Loop multiple times to create multiple directory - ansible

Question

I would like to loop many times to create multiple directory. I tried below was not working.
Would you be able to advice?
This my variable
main_dir:
- "/exec/db/dir1"
- "/exec/db/dir1/v1"
sub_dir:
- { directory: "subdir/database/connection", directory: "db_connection.xml" }
- { directory: "subdir/database/properties", directory: "application.properties" }
- { directory: "subdir/application", directory: "index.html" }
- { directory: "subdir/application/pom", directory: "pom.xml" }
This my playbook role
- name: Create multiple sub directory
file:
path: "{{ item[0] }}/{{ item[1].directory }}"
state: directory
with_nested:
- "{{ main_dir }}"
- "{{ sub_dir }}"
Expected result
/exec/db/dir1/subdir/database/connection
/exec/db/dir1/subdir/database/properties
/exec/db/dir1/subdir/application
/exec/db/dir1/subdir/application/pom
/exec/db/dir1/v1/subdir/database/connection
/exec/db/dir1/v1/subdir/database/properties
/exec/db/dir1/v1/subdir/application
/exec/db/dir1/v1/subdir/application/pom

It looks like the dictionaries in your list sub-dir are bogus.
Indeed, you have as directory key for both what seems to be a directory and what seems to be a file.
Your variable would be more correct this way:
sub_dir:
- { directory: "subdir/database/connection", file: "db_connection.xml" }
- { directory: "subdir/database/properties", file: "application.properties" }
- { directory: "subdir/application", file: "index.html" }
- { directory: "subdir/application/pom", file: "pom.xml" }
And with that dictionary, your playbooks works properly because the file does not override the directory anymore.
Given the playbook:
- hosts: all
gather_facts: no
tasks:
- file:
path: "{{ item[0] }}/{{ item[1].directory }}"
state: directory
with_nested:
- "{{ main_dir }}"
- "{{ sub_dir }}"
vars:
main_dir:
- "/exec/db/dir1"
- "/exec/db/dir1/v1"
sub_dir:
- { directory: "subdir/database/connection", file: "db_connection.xml" }
- { directory: "subdir/database/properties", file: "application.properties" }
- { directory: "subdir/application", file: "index.html" }
- { directory: "subdir/application/pom", file: "pom.xml" }
This give the recap:
PLAY [all] ************************************************************************************************************************
TASK [file] ***********************************************************************************************************************
changed: [localhost] => (item=['/exec/db/dir1', {'directory': 'subdir/database/connection', 'file': 'db_connection.xml'}])
changed: [localhost] => (item=['/exec/db/dir1', {'directory': 'subdir/database/properties', 'file': 'application.properties'}])
changed: [localhost] => (item=['/exec/db/dir1', {'directory': 'subdir/application', 'file': 'index.html'}])
changed: [localhost] => (item=['/exec/db/dir1', {'directory': 'subdir/application/pom', 'file': 'pom.xml'}])
changed: [localhost] => (item=['/exec/db/dir1/v1', {'directory': 'subdir/database/connection', 'file': 'db_connection.xml'}])
changed: [localhost] => (item=['/exec/db/dir1/v1', {'directory': 'subdir/database/properties', 'file': 'application.properties'}])
changed: [localhost] => (item=['/exec/db/dir1/v1', {'directory': 'subdir/application', 'file': 'index.html'}])
changed: [localhost] => (item=['/exec/db/dir1/v1', {'directory': 'subdir/application/pom', 'file': 'pom.xml'}])
PLAY RECAP ************************************************************************************************************************
localhost : ok=1 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
Which creates the directory tree:
