Design a CI/CD pipeline for a project: stages, tooling, deployment strategy, and GitHub Actions configuration

Containerize an application with Docker: write optimized Dockerfile, .dockerignore, and docker-compose for local dev

Write Terraform infrastructure code for cloud resources: compute, networking, databases, and IAM

CI/CD pipeline design with GitHub Actions: test stages, build, Docker image, deployment strategies, branch protection, and rollback. Use when designing or debugging a CI/CD pipeline.

Docker for Node.js applications: multi-stage Dockerfiles, layer caching, security hardening, docker-compose, and image optimization. Use when containerizing an application or debugging Docker issues.

Infrastructure as Code with Terraform: resource definitions, state management, modules, workspaces, and AWS/GCP patterns. Use when provisioning or modifying cloud infrastructure.

Kubernetes fundamentals for developers: Deployments, Services, ConfigMaps, Secrets, resource limits, health probes, HPA, and kubectl cheatsheet. Use when deploying or debugging an application on Kubernetes.

Monitoring and alerting for Node.js apps: Prometheus metrics, Grafana dashboards, CloudWatch, PagerDuty alerting, golden signals, and SLO-based alerting. Use when designing or improving observability.

Secrets management: AWS Secrets Manager, HashiCorp Vault, environment variable patterns, secret rotation, Kubernetes secrets, and detecting leaked secrets. Use when designing or auditing secret handling.
