Kubernetes(1.10)mountproduction:双向不工作。

我正在创建一个将volumemount设置为 mountPropagation: Bidirectional 。创建后,容器将用 "Propagation": "rprivate" .

来自K8 docs 我希望 装载传播:双向 导致卷装入传播 rshared

如果我直接用 docker 这是有效的。

一些信息:

部署yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: test
spec:
  selector:
    matchLabels:
      app: test
  strategy:
    type: RollingUpdate
  template:
    metadata:
      labels:
        app: test
    spec:
      containers:
      - image: gcr.io/google_containers/busybox:1.24
        command:
          - sleep
          - "36000"
        name: test
        volumeMounts:
        - mountPath: /tmp/test
          mountPropagation: Bidirectional
          name: test-vol
      volumes:
      - name: test-vol
        hostPath:
          path: /tmp/test

生成的安装部分来自 docker inspect

"Mounts": [
            {
                "Type": "bind",
                "Source": "/tmp/test",
                "Destination": "/tmp/test",
                "Mode": "",
                "RW": true,
                "Propagation": "rprivate"
            }…..

等效Docker运行

docker run --restart=always --name test -d --net=host --privileged=true -v /tmp/test:/tmp/test:shared gcr.io/google_containers/busybox:1.24

生成的mounts部分来自 码头工人检查 创建时使用 docker run

"Mounts": [
            {
                "Type": "bind",
                "Source": "/tmp/test",
                "Destination": "/tmp/test",
                "Mode": "shared",
                "RW": true,
                "Propagation": "shared"
            }...
