A Canary Deployment involves rolling out the upgrade to a small subset of users before applying it across the entire cluster. This allows teams to detect and resolve issues before full deployment.
How It Works
-
Upgrade a small percentage of the Kubernetes nodes.
-
Monitor application performance and error rates.
-
If the upgrade is stable, gradually increase the rollout.
-
If issues arise, rollback without affecting the entire cluster.
Blue-Green Deployment: Zero-Downtime Upgrades
A Blue-Green Deployment involves running two identical environments (Blue & Green), where:
-
Blue represents the current live Kubernetes cluster.
-
Green is the new cluster with the upgraded Kubernetes version.
How It Works
-
Deploy the upgrade on the Green cluster while the Blue cluster remains live.
-
Run performance and security tests on the Green cluster.
-
If everything works correctly, redirect traffic to the Green cluster (making it the new live version).
-
If issues occur, instantly switch back to the Blue cluster without downtime.
3. Continuous Monitoring & Testing: Ensuring Stability Before Full Rollout
Upgrading Kubernetes isn’t just about applying the update—it’s about ensuring that the upgrade doesn’t break applications or infrastructure. Continuous monitoring and rigorous testing are essential to guarantee stability, performance, and security post-upgrade.
