Vault Helm Tests

Running Vault Helm Acceptance tests

The Makefile at the top level of this repo contains a few target that should help with running acceptance tests in your own GKE instance or in a kind cluster.

Note that for the Vault Enterprise tests to pass, a VAULT_LICENSE_CI environment variable needs to be set to the contents of a valid Vault Enterprise license.

Running in a GKE cluster

Set the GOOGLE_CREDENTIALS and CLOUDSDK_CORE_PROJECT variables at the top of the file. GOOGLE_CREDENTIALS should contain the local path to your Google Cloud Platform account credentials in JSON format. CLOUDSDK_CORE_PROJECT should be set to the ID of your GCP project.
Run make test-image to create the docker image (with dependencies installed) that will be re-used in the below steps.
Run make test-provision to provision the GKE cluster using terraform.
Run make test-acceptance to run the acceptance tests in this already provisioned cluster.
You can choose to only run certain tests by setting the ACCEPTANCE_TESTS variable and re-running the above target.
Run make test-destroy when you have finished testing and want to tear-down and remove the cluster.

Running in a kind cluster

Run make test-acceptance LOCAL_ACCEPTANCE_TESTS=true
You can choose to only run certain tests by setting the ACCEPTANCE_TESTS variable and re-running the above target.
Run make delete-kind when you have finished testing and want to tear-down and remove the cluster.
You can set an alternate kind cluster name by specifying the KIND_CLUSTER_NAME variable for any of the above targets.
You can set an alternate K8S version by specifying the KIND_K8S_VERSION variable for any of the above targets.

See kind-quick-start if you don't have kind installed on your system.

Running chart verification tests

If chart-verifier is built and available in your PATH, run:

bats test/chart/verifier.bats

Or if you'd rather use the latest chart-verifier docker container, set USE_DOCKER:

USE_DOCKER=true bats test/chart/verifier.bats

Generating the values json schema

There is a make target for generating values.schema.json:

make values-schema

It relies on the helm schema-gen plugin. Note that some manual editing will be required, since several properties accept multiple data types.

Helm test

Vault Helm also contains a simple helm test under templates/tests/ that may be run against a helm release:

helm test <RELEASE_NAME>
