• Verify Multus Installation

  Once installed, verify that the Multus pod is running in the kube-system namespace:

  
  microk8s kubectl get pods -n kube-system

  Look for the multus pod. The pod should be in a Running state. If it is not, inspect the logs to troubleshoot:

  
  microk8s kubectl logs <multus-pod-name> -n kube-system

• 
  

  Modify NetworkAttachmentDefinition

  To use Multus, you will need to define additional networks for your pods. This is done by creating a NetworkAttachmentDefinition.

  Here's an example YAML file for our testbeamline it adds access to the gigavision network of our cameras:. 

  enp4s0f0 is the network interface that is connected with the cams
  rangeStart- rangeEnd are the address that the pod can acquire (note this addresses should not be assigned to HW)
  
  

  
  

  Code Block
  language yaml title Network attachement configuration
  apiVersion: k8s.cni.cncf.io/v1 kind: NetworkAttachmentDefinition metadata: name: gigevision-network namespace: testbeamline spec: config: '{ "cniVersion": "0.3.1", "type": "bridge", "master": "enp4s0f0", "bridge": "br0", "ipam": { "type": "host-local", "subnet": "192.168.115.0/24", "rangeStart": "192.168.115.220", "rangeEnd": "192.168.115.254", "routes": [ { "dst": "192.168.115.0/24", "gw": "192.168.115.2" } ], "gateway": "192.168.115.2" } }'

  
  

  
  

  
  

• Apply the NetworkAttachmentDefinition with:

  
  microk8s kubectl apply -f <filename>.yaml

• 
  

• Deploy Pods Using Multiple Networks

  After Multus is installed and your custom networks are defined, you can deploy pods with multiple network interfaces. Here's an example pod spec using two networks (one default and one from Multus):

  Code Block
  language yaml title Test gige camera access
  apiVersion: v1 kind: Pod metadata: name: pod-with-multus annotations: k8s.v1.cni.cncf.io/networks: gigevision-network spec: containers: - name: app-container image: https://baltig.infn.it/epics-containers/ioc-chart.git command: ["/bin/sh", "-c", "sleep 3600"]
