Explain CI/CD for microservices.

Senior Microservices
Quick Answer CI/CD for microservices: each service has its own pipeline. On commit: run unit and integration tests, build Docker image, push to registry. On merge to main: deploy to staging, run contract and E2E tests, deploy to production via canary or blue-green. Use GitOps - desired state in Git, ArgoCD syncs cluster state. Independent pipelines = independent deployments.

Answer

CI automates build, tests, and validation for each commit.
CD automates deployment to staging/production.
Pipelines include unit tests, integration tests, linting, and security scans.
Tools include Jenkins, GitHub Actions, GitLab CI/CD, and Azure DevOps.
