Ansible troubleshooting - Error: name[prefix]
How to Solve the Ansible Error name[prefix]
In the world of Ansible, effective organization and naming conventions are paramount. It’s these names that help you identify and document tasks and plays, which is vital for clarity, troubleshooting, and understanding the operations being executed. Ansible has several rules to ensure proper naming, one of which is
The Significance of Task Naming
Whether it’s for error checking or a cleaner playbook structure, task naming plays a crucial role in your Ansible code. The
name[prefix] rule is designed to help you establish a clear naming structure for tasks, particularly those found in sub-task files.
This rule is specific to task files that are not named
main.yml. It suggests the inclusion of a prefix in the task name. For example, if you have a task named “Restart server” inside a file named
tasks/deploy.yml, the rule recommends renaming it to
deploy | Restart server.
Why is This Rule Important?
In complex roles or playbooks with multiple task files, it can often become challenging to understand which task belongs to which file. Adding a prefix, in combination with Ansible’s automatic role name assignment, significantly eases the process of tracking and troubleshooting roles within your playbooks.
How to Implement
It’s important to note that this rule is opt-in, meaning you need to add it to your Ansible Lint
enable_list to activate it. Once enabled, it will guide you in prefixing task names in sub-task files for more straightforward playbook organization.
Let’s examine a brief example to understand its significance:
--- - hosts: all tasks: - name: Create placefolder file ansible.builtin.command: touch /tmp/.placeholder
Ansible Lint Output

Last profile that met the validation criteria was 'min'.

By implementing the
name[prefix] rule, you enhance your Ansible playbook’s clarity and maintainability.
name[prefix] rule is part of Ansible’s effort to improve code standards and enhance the overall Ansible experience. It’s a valuable addition to your Ansible toolkit, especially when dealing with complex, multi-file playbooks.
name[prefix] rule serves as an optional but highly valuable addition to your Ansible playbook development toolkit. By encouraging the use of prefixes in task names for sub-task files, it significantly improves playbook readability and maintainability, especially in complex roles and playbooks with multiple sub-task files.
The rule’s design, contributed by the Red Hat Community of Practice, aims to address the challenge of identifying which task belongs to which file in intricate Ansible structures. Adding prefixes to task names, combined with Ansible’s automatic role name inclusion, makes it considerably easier to track and troubleshoot role plays, reducing potential confusion and increasing overall efficiency.
name[prefix] sub-rule remains optional, considering its adoption can be a wise choice, especially when dealing with extensive Ansible projects. By using this practice in your development, you not only enhance the clarity and organization of your playbooks but also pave the way for smoother troubleshooting and easier collaboration within your Ansible team.
