Managing Infra

Infrastructure patterns for Kubernetes, Terraform, Helm, Kustomize, and GitHub Actions. Use when making K8s architectural decisions, choosing between Helm vs Kustomize, structuring Terraform modules, writing CI/CD workflows, or applying security best practices.

Infrastructure Patterns

When to Use What

Tool	Use For
Raw K8s YAML	Simple deployments, one-off resources
Kustomize	Environment variations, overlays without templating
Helm	Complex apps, third-party charts, heavy templating
Terraform	Cloud resources, infrastructure lifecycle
GitHub Actions	CI/CD, automated testing, releases
Makefile	Build automation, self-documenting targets
Dockerfile	Container builds, multi-stage, multi-arch

Quick Decisions

Kustomize when: Simple env differences, readable manifests, patching YAML Helm when: Complex templating, third-party charts, release management

K8s Security Defaults

Every workload: non-root user, read-only filesystem, no privilege escalation, dropped capabilities, network policies.

GitHub Actions Patterns

CI workflow: Lint, test, compile on PRs (run on both x86 + ARM)
Release workflow: Multi-arch Docker build on tags (native ARM runners)
Pin actions by SHA, least-privilege permissions
