Currently, the local workflow is far from optimal, since for every change on the multus images the developers are required to redeploy the kind cluster. A more efficient workflow would be to build a local image, upload it to the kind cluster, and finally re-deploy (delete & re-provision) the daemonset, which would be running the new version. For this flow to be possible, the multus container `imagePullPolicy` must be set to `Always` - [0] - otherwise, the image is not updated.
