Ansible is an open-source automation tool that simplifies the configuration management, application deployment, and task automation on multiple systems simultaneously. It is designed to be agentless, which means it doesn't require any software to be installed on the target machines. Instead, Ansible connects to the hosts using SSH and uses YAML-based scripts called playbooks to define the desired state of the system.
In some cases, when running Ansible tasks, you may need elevated privileges on the target machine. The sudo password is required when you want to execute commands as a privileged user (usually root) using become feature.
Here's how you can specify a sudo password in Ansible:
--ask-become-pass optionWhen running your Ansible playbook or command, include the --ask-become-pass option. For example:
ansible-playbook main.yml --ask-become-pass
Note: The
--ask-become-passoption tells Ansible to prompt you for the sudo password during execution.
---
- name: Hello, World! Playbook
hosts: localhost
gather_facts: false
tasks:
- name: Print Hello, World!
debug:
msg: "Hello, World!"
To avoid entering the password interactively, you can store the sudo password in a file. This is useful for automation and scripting purposes. However, ensure you secure the password file properly since it contains sensitive information.
Create a file (e.g., sudo_password.txt) and store the sudo password in it:
echo "your_sudo_password_here" > sudo_password.txt
Note: Replace
your_sudo_password_herewith the actual sudo password you want to use.
Set the permissions of the file to restrict access:
chmod 600 sudo_password.txt
Then, use the --ask-become-pass option with --become-password-file to reference the password file:
ansible-playbook main.yml --become-password-file=sudo_password.txt
Now, Ansible will use the password from the specified file during the execution.
---
- name: Hello, World! Playbook
hosts: localhost
gather_facts: false
tasks:
- name: Print Hello, World!
debug:
msg: "Hello, World!"
Keep in mind that storing passwords in plain text files may have security implications. Consider using password managers or other secure methods to handle sensitive data if possible. Also, in a more secure environment, consider using SSH keys for privilege escalation instead of passwords.
Ansible is an automation tool for configuration management, deployment, and task automation. To specify the sudo password, use --ask-become-pass interactively or --become-password-file with a password file. Secure sensitive data and consider SSH keys for better security.
