In this page, We are going to see how to download shell scripts from remote machine and run downloaded shell scripts on local machine in ansible playbook.

synchronize ansible module will be used to download the shell scripts from remote machine to local machine (controller machine) using pull mode.

Using command ansible module, running shell scripts on local machines and reading generated output file content and displaying via ansible tasks.

---
- name: Create directory on local machine
  hosts: localhost
  tasks:
    - name: "creating directory"
      file:
    	state: directory
    	path: /home/user2/ansible/test_shell
    	mode: 0750

- name: Download shell scripts from remote machine
  hosts: 128.23.4.51
  tasks:
    - name: download shell scripts
      synchronize:
    	mode: pull
    	src: /home/user1/test_shell/get_host_name.sh
    	dest: /home/user2/ansible/test_shell/get_host_name.sh

- name: Run shell scripts on local machine
  hosts: localhost
  tasks:
    - name: run get_host_name.sh
      shell: ". /home/user2/ansible/test_shell/get_host_name.sh"

    - name: read file content
      command: "cat /home/user2/ansible/shell_file"
      register: out

    - name: Print the msg
      debug:
    	msg: "{{ out.stdout }}"

Above ansible playbook, creates directory and download shell scripts under created directory '/home/user2/ansible/test_shell' on local machine.

Once shell scripts are executed on local machine, output file is generated under '/home/user2/ansible/test_file' on local machine.

Lets see the shell scripts to get host name in output file,

#!/bin/bash

echo $(hostname -f) > shell_file

Lets run the ansible playbook 'download-shell-scripts-from-remote.yml' contains above code,

Output:

$ ansible-playbook download-shell-scripts-from-remote.yml
