有没有办法将JSON文件直接加载到kubernetes环境变量或configmap中？

apiVersion: v1
kind: ConfigMap
metadata:
  name: my-configmap
data:
  my-config.json: |
    {
      "key1": "value1",
      "key2": "value2"
    }

kubectl apply -f ConfigMap.yaml

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
spec:
  containers:
    - name: my-container
      image: my-image
      env:
        - name: MY_CONFIG
          valueFrom:
            configMapKeyRef:
              name: my-configmap
              key: my-config.json
  ...

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
spec:
  containers:
    - name: my-container
      image: my-image
      volumeMounts:
        - name: config-volume
          mountPath: /path/to/config
  volumes:
    - name: config-volume
      configMap:
        name: my-configmap
  ...
