Improve Kubernetes Uptime and Resilience with a Canary Deployment - Seguridad Mania.com - España y América Latina

Your organization is successfully delivering apps in Kubernetes and now the team is ready to roll out v2 of a backend service. But there are concerns about traffic interruptions (a.k.a. downtime) and the possibility that v2 might unstable. As the Kubernetes engineer, you need to find a way to ensure v2 can be tested and rolled out with little to no impact to customers. You need to implement a gradual, controlled migration – and what better way than with the traffic splitting technique “canary deployment”! Canary deployments provide a safe and agile way to test the stability of a new feature or version. Because your use case involves traffic moving between two Kubernetes services, you know use of a service mesh will yield the easiest and most reliable results. You use NGINX Service Mesh to send 10% of your traffic to v2, which the remaining 90% to v1. Then you gradually transition larger percentages of traffic to v2 until you reach 100%. Problem solved! In This Lab You Will: ◆ Deploy minikube and NGINX Service Mesh ◆ Deploy two apps and use NGINX Service Mesh to observe traffic ◆ Use NGINX Service Mesh to implement a canary deployment Technologies Used: ◆ NGINX Service Mesh ◆ Helm ◆ Jaeger
