Config Validator Policy Library
Bundles | Templates | Sample Constraints
This repo contains a library of constraint templates and sample constraints.
For information on setting up Config Validator to secure your environment, see the User Guide.
Initializing a policy library
You can easily set up a new (local) policy library by downloading a bundle using kpt.
Download the full policy library and install the Forseti bundle:
export BUNDLE=forseti-security
kpt pkg get https://github.com/GoogleCloudPlatform/policy-library.git ./policy-library
kpt fn source policy-library/samples/ | \
kpt fn eval - --image gcr.io/config-validator/get-policy-bundle:latest -- bundle=$BUNDLE | \
kpt fn sink policy-library/policies/constraints/$BUNDLE
Once you have initialized a library, you might want to save it to git.
Developing a Constraint
If this library doesn't contain a constraint that matches your use case, you can develop a new one using the Constraint Template Authoring Guide.
Available Commands
make audit Run audit against real CAI dump data
make build Format and build
make build_templates Inline Rego rules into constraint templates
make debug Show debugging output from OPA
make format Format Rego rules
make help Prints help for targets with comments
make test Test constraint templates via OPA
Inlining
You can run make build to automatically inline Rego rules into your constraint templates.
This is done by finding a INLINE("filename") and #ENDINLINE statements in your yaml,
and replacing everything in between with the contents of the file.
For example, running make build would replace the raw content with the replaced content below
Raw:
#INLINE("my_rule.rego")
# This text will be replaced
#ENDINLINE
Replaced:
#INLINE("my_rule.rego")
#contents of my_rule.rego
#ENDINLINE
Linting Policies
Config Validator provides a policy linter. You can invoke it as:
go get github.com/GoogleCloudPlatform/config-validator/cmd/policy-tool
policy-tool --policies ./policies --policies ./samples --libs ./lib
Local CI
You can run the cloudbuild CI locally as follows:
gcloud components install cloud-build-local
cloud-build-local --config ./cloudbuild.yaml --dryrun=false .
Updating CI Images
You can update the CI images to add new versions of rego/opa as they are released.
# Rebuild all images.
make -j ci-images
# Rebuild a single image
make ci-image-v1.16.0
