我创建了一个头盔图，其secrets.yaml为：

apiVersion: v1
kind: Secret
type: Opaque
metadata: 
 name: appdbpassword
stringData:
  password: password@1

我的豆荚是：

apiVersion: v1
kind: pod
metadata:
  name: expense-pod-sample-1
spec:
  containers:
    - name: expense-container-sample-1
      image: exm:1
      command: [ "/bin/sh","-c","--" ]
      args: [ "while true; do sleep 30; done;" ]
      envFrom:
      - secretRef:
              name: appdbpassword

每当我运行kubectl get secrets命令时，都会得到以下秘密：

name                                     Type                 Data    Age
appdbpassword                            Opaque               1      41m
sh.helm.release.v1.myhelm-1572515128.v1  helm.sh/release.v1   1      41m

我为什么要得到这个额外的秘密？我在这里想念东西吗？
