The subnet for the interface ens192 on the cluster nodes here is 10.6.0.0/16. The subnet for the interface ens193 on the cluster nodes here is 10.7.0.0/16. Create SpiderIPPools using these subnets:

$ cat <<EOF | kubectl apply -f -

Create an application

1. Add the same annotation to the application:

   ...
   spec:
     template:
       metadata:
         annotations:
           cni.spidernet.io/network-resource-inject: multi-network
   

   Note: When using the webhook automatic injection of network resources feature, do not add other network configuration annotations (such as k8s.v1.cni.cncf.io/networks and ipam.spidernet.io/ippools) to the application, as it will affect the automatic injection of resources.

2. Once the Pod is created, you can observe that the Pod has been automatically injected with network card annotations.

   ...
   spec:
     template:
       metadata:
         annotations:
             k8s.v1.cni.cncf.io/networks: |-
               [{"name":"macvlan-ens192","namespace":"spiderpool"},
               {"name":"macvlan-ens193","namespace":"spiderpool"}]
        ....
