Pick the difficulty that matches where you are. You can come back and try a harder level later.
Create a Basic CI Workflow
Write a GitHub Actions YAML file to automate testing and linting.
Multi-Environment Deployment Pipeline
Design a pipeline that deploys to Staging, then requires manual approval for Production.
Zero-Downtime Deployment Strategy
Architect a deployment process where users never see a 502 Bad Gateway.
CI/CD Pipeline Automation & Continuous Deployment
CI/CD automation guarantees that code changes are built, tested, and deployed reliably. DevOps leads look for experience with GitHub Actions / GitLab CI workflows, matrix test runners, Docker container registry builds, environment secrets, and zero-downtime deployments.
1. GitHub Actions Workflow Configuration
Production-ready .github/workflows/ci-cd.yml file defining linting, unit testing, container build, and deployment jobs.
2. Container Build & Test Script
Automated container build script compiling production images and running isolated test suites in ephemeral containers.
3. Deployment Verification & Rollback Log
Audit log documenting automated pipeline execution, deployment health checks, and rollback triggers.
Frequently Asked Questions (CI/CD Pipeline Setup)
What is matrix testing in CI/CD pipelines?
Matrix testing executes parallel pipeline jobs across multiple operating systems (Ubuntu, Windows) and language versions (Node 18, 20, 22) simultaneously.
How do you manage sensitive secrets in CI/CD pipelines?
Secrets should be stored in encrypted repository settings (e.g. GitHub Secrets or HashiCorp Vault) and injected into runner environments at build time.
What is zero-downtime deployment?
Zero-downtime deployment (like Blue-Green or Rolling deployments) routes traffic to new container versions only after health checks pass, preventing user disruption during updates.
