Open Source Project Canary Strategy In Deployment - 2025 Update

Canary deployment = release a new version to a SMALL % of users first.

If something goes wrong → delete canary instantly If all is good → scale canary up, scale v1 down

👉 No rollback needed 👉 No downtime 👉 This is why Canary exists

❌ No monitoring ❌ Canary has no readinessProbe ❌ Same DB migration for v1 & v2 ❌ Canary runs longer than needed ❌ No instant delete plan
