🚀 CI/CD Pipeline Build & Test (Episode 2) A CI/CD pipeline passed… but the application was completely broken. This is one of the most dangerous mistakes in DevOps. In this video, we build a real CI pipeline using GitHub Actions, Docker, and application testing — and expose a critical issue most tutorials ignore. 🔥 What you’ll learn: - How to build a real CI pipeline (not just basic YAML) - Docker build and run inside CI/CD - Why pipelines can give false confidence - Fake tests vs real validation - How to properly validate applications in CI - Why retry logic and health checks matter - Real DevOps debugging workflow 💣 Real takeaway: A pipeline that passes doesn’t mean your system works. --- 🛠️ Tech used: - GitHub Actions - Docker - Flask app --- 📂 Full project: 👉 Comment “CI/CD” — I’ll share the repo --- ⚠️ This is not a basic tutorial. This is how CI/CD behaves in real production systems. --- 📈 If this helped: Like 👍 Comment “CI/CD” Share with someone learning DevOps 📈 If you’re serious about DevOps: Subscribe and follow the full series. Because most pipelines don’t fail in development… they fail in production.
