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 mount a configMap as a custom volume, but you can use any supported Kubernetes volume:

1. To create a configMap called log-config that contains a test.yaml file, run the following command:

   Bash

   kubectl create configmap log-config --from-file=test.yaml

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

   YAML

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

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

   YAML

   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

4. These settings will bootstrap the configMap under the /tmp/etc folder. To interact further with custom volumes, use the `preStartCommand:

   YAML

   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"
