ci-cd-gitlab-rails

What problem does it solve?

This Skill solves the common pain of misconfiguring GitLab CI/CD for Rails applications, which leads to slow pipelines, failed deployments, insecure credential storage, and wasted runner minutes due to missing caches, incorrect service setups, or unoptimized test sharding.

Core Features & Use Cases

• Full pipeline configuration: Provides production-ready patterns for build, test, security, and deploy stages tailored for Rails 8, including parallel RSpec execution, Rubocop linting, Brakeman security scanning, and Kamal deployment.
• Secure credential handling: Implements GitLab OIDC for cloud provider authentication instead of static long-lived keys, plus proper variable scoping for protected branches and production environments.
• Use Case: A Rails team using GitLab can use this Skill to generate a .gitlab-ci.yml that runs tests in parallel across 4 nodes, scans for vulnerabilities on every merge request, and requires manual approval before deploying to production on the main branch.

Quick Start

Use the ci-cd-gitlab-rails skill to generate a complete, production-ready .gitlab-ci.yml for your Rails 8 app on GitLab, with parallel test stages, security scans, and manual production deployment gates.
