Project history and usage

Conftest is an Open Policy Agent project for testing structured configuration data with Rego policies. It is commonly used to check Kubernetes manifests, Terraform, Tekton, Serverless configuration, and other machine-readable config before deployment.

Project history

The README and documentation describe Conftest as a utility for writing tests against structured configuration data and explicitly ground its policy language in Open Policy Agent's Rego. The project lives under the open-policy-agent GitHub organization and documents discussion in the OPA Slack #opa-conftest channel.

The documentation evolved from Kubernetes examples into a broader parser and policy-testing tool. It supports many formats including CUE, Dockerfile, HCL/HCL2, INI, JSON, Jsonnet, nginx, TOML, XML, YAML, CycloneDX, SPDX, and others, making it useful for policy-as-code checks across infrastructure repositories.

Adoption history

Conftest's adoption tracks the rise of policy-as-code in infrastructure delivery: it lets teams test configs locally, in CI, and through pre-commit before tools such as Kubernetes, Terraform, or deployment platforms consume them. Package-manager availability in Homebrew, Nix, Scoop, and zypper reflects that it is treated as a portable developer and CI binary.

How it is used

Typical usage is to place Rego files under a policy directory and run conftest test against one or more config files. The tool evaluates deny, violation, and warn rules in the main namespace by default, but supports namespace flags, stdin, metadata, unit tests with conftest verify, and parser builtins for policy tests.

Why package nerds care

For package curators, Conftest is notable because it packages OPA's policy engine into a focused CLI for files rather than services. It turns Rego from a runtime authorization language into a general-purpose config linting and testing binary that can sit cleanly in CI images and developer package sets.

Timeline

2025: release notes show ongoing OPA dependency updates and parser maintenance in the v0.62 line.
2026: v0.68.0 added an nginx parser and moved to OPA 1.15.1.
2026: v0.68.1 adjusted push behavior to use Rego v1 by default.
2026: v0.68.2 updated the embedded OPA dependency to 1.15.2.

Related projects

Official sources tie Conftest to Open Policy Agent, Rego, Kubernetes, Tekton, Terraform, Serverless, Dockerfile, HCL, Jsonnet, CUE, and pre-commit-style workflows.
