Rego policies related to the HACBS Enterprise Contract.

The Makefile contains a lot of useful scripts and commands. Run make by itself to see the help.

Three tools are required, conftest, opa, and gomplate.

You should be able to install them like this:

make install-tools

If that doesn't work, installing them manually and making sure they're available in your path should be fine.

An optional but useful tool for running tests while developing, (with make live-test), is entr. You can install it with dnf:

sudo dnf install entr

And of course you need make if you don't have it already:

sudo dnf install make

The rego files should be formatted using the standard format. To apply the standard format run this before committing:

make fmt

The documentation is built using Antora.

Those docs are published here and imported automatically into the official HACBS Documentation.

To build the documentation locally:

make docs-preview

From the top level directory you can run all tests and formatting checks, as well as check that the docs are up to date, like this:

make ci

You can run a single test like this:

opa test . -r <test_name_matcher>

The <test_name_matcher> is a regex, so you can use it to run more than one test.

See Makefile for other ways to run the tests.

Policies must have unit tests validating them. All test files must adhere to the naming convention:

file.rego
file_test.rego

Refer to the policy testing docs for more information.

The CI also enforces that there is 100% test coverage. If you're not at 100% you can use this to show what lines of code are not covered:

make coverage

Fetch an image attestation from a registry:

make fetch-att
more input/input.json # to look at it

or:

make fetch-att IMAGE=<some-image-with-an-attestation-ref>

Create a dummy policy config file:

make dummy-config
cat data/config.json # to look at it

Then to verify the build using the defined policies:

make check-release

For example to fetch a pipeline definition from your local cluster:

make fetch-pipeline
make fetch-pipeline PIPELINE=<some-pipeline-name>
more input/input.json # to look at it

For a realistic HACBS pipeline definition that does't require cluster access, if you you have the build-definitions repo checked out nearby you can do something like this:

( cd ../build-definitions && kustomize build pipelines/hacbs | yq 'select(document_index == 2)' -o json ) > input/input.json

Then to verify the pipeline definition using the defined policies:

make check-pipeline

The policies defined here are bundled and pushed as OCI artifacts using conftest. There are three bundles, one for each of the release and pipeline policies, and one for the data which is used by both.

The push-bundles automates creating and pushing these bundles to quay.io, and generating a related PR in the infra-deployments repo so the latest bundles are used.

See also the policy bundle documentation.

See the Policy Authoring documentation for guidance on contributing to the definition of policy rules.
