In Ansible, the become directive executes tasks or playbooks with privilege escalation, allowing you to perform actions as a different user, typically with administrative or root privileges. Here’s an example of how you can use become in Ansible:
---
- name: Example Playbook
hosts: all
become: yes
become_method: sudo
become_user: root
tasks:
- name: Update packages
package:
name: '*'
state: latest
The playbook specifies that all tasks should be executed with elevated privileges using the become: yes directive in the above example. The become_method parameter is set to sudo, indicating that the sudo command will be used for privilege escalation. The become_user parameter is set to root, indicating that the tasks should be executed as the root user.
The tasks section contains a simple task to update all packages on the target hosts. The package module is used with the name parameter set to ‘*’, which will update all installed packages. The state parameter is set to latest, ensuring all packages are updated to their latest versions.
You can save this playbook to a file, for example, example-playbook.yml, and run it using the ansible-playbook command:
ansible-playbook example-playbook.yml
Make sure to replace all in the hosts directive with the appropriate host or group of hosts you want to target.
Note: The become directive requires appropriate permissions on the target hosts, such as password-less sudo access for the specified user.
