How to Solve the Ansible Error 703 meta-incorrect
In the world of automation and infrastructure management, Ansible has emerged as a powerful tool for simplifying complex tasks. It provides an efficient way to manage and configure systems. When working with Ansible, organization and documentation are key, and that’s where metadata plays a vital role. Ansible Rule 703, “
meta-incorrect,” ensures that your role metadata adheres to certain standards.
Understanding Role Metadata
Roles are a fundamental concept in Ansible. They encapsulate a set of tasks, variables, and templates, making it easier to organize and reuse automation logic. Each role can have associated metadata, defined in the
meta/main.yml file. Metadata helps describe the role and provides important information about it.
The Significance of Rule 703
Rule 703, “
meta-incorrect,” checks role metadata for fields with undefined or default values. It enforces the convention of setting appropriate values for specific metadata fields in the
The metadata fields that should have defined values are:
Rule 703 ensures that these fields are not left with placeholder or default values. Let’s explore why adhering to this rule is essential.
Problematic Code vs. Correct Code
Let’s compare problematic code that violates Rule 703 with the correct code that aligns with the rule’s recommendations.
Metadata fields for the role contain default values.

This rule is not skippable and stops further processing of the file. If incorrect schema was picked, you might want to either: * move the file to standard location, so its file is detected correctly. * use ``kinds:`` option in linter config to help it pick correct file type.

As you can see, the correct code provides specific and meaningful values for each metadata field. This practice ensures that the metadata accurately describes the role and provides users with essential information.
Why Conform to Rule 703?
Adhering to Rule 703, “
meta-incorrect,” offers several advantages for role management:
1. Clarity: Well-defined metadata fields make it clear who authored the role, what it does, and under which license it’s distributed.
2. Documentation: Properly filled metadata acts as a form of documentation for anyone using the role, making it easier to understand its purpose and origin.
3. Professionalism: When you provide accurate and meaningful information in your role’s metadata, it demonstrates professionalism and responsibility in your automation projects.
In conclusion, Ansible Rule 703, “
meta-incorrect,” encourages you to set appropriate values for your role’s metadata fields. This practice improves the clarity and documentation of your roles and reflects professionalism in your automation work. When sharing roles with the Ansible community or your team, well-structured metadata can make a significant difference in how your automation is received and utilized. It’s a small but impactful step in ensuring the reliability and effectiveness of your Ansible roles.
