I’m using the Helm chart to deploy Odoo to Kubernetes in EKS.
I’m search how to add new volume (persistent volume) with my odoo pod?
This is my last update of my values.yaml:

## @param extraVolumes Optionally specify extra list of additional volumes for Odoo pods
##
extraVolumes: 
  - name: python-data
    emptyDir: {}
## @param extraVolumeMounts Optionally specify extra list of additional volumeMounts for Odoo container(s)
##
extraVolumeMounts:
  - name: python-data
    mountPath: /opt/bitnami/python
