How to Resolve the Missing Sudo Password Error in Ansible Playbook

Ansible is an incredibly powerful tool for automating tasks and managing configurations across a multitude of servers. However, every so often, you might encounter the dreaded "Missing Sudo Password" error in your Ansible Playbook, which can bring your automation processes to a grinding halt. In this guide, we'll explore the causes of this error and provide solutions for intermediate and advanced users to resolve it effectively and securely.

This typically occurs when a task requires elevated privileges to execute, but the sudo password is not supplied or incorrectly configured. There are several ways to resolve this, each with its own merits and security considerations.

Step-by-Step Solutions

Using --ask-become-pass Option

One of the quickest ways to resolve the error is by using the --ask-become-pass option in your Ansible command. This option prompts you to enter the sudo password when the playbook runs.

This method is straightforward but might not be ideal for fully automated environments, as it requires manual intervention.

By setting become_ask_pass=True, Ansible will prompt you for the sudo password when needed. Yet again, this solution is more suitable for semi-automated workflows where some user interaction is permissible.

Storing Passwords Securely with ansible-vault

For more advanced use cases where full automation is necessary, storing passwords securely using ansible-vault is advised. Here's a brief overview of how to set this up:

Encrypt the Sudo Password:
