Ansible troubleshooting - Error 205: playbook-extension

Ansible Error 205, “playbook-extension,” ensures playbooks use `.yml` or `.yaml` extensions for proper YAML format.

Introduction

Ansible, a popular automation tool, simplifies the management of configurations, deployment of software, and execution of tasks through its YAML-based playbooks. These playbooks, expressed in YAML format, are at the heart of Ansible’s automation capabilities. In this article, we’ll explore Ansible Error 205, “playbook-extension”, in [Ansible-Lint](/articles/ansible-lint) which focuses on the importance of using the correct file extension for Ansible playbooks. We’ll discuss why choosing .yml or .yaml extensions is crucial and how it ensures the smooth functioning of your Ansible automation tasks.

The Problem: Incorrect File Extensions

Ansible Error 205, “playbook-extension,” is designed to check if Ansible playbooks have the correct file extension. Playbooks should use either the .yml or .yaml file extension, as these extensions are associated with YAML-formatted files, which is the standard format for Ansible playbooks.

Problematic Code Example:

``yaml


---
name: Example playbook without the proper extension
  hosts: all
  tasks:
    - name: Ensure some task is completed
      ansible.builtin.debug:
        msg: "This is a sample playbook"

In the code above, the playbook lacks the .yml or .yaml file extension, which can lead to confusion and issues when managing and executing Ansible playbooks.



Correcting the File Extension
To address Ansible Error 205 and ensure the compatibility and proper recognition of your playbooks, it’s crucial to save your Ansible playbooks with the correct file extension. Here’s how you can do it:

`yaml


---
name: Correctly named Ansible playbook
  hosts: all
  tasks:
    - name: Ensure a task is completed
      ansible.builtin.debug:
        msg: "This is a sample playbook"

In the corrected code, the playbook has been saved with the .yml extension, which is the recommended practice for Ansible playbooks.



Benefits of Using the Correct Extension

1. Recognition and Interpretation: The correct file extension (.yml or .yaml) ensures that your playbook is recognized as YAML-formatted, making it interpretable by Ansible.


2. Standardization: Using the recommended file extension standardizes your playbook naming conventions and fosters consistency across your automation tasks.
3. Clarity and Best Practices: It aligns with Ansible best practices and makes your playbook’s purpose and structure clear to you and other team members.
4. Avoiding Errors: Using the wrong file extension can lead to errors and issues when managing and executing playbooks, which can be avoided by following the standard.
