Add Custom Volumes in Helm Installation

A Kubernetes volume is essentially a directory that is accessible to all the containers running in a pod. To configure custom volumes, use the customVolumes and customVolumeMounts sections for each product. Under these sections, you can create a volume configuration as it is, based on the official Kubernetes volume parameters.

Artifactory Example

In this example, we will use a configMap to mount as a custom volume, but you can use any supported Kubernetes volume:

To create a configMap called log-config that contains a test.yaml file, run the following command:
```
kubectl create configmap log-config --from-file=test.yaml
```

To create a custom volume, update the customVolumes section as follows:

artifactory:
  customVolumes: |
    - name: config-vol ## Name of the custom volume
      configMap: ## Predefined paramter of the configMap
        name: log-config

To define the mount path (/tmp/etc/) for the volume, update the customVolumeMounts section as follows:

artifactory:
  customVolumes: |
    - name: config-vol ## Name of the custom volume
      configMap: ## Predefined parameter of the configMap
        name: log-config

  customVolumeMounts: |
    - name: config-vol ## Name of the custom volume    
      mountPath: /tmp/etc/test.yaml
      subPath: test.yaml

These settings will bootstrap the configMap under the /tmp/etc folder. To further work with such custom volumes, use the preStartCommand and interact with them:

artifactory:
  customVolumes: |
    - name: config-vol
      configMap:
        name: log-config

  customVolumeMounts: |
    - name: config-vol ## The name here must match the name set under customVolumes    
      mountPath: /tmp/etc/test.yaml
      subPath: test.yaml
  preStartCommand: "cat /tmp/etc/test.yaml"

Follow the similar steps to manage custom volumes for Xray and Distribution. However, update the relevant configurations under the correct parent keys.

Xray Example

xray:
  common:
    customVolumes: |
      - name: config-vol
        configMap:
          name: log-config

    customVolumeMounts: |
      - name: config-vol ## The name here must match the name set under customVolumes    
        mountPath: /tmp/etc/test.yaml
        subPath: test.yaml
    preStartCommand: "cat /tmp/etc/test.yaml"

Distribution Example

distribution:
  common:
    customVolumes: |
      - name: config-vol
        configMap:
          name: log-config

    customVolumeMounts: |
      - name: config-vol ## The name here must match the name set under customVolumes    
        mountPath: /tmp/etc/test.yaml
        subPath: test.yaml
    preStartCommand: "cat /tmp/etc/test.yaml"
