I apologize, but the knowledge sources provided do not contain specific information about installing Oathkeeper via Helm on Kubernetes or about the

oathkeeper-rules-volume

issue you're experiencing. The available information is more general and doesn't address your particular setup or error. However, I can provide some general guidance based on the available information: 1. Ory does offer Helm charts for Kubernetes deployment. According to the [Oathkeeper Installation documentation](https://www.ory.sh/docs/oathkeeper/install#kubernetes), you can find available Helm charts at k8s.ory.sh/helm. 2. The configuration of access rules in Oathkeeper is typically done through repositories, which can be files, environment variables, or HTTP(s) remotes. This is mentioned in the [API Access Rules documentation](https://www.ory.sh/docs/oathkeeper/api-access-rules). 3. In a production environment, it's recommended to separate configuration values from the build artifact. The documentation suggests that for Kubernetes, it would make sense to provide JSON Web Keys as a Kubernetes Secret mounted in a directory. Given that your specific issue isn't covered in the provided knowledge sources, I would recommend: 1. Checking the official Ory Helm charts documentation for any specific instructions on setting up the rules volume. 2. Ensuring that you've properly configured the access rules repository in your Helm values. 3. Considering whether you need to mount a volume for your rules, possibly as a ConfigMap or Secret. If these steps don't resolve your issue, you might want to reach out to the Ory community on their [Slack channel](http://slack.ory.sh/) or check their GitHub repository for similar issues or to open a new one.
