Conftest Helm plugin
Install the plugin using the built-in plugin manager.
helm plugin install https://github.com/instrumenta/helm-conftest
Assuming you have policy defined in the
policy folder, you can point the plugin at your chart.
$ helm conftest . FAIL - release-name-mysql must include Kubernetes recommended labels: https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/#labels Error: plugin "conftest" exited with error
Conftest has a number of flags which can alter it's behaviour, from changing the output formatting to
specifying where to find the policy files. Conftest options are automatically passed to Conftest,
with any other options being passed to Helm in the same way as
helm template. This means you
could set values before validating the chart. eg.
helm conftest charts/stable/nginx-ingress --set controller.image.tag=latest
