Kustomize makes Kubernetes manifest management tractable. It does not make it safe. Overlays can silently remove resource limits, merge in insecure defaults, or produce structurally invalid YAML that only breaks at apply time. Testing Kustomize configurations before kubectl apply means catching those failures in CI—not during an incident. The

Compliance frameworks like CIS Benchmarks contain hundreds of controls. Auditing them manually—or trusting that your IaC applied them correctly—is a recipe for drift. InSpec turns benchmark requirements into executable tests that run after provisioning and on a schedule. Here's how to go beyond the sample profiles

The basics of Atlantis—comment atlantis plan on a PR, review the plan, apply—are well documented. What's less covered is how to enforce policy at plan time, build reusable workflow components, and test your Atlantis configuration before it breaks a production PR. This post goes deep on

Spacelift sits between Atlantis (self-hosted, minimal) and Terraform Cloud (SaaS, opinionated). It handles Terraform, Pulumi, Ansible, and CloudFormation from a single platform. But its differentiating features—OPA-based policies, drift detection, and stack dependency graphs—require deliberate configuration to be useful. Here's how to build a tested,

Basic Molecule usage—spin up a Docker container, run a playbook, verify with Ansible—covers maybe 30% of real-world scenarios. When your roles provision multiple nodes, interact with cloud APIs, or require OS-specific behavior, you need the advanced toolkit. This guide covers multi-instance testing, the delegated driver,
