kubernetes 中的 calico + multus 静态 ip 配置

编程问答 2022-07-28

问题描述

我正在尝试使用静态 IP 配置我的 Pod。发现你可以用 multus 做到这一点。我的主要 cni 是 calico，一些示例配置如下：

kind: PersistentVolumeClaim
apiVersion: v1
Metadata:
  name: dnsmasqconf-pv1
  namespace: vt
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  storageClassName: ceph-rbd-sc
---
apiVersion: apps/v1
kind: Deployment
Metadata:
  name: dnsmasq1
  annotations:
    k8s.v1.cni.cncf.io/networks: vt/macvlan
#     "cni.projectcalico.org/ipAddrs": "[\"192.168.0.131\"]"
  namespace: vt
  labels:
    name: dnsmasq1
#  podIP: 192.168.0.131
spec:
#  serviceName: "dnsmasq1"
  replicas: 1
  selector:
    matchLabels:
      name: dnsmasq1
  template:
    Metadata:
      labels:
        name: dnsmasq1
    spec:
      hostNetwork: false
      affinity:
        podAntiAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
          - labelSelector:
              matchLabels:
                name: dnsmasq1
            topologyKey: "kubernetes.io/hostname"
      hostname: dnsmasq1
      containers:
      - name: dnsmasq1
        image: jpillora/dnsmasq
        ports:
        - containerPort: 8080
        imagePullPolicy: IfNotPresent
        env:
        - name: HTTP_USER
          value: "user"
        - name: HTTP_PASS
          value: "password"
        volumeMounts:
        - mountPath: /mnt/config
          name: dnsmasqconf-pv1
      nodeselector:
        etiket: worker
      dnsPolicy: "None"
      dnsConfig:
        nameservers:
          - 8.8.8.8
      volumes:
      - name: dnsmasqconf-pv1
        persistentVolumeClaim:
          claimName: dnsmasqconf-pv1

名为“vt/macvlan”的注解如下：

apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDeFinition
Metadata:
  name: macvlan
  namespace: vt
spec:
  config: '{
            "cniVersion": "0.3.1","type": "macvlan","master": "eth0","mode": "bridge","ipam": {
                "type": "host-local","ranges": [
                    [ {
                         "subnet": "192.168.0.0/24","rangeStart": "192.168.0.131","rangeEnd": "192.168.0.131","gateway": "192.168.0.7"
                    } ]
                ]
            }
        }'

我也试过这样的：

apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDeFinition
Metadata:
  name: eth0
  namespace: vt
spec:
  config: '{
      "cniVersion": "0.3.1","master": "ens18","ipam": {
        "type": "multus","subnet": "192.168.0.0/24","routes": [
          { "dst": "0.0.0.0/0" }
        ],"gateway": "192.168.0.7"
      }
    }'

但是无论配置如何，pod 都不是使用指定的 ip 创建的。我需要尽快解决这个问题。我该怎么做？
