I have the following regex in my playbook:

  • name: get business ID
    set_fact:
    my_var: “{{ inventory_hostname | regex_findall(‘.+?(?=-).+?(?=-).+?(?=-).+?(?=-)+’) }}”

the debug returns the right value:

ok: [DE-LEI-GRO-GROLE-F001-FW01-MDF] => {
“my_var”: [
“DE-LEI-GRO-GROLE”

when using create directory

  • name: create directory
    file:
    path: /home/vinn/devicebackups/{{ my_var }}
    state: directory

its creates the directory adding [’ ’]

“path”: “/home/vinn/devicebackups/[''DE-LEI-GRO-GROLE’]”,

any idea why??

thanks a lot

I have the following regex in my playbook:
   - name: get business ID
     set_fact:
       my_var: "{{ inventory_hostname |
regex_findall('.+?(?=-).+?(?=-).+?(?=-).+?(?=-)+') }}"

the debug returns the right value:

ok: [DE-LEI-GRO-GROLE-F001-FW01-MDF] => {
    "my_var": [
        "DE-LEI-GRO-GROLE"

  The bracket '[' tells us the variable my_var is a list. It's not
  clear how the set_fact above managed to create the list.

when using create directory
   - name: create directory
     file:
       path: /home/vinn/devicebackups/{{ my_var }}
       state: directory

its creates the directory adding [' ’]

"path": "/home/vinn/devicebackups/[''DE-LEI-GRO-GROLE’]",

any idea why??

  The variable my_var is a list.

The filter regex_findall returns a list of matches

could it be that hyphen - are not allowed in the variable string?
