fluentd 容器未通过 yaml (1.2) 安装 k8 worker 目录

Question

当我手动运行一个容器时，我看到了挂载，但是通过 yaml，挂载是空的。

apiVersion: v1
kind: Pod
metadata:
  name: fluentd2elasticsearch
  namespace: kube-system
spec:
  containers:
  - name: fluentd-es
    image: gcr.io/google_containers/fluentd-elasticsearch:1.15
    env:
      - name: FLUENTD_ARGS
        value: "-qq"
    volumeMounts:
      - name: containers
        mountPath: /var/lib/docker/containers
      - name: varlog
        mountPath: /var/log
  volumes:
  - name: containers
    source:
      hostDir:
        path: /var/lib/docker/containers
  - name: varlog
    source:
      hostDir:
        path: /var/log

当我连接到容器时，目录为空或仅包含 fluentd pod 文件。运行手动：

docker run -d -v /var/lib/docker/containers:/var/lib/docker/containers -v /var/log:/var/log gcr.io/google_containers/fluentd-elasticsearch:1.15

一切看起来都很棒，但我需要 kuber 来启动容器以使其与 elasticsearch 通信（在 kubernetes 或 k8 中，我有时看到写的）。

docker 检查显示：

"Mounts": [
    {
        "Source": "/var/lib/kubelet/pods/1c11495ddc980659911fd7a596a346f8/volumes/kubernetes.io~empty-dir/containers",
        "Destination": "/var/lib/docker/containers",
        "Mode": "",
        "RW": true
    },
    {
        "Source": "/var/lib/kubelet/pods/1c11495ddc980659911fd7a596a346f8/volumes/kubernetes.io~empty-dir/varlog",
        "Destination": "/var/log",
        "Mode": "",
        "RW": true
    },

我猜 kubernetes.io~empty-dir 不是我想在那里看到的。

卷部分似乎存在一些结构问题。尝试：

volumes:
  - name: containers
    hostPath:
      path: /var/lib/docker/containers
  - name: varlog
    hostPath:
      path: /var/log
