kubernetes集群节点多网卡，calico指定网卡

对于openstack 平台, 需要修改mtu 以及指定 网卡

 

1、calico如果有节点是多网卡，所以需要在配置文件中指定内网网卡

       - name: calico-node
          image: 172.16.230.97/source/node:v3.18.2
          envFrom:
          - configMapRef:
              # Allow KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT to be overridden for eBPF mode.
              name: kubernetes-services-endpoint
              optional: true
          env:
            # Use Kubernetes API as the backing datastore.
            - name: DATASTORE_TYPE
              value: "kubernetes"
            # DaemonSet 添加环境变量- name: IP_AUTODETECTION_METHOD
              value: "interface=ens192"
            # Wait for the datastore.
            - name: WAIT_FOR_DATASTORE
              value: "true"
            # Set based on the k8s node name.
