DevOps Engineering — Quick Reference
This skill equips teams with actionable templates, checklists, and patterns for building self-service platforms, automating infrastructure with GitOps, deploying securely with DevSecOps, scaling with Kubernetes, ensuring reliability through SRE practices, and operating production systems with strong observability.
Modern baseline (2026): IaC (Terraform/OpenTofu/Pulumi), GitOps (Argo CD/Flux), Kubernetes (follow upstream supported releases), OpenTelemetry + Prometheus/Grafana, supply-chain security (SBOM + signing + provenance), policy-as-code (OPA/Gatekeeper or Kyverno), and eBPF-powered networking/security/observability (e.g., Cilium + Tetragon).
Quick Reference
| Task | Tool/Framework | Command | When to Use |
|---|---|---|---|
| Infrastructure as Code | Terraform / OpenTofu | terraform plan && terraform apply |
Provision cloud resources declaratively |
| GitOps Deployment | Argo CD / Flux | argocd app sync myapp |
Continuous reconciliation, declarative deployments |
| Container Build | Docker Engine | docker build -t app:v1 . |
Package applications with dependencies |
| Kubernetes Deployment | kubectl / Helm (Kubernetes) | kubectl apply -f deploy.yaml / helm upgrade app ./chart |
Deploy to K8s cluster, manage releases |
| CI/CD Pipeline | GitHub Actions | Define workflow in .github/workflows/ci.yml |
Automated testing, building, deploying |
| Security Scanning | Trivy / Falco / Tetragon | trivy image myapp:latest |
Vulnerability scanning, runtime security, eBPF enforcement |
| Monitoring & Alerts | Prometheus + Grafana | Configure ServiceMonitor and AlertManager | Observability, SLO tracking, incident alerts |
