Policy as Code: OPA, Sentinel, tfsec

This generated surface maps a learner-facing curriculum unit to its canonical source routes.

Curriculum surface​

  • Open learner-facing unit
  • Curriculum path: content/curriculum/production/semester-09-cloud-devops/module-02-infrastructure-as-code/concepts/cluster-05-iac-beyond-terraform/15-policy-as-code-opa-sentinel-tfsec-primary.md
  • App: production
  • Semester: semester-09-cloud-devops
  • Module: module-02-infrastructure-as-code
  • Unit kind: concept
  • Curation level: module_curated

Learning objectives​

  • Explain Policy as Code: OPA, Sentinel, tfsec as a repeatability, reviewability, and drift-control problem instead of just writing configuration files.
  • Use Policy as Code: OPA, Sentinel, tfsec to reason about safe change, environment consistency, and the cost of unmanaged infrastructure state.
  • Use git-from-the-bottom-up, pro-git, the-linux-command-line to connect the learner page to provisioning workflows, state management, policy, and operational recovery paths.

Prerequisites​

  • Comfort with cloud platform primitives and the idea that infrastructure should be repeatable, reviewable, and recoverable.
