Run Ansible Task in localhost - ansible

Question

I need to check one file (/tmp/test.html) exist on localhost and if it exist execute the other tasks.
Can you please help to run this first task (name: Check exist and copy) in localhost(workstation).
localhost: workstation
remotehost: servera,serverb
Below is my playbook.yml
---
- name: Check exist and copy
hosts: all
tasks:
- name: check if file is exists #need to execute this task in workstation
stat:
path: /tmp/test.html
register: file_present
- name: copy to taggroup 1
copy:
src: /tmp/test.html
dest: /tmp/dest1.html
when: file_present.stat.exists == 0 and inventory_hostname in groups ['taggroup1']
- name: copy to taggroup 2
copy:
src: /tmp/test.html
dest: /tmp/dest2.html
when: file_present.stat.exists == 0 and inventory_hostname in groups ['taggroup2']

Answer 1

Module stat is not needed when paths are tested at localhost. For example fail the play if the file /tmp/test.html does not exist and continue the play otherwise.
- hosts: all
vars:
my_file: '/tmp/test.html'
tasks:
- fail:
msg: "{{ my_file }} does not exist. End of play."
when: my_file is not exists
delegate_to: localhost
run_once: true
- debug:
msg: "Continue play."
run_once: true

Try the following:
---
- name: Check exist and copy
hosts: all
tasks:
- name: check if file is exists #need to execute this task in workstation
stat:
path: /tmp/test.html
register: file_present
delegate_to: localhost
- name: copy to taggroup 1
copy:
src: /tmp/test.html
dest: /tmp/dest1.html
when: file_present.stat.exists and inventory_hostname in groups ['taggroup1']
- name: copy to taggroup 2
copy:
src: /tmp/test.html
dest: /tmp/dest2.html
when: file_present.stat.exists and inventory_hostname in groups ['taggroup2']
See the docs.
You can use delegate_to: to run a task on a different machine than the current ansible_host.
