如何将所有Secrets中的所有值传递给Kuberentes中的env变量？

Question

我在Kubernetes中有多个秘密。它们全部包含许多值，例如：

apiVersion: v1
kind: Secret
metadata:
  name: paypal-secret
type: Opaque
data:
  PAYPAL_CLIENT_ID: base64_PP_client_id
  PAYPAL_SECRET: base64_pp_secret
stringData:
  PAYPAL_API: https://api.paypal.com/v1
  PAYPAL_HOST: api.paypal.com

我很好奇如何将所有值从所有Secrets传递到ReplicaSet例如。

我尝试了这种方法：

apiVersion: apps/v1
kind: ReplicaSet
metadata:
  name: pp-debts
  labels:
    environment: prod
spec:
  replicas: 1
  selector:
    matchLabels:
      environment: prod
  template:
    metadata:
      labels:
        environment: prod
    spec:
      containers:
      - name: integration-app
        image: my-container-image
        envFrom:
        - secretRef:
          name: intercom-secret
        envFrom:
        - secretRef:
            name: paypal-secret
        envFrom:
        - secretRef:
            name: postgres-secret
        envFrom:
        - secretRef:
            name: redis-secret

但是，当我连接到pod并查看env变量时，我只能从中看到值redis-secret。

尝试使用一个envFrom带有多个条目的条目，如下所示：

      - name: integration-app
        image: my-container-image
        envFrom:
        - secretRef:
            name: intercom-secret
        - secretRef:
            name: paypal-secret
        - secretRef:
            name: postgres-secret
        - secretRef:
            name: redis-secret
