抛砖引玉，希望听听大家的解决方案。
我倾向于把 secret 放到 kubernetes secret
然后运行 pod 时，把各种 secret 通过环境变量（envFrom）注入到 pod 中。
apiVersion: v1
kind: Pod
metadata:
name: secret-test-pod
spec:
containers:
- name: test-container
image: registry.k8s.io/busybox
command: [ "/bin/sh", "-c", "env" ]
envFrom:
- secretRef:
name: mysecret
restartPolicy: Never
