A canary deployment is a strategy where a new version of an application is released to a small subset of users before full deployment. To create an identical deployment for canary testing, follow these steps:
Duplicate the Deployment: Create a new deployment identical to the original, modifying the image tag for the new version.
Set Resource Limits: Adjust resource requests and limits to reflect the smaller scale of the canary.
Route Traffic: Use a service or ingress to route a small percentage of traffic to the canary while the majority continues to the stable version.
Monitor Performance: Implement monitoring tools like Prometheus or Grafana to track the canary's behavior.

Importance of Canary Deployment
Minimized Risk: Reduces impact on the entire system in case of a failure.
Quick Rollback: Simplifies reverting to the stable version if issues arise.
Real User Feedback: Validates performance and stability in real-world scenarios.
