CI/CD pipelines break over one overlooked discipline. Here's how we made ours 🛡️ bulletproof by mastering SNAPSHOT vs. RELEASE versions.
This is the philosophy behind our dev-to-prod workflow, and why it's non-negotiable:
🚧 The SNAPSHOT Stage:
This isn't just a build. It's the "draft" state where we accept instability 🌪️. The key is to contain it. By deploying SNAPSHOTs only to dev/test, we ensure chaos never reaches production. It's a sandbox for innovation 🧪.
✅ The RELEASE Promotion:
This is where we create a single source of truth 🥇. Promoting an artifact to an immutable RELEASE in Nexus guarantees that what was tested is exactly what gets deployed. No more "it worked on my machine"! It's traceable, auditable, and production-ready.
🚦 The Production Rule:
The golden rule is simple: production only ever sees immutable RELEASE artifacts 🚀. This practice alone prevents 90% of deployment issues. We use Canary 🐤 or Blue/Green 🔵 rollouts as a final safety net 🥅 for our users.
⏪ The Rollback Discipline:
A successful pipeline isn't just about pushing forward; it's about how fast you can move back ↩️🔄. Our rollback mechanism ensures an incident is measured in minutes, not hours, protecting the team and the user ❤️.
This is a strategic framework for managing risk 📊, building trust 🤝, and sleeping soundly on release nights 😴.
