Validate an Ansible Role with Molecule Tests

Problem/Feature Description

A platform team has developed an Ansible role called nginx-proxy that sets up nginx as a reverse proxy. The role includes a Molecule test suite for local testing. A new team member is preparing to submit this role to the team's shared role library, and needs a full quality validation pass before submitting.

The role's molecule test environment uses Docker. Perform a complete validation of the role, documenting what you ran and in what order. If any environment blockers prevent molecule tests from running, document the blocker clearly but continue with all other validation steps.

Your report should give the reviewer enough information to make a go/no-go decision on accepting the role into the shared library.

Output Specification

Produce validation_report.md documenting the full validation with all steps, findings, and a final recommendation.
