How reproducible:

always

Steps to Reproduce:
1. fresh fedora/centos atomic host
2. deploy secret (kubectl create -f secret.json)

secret.json:

{
  "apiVersion": "v1",
  "kind": "Secret",
  "metadata" : {
    "name": "test-secret"
  },
  "type": "Opaque",
  "data": {
    "test-data":"dGVzdDEyMw=="
  }
}

3. deploy pod (kubectl create -f test-pod.yaml)

test-pod.yaml:

apiVersion: v1
kind: Pod
metadata:
  name: test-pod
spec:
  containers:
  - name: test
    image: busybox
    volumeMounts:
    - name: "test-volume"
      mountPath: "/test"
      readOnly: true
    command: ["sh"]
    args: ["-c 'ls -l /test/test-data; cat /test/test-data'"]

  volumes:
    - name: "test-volume"
      secret:
        secretName: "test-secret"


Actual results:

output:

-bash-4.2# kubectl logs test-pod
ls: cannot access /test/test-data: Permission denied
total 0
-????????? ? ? ? ?            ? test-data
cat: /test/test-data: Permission denied


Expected results:

output:

-bash-4.2# kubectl logs test-pod
total 4
-r--r--r--. 1 root root 7 Oct 15 08:08 test-data
test123


Additional info:

After disabling SELinux (setenforce 0) the secret is accessible.
