"I’d use Jenkins or GitLab CI/CD to automate the deployment pipeline by defining a pipeline in a Jenkinsfile or .gitlab-ci.yml. The pipeline includes stages: code checkout from a Git repository, building the application (e.g., using Maven/Docker), running unit tests, and deploying to a staging environment. I’d configure webhooks for automatic triggers on code commits, use environment variables for secrets, and integrate tools like SonarQube for code quality. For production, I’d add approval gates and rollback mechanisms. Containers (Docker) and orchestrators (Kubernetes) ensure scalable, consistent deployments, with monitoring via Prometheus."
