尝试应用 Calico 节点配置时，如何修复“无法应用‘Node’资源：[更新冲突：Node(...)]”？

我正在使用 Kubernetes，有两台 VirtualBox 机器 - 主服务器和工作服务器。每台机器都有两个网络接口 - 一个用于 Internet，另一个用于虚拟机和主机之间的通信。我在设置 Calico 时遇到了麻烦，因为它会自动检测错误的网络接口。我做了一些设置来修复它，但还有一个问题 - 工作服务器使用了错误的 IP。我找到了修复方法 - 但它不起作用。详情如下。

当前工作者配置是（10.0.3.15那些是“错误的”IP）：

[12:35]user@ubuntu-vbox-k8s-master[~]$ ./calicoctl get node ubuntu-vbox-k8s-worker -o yaml
apiVersion: projectcalico.org/v3
kind: Node
metadata:
  annotations:
    projectcalico.org/kube-labels: '{"beta.kubernetes.io/arch":"amd64","beta.kubernetes.io/os":"linux","kubernetes.io/arch":"amd64","kubernetes.io/hostname":"ubuntu-vbox-k8s-worker","kubernetes.io/os":"linux"}'

    kubernetes.io/os: linux
  name: ubuntu-vbox-k8s-worker
  resourceVersion: "9219"
  uid: 6f5efd41-e06c-4f9d-9b3a-248af88a385e
spec:

    type: CalicoNodeIP
  - address: 10.0.3.15
    type: InternalIP
  bgp:
    ipv4Address: 10.0.3.15/24
    ipv4IPIPTunnelAddr: 192.168.77.64
  orchRefs:
  - nodeName: ubuntu-vbox-k8s-worker
    orchestrator: k8s
status: {}

我尝试应用固定的一个：

[12:37]user@ubuntu-vbox-k8s-master[~]$ cat calico-worker.yaml 
apiVersion: projectcalico.org/v3
kind: Node
metadata:
  annotations:
    projectcalico.org/kube-labels: '{"beta.kubernetes.io/arch":"amd64","beta.kubernetes.io/os":"linux","kubernetes.io/arch":"amd64","kubernetes.io/hostname":"ubuntu-vbox-k8s-worker","kubernetes.io/os":"linux"}'
  creationTimestamp: "2021-09-26T10:59:00Z"
  labels:
    beta.kubernetes.io/arch: amd64
    beta.kubernetes.io/os: linux
    kubernetes.io/arch: amd64
    kubernetes.io/hostname: ubuntu-vbox-k8s-worker
    kubernetes.io/os: linux
  name: ubuntu-vbox-k8s-worker
  resourceVersion: "5303"
  uid: 6f5efd41-e06c-4f9d-9b3a-248af88a385e
spec:
  addresses:
  - address: 192.168.56.109
    type: InternalIP
  orchRefs:
  - nodeName: ubuntu-vbox-k8s-worker
    orchestrator: k8s
status: {}

出现错误：

[12:38]user@ubuntu-vbox-k8s-master[~]$ ./calicoctl apply -f calico-worker.yaml 
Failed to apply 'Node' resource: [update conflict: Node(ubuntu-vbox-k8s-worker)]

这很奇怪，因为我成功地以相同的方式修复了 Calico 主节点，而没有与配置冲突：

    projectcalico.org/kube-labels: '{"beta.kubernetes.io/arch":"amd64","beta.kubernetes.io/os":"linux","kubernetes.io/arch":"amd64","kubernetes.io/hostname":"ubuntu-vbox-k8s-master","kubernetes.io/os":"linux","node-role.kubernetes.io/control-plane":"","node-role.kubernetes.io/master":"","node.kubernetes.io/exclude-from-external-load-balancers":""}'

答案1

kubectl set env daemonset/calico-node -n kube-system IP_AUTODETECTION_METHOD=interface=enp0s3通过Calico Slack 频道的命令解决了https://docs.projectcalico.org/networking/ip-autodetection
