This document explains how to create your custom values file for the ScalarDL Auditor chart. If you want to know the details of the parameters, please refer to the README of the ScalarDL Auditor chart.
Scalar Envoy configurations
You must set the Scalar Envoy configurations in the custom values file for ScalarDL Auditor. This is because client requests are sent to ScalarDL Auditor via Scalar Envoy as the load balancer of gRPC requests if you deploy ScalarDL Auditor on a Kubernetes environment.
Please refer to the document Configure a custom values file for Scalar Envoy for more details on the Scalar Envoy configurations.
You must set
auditor.image.repository. Be sure to specify the ScalarDL Auditor container image so that you can pull the image from the container repository.
If you’re using AWS or Azure, please refer to the following documents for more details:
- How to install Scalar products through AWS Marketplace
- How to install Scalar products through Azure Marketplace
You must set
auditor.auditorProperties. Please set your
auditor.properties to this parameter. Please refer to the auditor.properties for more details on the configuration of ScalarDL Auditor.
scalar.dl.auditor.ledger.host=<Host name to access ScalarDL Ledger pods>
You must set a private key file to
scalar.dl.auditor.private_key_path and a certificate file to
You must also mount the private key file and the certificate file on the ScalarDL Auditor pod.
For more details on how to mount the private key file and the certificate file, refer to Mount key and certificate files on a pod in ScalarDL Helm Charts.
Resource configurations (Recommended in the production environment)
If you want to control pod resources using the requests and limits of Kubernetes, you can use
Note that the resources for one pod of Scalar products are limited to 2vCPU / 4GB memory from the perspective of the commercial license. Also, when you get the pay-as-you-go containers provided from AWS Marketplace, you cannot run those containers with more than 2vCPU / 4GB memory configuration in the
resources.limits. When you exceed this limitation, pods are automatically stopped.
You can configure them using the same syntax as the requests and limits of Kubernetes. So, please refer to the official document Resource Management for Pods and Containers for more details on the requests and limits of Kubernetes.
If you want to use environment variables to set some properties (e.g., credentials) in the
auditor.auditorProperties, you can use
auditor.secretName to specify the Secret resource that includes some credentials.
For example, you can set credentials for a backend database (
scalar.db.password) using environment variables, which makes your pods more secure.
Please refer to the document How to use Secret resources to pass the credentials as the environment variables into the properties file for more details on how to use a Secret resource.
Affinity configurations (Recommended in the production environment)
If you want to control pod deployment using the affinity and anti-affinity of Kubernetes, you can use
You can configure them using the same syntax as the affinity of Kubernetes. So, please refer to the official document Assigning Pods to Nodes for more details on the affinity configuration of Kubernetes.
- key: app.kubernetes.io/name
- key: app.kubernetes.io/app
Prometheus/Grafana configurations (Recommended in the production environment)
If you want to monitor ScalarDL Auditor pods using kube-prometheus-stack, you can deploy a ConfigMap, a ServiceMonitor, and a PrometheusRule resource for kube-prometheus-stack using
SecurityContext configurations (Default value is recommended)
If you want to set SecurityContext and PodSecurityContext for ScalarDL Auditor pods, you can use
You can configure them using the same syntax as SecurityContext and PodSecurityContext of Kubernetes. So, please refer to the official document Configure a Security Context for a Pod or Container for more details on the SecurityContext and PodSecurityContext configurations of Kubernetes.
Replica configurations (Optional based on your environment)
You can specify the number of replicas (pods) of ScalarDL Auditor using
Logging configurations (Optional based on your environment)
If you want to change the log level of ScalarDL Auditor, you can use
Taint and toleration configurations (Optional based on your environment)
If you want to control pod deployment by using the taints and tolerations in Kubernetes, you can use
You can configure taints and tolerations by using the same syntax as the tolerations in Kubernetes. For details on configuring tolerations in Kubernetes, see the official Kubernetes documentation Taints and Tolerations.
