configMap and secret - priority-CodePudding

I didn't find any information about priority of configMaps vs secrets. If I have the same keys in both, which one wins?

Here's an example of a template:

spec:
  containers:
  - envFrom:
    - configMapRef:
      name: my-configmap
    - secretRef:
      name: my-secret

CodePudding user response：

According to the kubernetes code, it iterates over the list in sequence.

func (b *ContainerApplyConfiguration) WithEnvFrom(values ...*EnvFromSourceApplyConfiguration) *ContainerApplyConfiguration {
    for i := range values {
.
.

So the order matters, whatever comes later in the list will overwrite the previous value. In the example you provided, the value from my-secret will win.
