📄 Description

Added optional command and args overrides for the open-webui container and copy-app-data init container for use with custom images, etc.

Tested with minikube using the below values.yaml and custom open-webui image:

image:
  repository: open-webui-python
  tag: custom

copyAppData:
  command: ['sh', '-c', 'cp -R -n /usr/local/lib/python3.12/site-packages/open_webui/data/* /tmp/app-data/']

command:
  - python
args:
  - /app/scripts/open-webui-tls.py

volumeMounts:
  container:
    - name: open-webui-tls-entrypoint
      mountPath: /app/scripts
      readOnly: true
    - name: open-webui-tls-secret
      mountPath: /opt/ssl/open-webui
      readOnly: true
volumes:
  - name: open-webui-tls-entrypoint
    configMap:
      name: open-webui-tls-entrypoint
  - name: open-webui-tls-secret
    secret:
      secretName: openwebui-tls-secret
