fatal: [auto-win1.lab.com]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined.

to retry, use: --limit #/opt/ansible/powershell.retry
The first task using the template module interprets the item.vsa_hostname variable correctly, but the script module does not. Is the script module not capable of using with_items?
There is no with_items for your script task:
- name: Deploy VSAs on Center # -\
script: "files/{{ item.vsa_hostname }}.ps1" # \
register: out # / This is task1
when: target == "win_center" # -/
- debug: var=out # -\
with_items: # > This is task2
- "{{ vsa_center }}" # -/
I guess you'd want to move debug to the very bottom:
- name: Deploy VSAs on Center
script: "files/{{ item.vsa_hostname }}.ps1"
register: out
when: target == "win_center"
with_items: "{{ vsa_center }}"
- debug: var=out
P.S. also there is no need to feed unnecessary nested list into with_items.
just move the line - debug: var=out to the end of the file and it will work
