CI/CD and Advanced Deployment

Create a basic Helm chart to package and deploy a Spring Boot microservice on Kubernetes.

Manage application releases using Helm commands, including install, upgrade, and rollback.

Design a CI/CD pipeline for a microservice, including build, test, containerize, and deploy stages.

Implement a CI/CD pipeline using Jenkins or GitLab CI to automatically deploy a microservice to Kubernetes.

Implement a blue-green deployment strategy using Kubernetes service selectors.

Implement a canary release strategy for a microservice using traffic splitting (e.g., with Ingress or a service mesh).

Describe strategies for handling database schema migrations in a zero-downtime deployment context (e.g., expand/contract pattern).

Implement feature flags within a Spring Boot application to decouple feature releases from deployments.
