Helm chart supports using namespaceOverride.

[ace0527]

Currently, the namespace attribute value of all namespace-related components in the templates is namespace: {{ .Release.Namespace }}, making it impossible to use namespaceOverride in dependencies to define the namespace.
A more flexible and compatible implementation should be as follows:
Add a template:

{{- define "local-path-provider.namespace" -}}
{{- if .Values.namespaceOverride }}
{{- .Values.namespaceOverride }}
{{- else }}
{{- .Release.Namespace }}
{{- end }}
{{- end -}}

Assign the namespace to the component:

namespace: {{ include "phpmyadmin.namespace" . }}

Currently, to modify the namespace, you can only pull the dependency locally and modify the code.
I hope future versions can be compatible with namespaceOverride.
