How to Use Ansible-Lint and Example Output

Using Ansible-lint is straightforward. Once installed, you can run it against your Ansible playbook to identify potential issues. Here’s how you do it: 🚀

1. Navigate to your project’s directory where your playbook is located.
2. Run the command ansible-lint your_playbook.yml.

Here’s an example command and its output: 📄

$ ansible-lint site.yml

Example output: 📄

[206] Variables should have spaces before and after: {{ var_name }}
roles/my_role/tasks/main.yml:5
    command: echo {{my_var}}

[208] File permissions unset or incorrect
roles/my_role/tasks/main.yml:10
    copy: src=/my/file dest=/my/dest mode=644

This output indicates that there are two potential issues: 🚨

• The first is a formatting issue with variable usage in roles/my_role/tasks/main.yml.
• The second is a best practice warning about file permissions in a copy task.

By addressing these issues, you can improve the quality and reliability of your Ansible playbooks. ✨
