Branch-Based CI/CD: Quality Gate to Multi-Environment Deploy with GitHub Actions

This article presents a reusable GitHub Actions pattern for branch-based CI/CD, integrating SonarQube quality gates, Docker builds, image scanning, and SSH deployments across dev, staging, and production. It highlights common pitfalls like workflow_run trigger failures and offers a single reusable workflow with per-environment secrets and approval gates. The approach aims to reduce drift and duplication compared to separate deploy files per environment.
