How to Add Execute Permission 755 on Linux file with Ansible?

I’m going to show you a live demo and some simple Ansible code. I’m Luca Berton and welcome to today’s episode of Ansible Pilot.

Ansible Add Execute Permission

ansible.builtin.file
Manage files and file properties

Today we’re talking about the Ansible module file. The full name is ansible.builtin.file, which means that is part of the collection of modules “builtin” with ansible and shipped with it. It’s a module pretty stable and out for years. It works in a different variety of operating systems. It manages files and file properties. For Windows targets, use the ansible.windows.win_file module instead.

Main Parameters

path string (dest, name) - file path
owner string - user
group string - group
mode raw - Ex: ‘0644’ or ‘u=rw,g=r,o=r’
state string - file/absent/directory/hard/link/touch
setype/seuser/selevel - SELinux

This module has some parameters to perform any tasks. The only required is “path”, where you specify the filesystem path of the file you’re going to edit. The parameter “owner” set the user that should own the file/directory. The parameter “group” set the group that should own the file/directory. The parameter “mode” set the permissions in the UNIX way of the file/directory. The state defines the type of object we are modifying, the default is “file” but we could handle also directories, hard links, symlinks, or only update the access time with the “touch” option. Let me also highlight that we could also specify the SELinux properties.

How to Add Execute Permission 755 file on Linux with Ansible Playbook. I’m going to show you how to set the chmod +x of an example.sh Linux file with Ansible.

code

file_permission.yml

- name: file module demo
  hosts: all
  vars:
    myscript: "~/example.sh"
  tasks:

      ansible.builtin.file:
        dest: "{{ myscript }}"
        mode: 'a+x'

example.sh

#!/bin/bash
echo "Hello World"
