Mount ExistingClaim in Logstash install with Helm

Elastic Stack Logstash
#1

I am using the official Helm chart for Logstash.
I want to mount a volume using an existingClaim that has some dictionaries that will be used for translate filters across multiple Logstash instances.

How do I bring in the PVC I created called dictionary and have it mounted into
/usr/share/logstash/config/dic ?

Figured it out using the Extras using either a configmap or a PVC persistentVolumeClaim. It was hard to find specific examples of this so here is what works.

persistence:
  enabled: false
  annotations: {}

extraVolumeMounts:
  - name: list
    mountPath: "/usr/share/logstash/config/listings.yaml"
    subPath: listings.yaml
    readOnly: true
  - name: dictionary
    mountPath: "/usr/share/logstash/config/dictionary"
    readOnly: true
extraVolumes:
  - name: list
    configMap:
      name: listings
  - name: dictionary
    persistentVolumeClaim:
      claimName: dictionary

You can also use the secretMount for a file in some cases.

secretMounts:
  - name: querytemplate
    secretName: querytemplate
    path: /usr/share/logstash/config/scripts
