我正在尝试将以下两个标志添加到 /etc/kubernetes/manifests/kube-apiserver.yaml 文件中的 apiserver:

spec:
   containers:
   - command:
     - kube-apiserver
     - --enable-admission-plugins=NodeRestriction,PodNodeSelector
     - --admission-control-config-file=/vagrant/admission-control.yaml

[...]

我没有为 /vagrant/admission-control.yaml 文件安装卷或安装点。它完全可以从节点主节点访问,因为它由 vagrant 创建的 VM 共享:

vagrant@master-1:~$ cat /vagrant/admission-control.yaml 
apiVersion: apiserver.config.k8s.io/v1
kind: AdmissionConfiguration
plugins:
- name: PodNodeSelector
  path: /vagrant/podnodeselector.yaml
vagrant@master-1:~$

Kubernetes 版本:

vagrant@master-1:~$ kubectl version

Client Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.0", GitCommit:"cb303e613a121a29364f75cc67d3d580833a7479", GitTreeState:"clean", BuildDate:"2021-04-08T16:31:21Z", GoVersion:"go1.16.1", Compiler:"gc", Platform:"linux/amd64"}

Server Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.0", GitCommit:"cb303e613a121a29364f75cc67d3d580833a7479", GitTreeState:"clean", BuildDate:"2021-04-08T16:25:06Z", GoVersion:"go1.16.1", Compiler:"gc", Platform:"linux/amd64"}

链接到正在运行的集群正在使用的 /etc/kubernetes/manifests/kube-apiserver.yaml 文件这里

vagrant@master-1:~$ kubectl delete pods kube-apiserver-master-1 -n kube-system

pod "kube-apiserver-master-1" deleted

不幸的是,“kubectl describe pods kube-apiserver-master-1 -n kube-system”仅告知该 pod 已重新创建。标志未按需要显示。没有报告错误。

任何建议都会有所帮助,

谢谢你。

笔记:

  1. 我还尝试在 apiserver 的 configmap 上打一个补丁。补丁已应用,但不会在新运行的 Pod 中生效。
  2. 我还尝试通过 kubeadm init --config 在一个文件中传递这两个标志,但是关于如何将这两个标志以及我需要的所有其他 apiserver 的所有其他标志放在配置文件中以便重新安装的文档很少主节点。

更新:

我希望这对面临同样问题的每个人都有用......

经过 2 天的互联网搜索和大量测试后,我只能通过以下程序使其工作:

sudo tee ${KUBEADM_INIT_CONFIG_FILE} <<EOF
apiVersion: kubeadm.k8s.io/v1beta2
kind: InitConfiguration
localAPIEndpoint:
  advertiseAddress: "${INTERNAL_IP}"
  bindPort: 6443
---
apiVersion: kubeadm.k8s.io/v1beta2
kind: ClusterConfiguration
kubernetesVersion: ${KUBERNETES_VERSION}
controlPlaneEndpoint: "${LOADBALANCER_ADDRESS}:6443"
networking:
  podSubnet: "10.244.0.0/16"
apiServer:
  extraArgs:
    advertise-address: ${INTERNAL_IP}
    enable-admission-plugins: NodeRestriction,PodNodeSelector
    admission-control-config-file: ${ADMISSION_CONTROL_CONFIG_FILE}
  extraVolumes:
    - name: admission-file
      hostPath: ${ADMISSION_CONTROL_CONFIG_FILE}
      mountPath: ${ADMISSION_CONTROL_CONFIG_FILE}
      readOnly: true
    - name: podnodeselector-file
      hostPath: ${PODNODESELECTOR_CONFIG_FILE}
      mountPath: ${PODNODESELECTOR_CONFIG_FILE}
      readOnly: true
EOF


sudo kubeadm init phase control-plane apiserver --config=${KUBEADM_INIT_CONFIG_FILE}

您需要创建hostPath如下所示的卷挂载

volumeMounts:
- mountPath: /vagrant
  name: admission
  readOnly: true
...
volumes:
- hostPath:
    path: /vagrant
    type: DirectoryOrCreate
  name: admission
