📋 Containers & IaC Cheat Sheet

Container strategies and infrastructure as code patterns for AZ-400.

Containers

  • Multi-stage Docker builds: build stage compiles; runtime stage has minimal image.
  • ACR Tasks: automated image builds triggered by code commits or base image updates.
  • Helm charts: templated Kubernetes manifests with values.yaml overrides.
  • Image scanning: integrate Trivy or Defender for Containers in CI pipelines.

Infrastructure as Code

  • Bicep: DSL for ARM templates with modules, parameters, and what-if preview.
  • Terraform: multi-cloud IaC with state management and plan/apply workflow.
  • Desired State Configuration (DSC): enforce VM configuration compliance.
  • IaC in pipelines: validate → plan → apply with manual approval gates.
