How can i rename a helm chart once created?

Question

I have created a helm chart named "abc" with the command helm create abc Now when I install this chart, all the kuberenets resources created will have a name containing "abc".

Now I have to rename the chart "abc" to "xyz". If i use helm install --name xyz ./abc only the chart name is changed to xyz. The resources inside it remain with "abc".

I need to rename the entire chart (with its resources) to be renamed. Do I have any option for it?

You can access xyz with {{ .Release.Name }} and need to update the resource names with {{ .Release.Name }} so that the names are picked up dynamically every time:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Release.Name }}
  labels:
    app.kubernetes.io/name: {{ .Values.app.dbName }}
    app.kubernetes.io/instance: {{ .Release.Name }}
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/name: {{ .Values.app.dbName }}
      app.kubernetes.io/instance: {{ .Release.Name }}
  template:
    metadata:
      labels:
        app.kubernetes.io/name: {{ .Values.app.dbName }}
        app.kubernetes.io/instance: {{ .Release.Name }}
    spec:
      containers:
        - image: mysql:5.6
          name: "{{ .Release.Name }}-mysql" // or just {{ .Release.Name }}
