问题描述

我正在尝试使用Kubernetes DaemonSets，一点都没有运气.我一直在寻找无济于事的解决方案.我希望这里有人可以帮忙.

I'm trying to get going with Kubernetes DaemonSets and not having any luck at all. I've searched for a solution to no avail. I'm hoping someone here can help out.

首先，我看过此票证.重新启动控制器管理器似乎无济于事.如您在这里看到的，其他的kube进程都在apiserver之后启动，并且api服务器设置为'--runtime-config = extensions/v1beta1 = true'.

First, I've seen this ticket. Restarting the controller manager doesn't appear to help. As you can see here, the other kube processes have all been started after the apiserver and the api server has '--runtime-config=extensions/v1beta1=true' set.

kube     31398     1  0 08:54 ?        00:00:37 /usr/bin/kube-apiserver --logtostderr=true --v=0 --etcd_servers=http://dock-admin:2379 --address=0.0.0.0 --allow-privileged=false --portal_net=10.254.0.0/16 --admission_control=NamespaceAutoProvision,LimitRanger,ResourceQuota --runtime-config=extensions/v1beta1=true
kube     12976     1  0 09:49 ?        00:00:28 /usr/bin/kube-controller-manager --logtostderr=true --v=0 --master=http://127.0.0.1:8080 --cloud-provider=
kube     29489     1  0 11:34 ?        00:00:00 /usr/bin/kube-scheduler --logtostderr=true --v=0 --master=http://127.0.0.1:8080

但是api版本仅显示版本1:

However api-versions only shows version 1:

$ kubectl api-versions
Available Server Api Versions: v1

Kubernetes版本为1.2:

Kubernetes version is 1.2:

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.0", GitCommit:"86327329213fed4af2661c5ae1e92f9956b24f55", GitTreeState:"clean"}
Server Version: version.Info{Major:"1", Minor:"2", GitVersion:"v1.2.0", GitCommit:"86327329213fed4af2661c5ae1e92f9956b24f55", GitTreeState:"clean"}

DaemonSet已创建，但似乎没有计划的Pod(status.desiredNumberScheduled).

The DaemonSet has been created, but appears to have no pods scheduled (status.desiredNumberScheduled).

$ kubectl get ds -o json
{
    "kind": "List",
    "apiVersion": "v1",
    "metadata": {},
    "items": [
        {
            "kind": "DaemonSet",
            "apiVersion": "extensions/v1beta1",
            "metadata": {
                "name": "ds-test",

                    "app": "ds-test"
                }
            },
            "spec": {
                "selector": {
                    "app": "ds-test"

                "template": {
                    "metadata": {
                        "creationTimestamp": null,
                        "labels": {
                            "app": "ds-test"
                        }
                    },
                    "spec": {
                        "containers": [
                            {
                                "name": "ds-test",
                                "image": "foo.vt.edu:1102/dbaa-app:v0.10-dvlp",
                                "ports": [
                                    {
                                        "containerPort": 8080,
                                        "protocol": "TCP"
                                    }
                                ],
                                "resources": {},
                                "terminationMessagePath": "/dev/termination-log",
                                "imagePullPolicy": "IfNotPresent"
                            }
                        ],
                        "restartPolicy": "Always",
                        "terminationGracePeriodSeconds": 30,
                        "dnsPolicy": "ClusterFirst",
                        "securityContext": {}
                    }
                }
            },
            "status": {
                "currentNumberScheduled": 0,
                "numberMisscheduled": 0,
                "desiredNumberScheduled": 0
            }
        }
    ]
}

这是我的yaml文件，用于创建DaemonSet

Here is my yaml file to create the DaemonSet

apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
  name: ds-test
spec:
  selector:
    app: ds-test
  template:
    metadata:
      labels:
        app: ds-test
    spec:
      containers:
      - name: ds-test
        image: foo.vt.edu:1102/dbaa-app:v0.10-dvlp
        ports:
          - containerPort: 8080

使用该文件创建DaemonSet似乎可以正常工作(我得到了创建的daemonset"ds-test")，但是没有创建任何pod:

Using that file to create the DaemonSet appears to work (I get 'daemonset "ds-test" created'), but no pods are created:

$ kubectl get pods -o json
{
    "kind": "List",
    "apiVersion": "v1",
    "metadata": {},
    "items": []
}

DaemonSet

daemonset不创建任何Pod
