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 }}"

azure_networkinterfaces seems to be a return value of azure_rm_networkinterface_facts so it's normal that it doesn't exist...
I'd write a playbook like this:
- name: "Get facts for network interface by it's name"
azure_rm_networkinterface_facts:
resource_group: "{{ target_resourcegroup }}"
name: "{{ target_nic_name }}"
register: output
I suggest you debug the output variable to check your return values. I don't know the version of Azure you are using and a lot of changes can exist depending on it.
- name: "Display return value"
debug:
msg: "{{ output }}"
You could play with output.azure_networkinterfaces or output.networkinterfaces
Following the last documentation, its seems azure_rm_networkinterface_fact is deprecated, replaced by azure_rm_networkinterface_info
azure_rm_networkinterface_info
I'm new to Ansible and trying to get a service state where the service name is dynamic and set by set_fact before in the playbook.
How can you build a variable within another variable?
I wish I could use something like that to display my service state :
{{ ansible_facts.services['{{ servicename }}'].state }}
But well it doesn't work.
So I tried this way with vars :
- name: set service name
ansible.builtin.set_fact:
servicename: "'myservice'"
when: ansible_distribution_major_version == "7"
- name: print service state
debug: msg={{ vars['ansible_facts.services[' + servicename + '].state'] }}
vars:
servicename: "{{ servicename }}"
I got the following error :
fatal: [myhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute u\"ansible_facts.services['myservice'].state\"\n\nThe error appears to be in '/etc/ansible/playbook/myplaybook.yaml': line 20, 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: print service state\n ^ here\n"}
When the following works just fine :
- name: print service state
debug:
msg: "{{ ansible_facts.services['myservice'].state }}"
Inside a {{ … }} block, you can access the variables directly. And from my point of view, you can leave the ansible_facts out, as well as the variable assignment in the second task.
This will do what you want (and as Zeitounator already wrote):
- hosts: localhost
vars:
services:
myservice:
state: foo
tasks:
- name: set service name
ansible.builtin.set_fact:
servicename: "myservice"
- name: print service state
debug:
msg: "{{ services[servicename].state }}"
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 am having an issue with the Ansible script module interpreting a with_items variable.

When I run the playbook I get the following error:

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
How can I access a variable of other host? I'd like to access the slack_token varaiable of my localhost on the working_host.
- hosts: localhost
vars:
slack_token: 123123123
tasks:
- block:
- name: test
debug: msg="{{ slack_token }}"
- hosts: "{{ working_host }}"
vars:
slack_token: "{{ hostvars['localhost']['slack_token'] }}"
tasks:
- block:
- name: test2
debug: msg={{ slack_token }}
The error message:
fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field
'args' has an invalid value, which appears to include a variable that
is undefined. The error was: {{ hostvars['localhost']['slack_token']
}}: 'dict object' has no attribute 'slack_token'
Any idea?
Just answered a somewhat same question in my previous post.
Here's what I used:
set_fact:
myVar: "{{ hostvars[groups['all'][0]]['slack_token'] | default(False) }}"
But you're using two plays in a playbook.
You can also try to copy a file to a machine stating the fact.
To access slack_token from everywhere, either:
pass it as extra variable with -e slack_token=zzzz
define it in your inventory under all group
