You can now use Rook along with Multus. Multus must be up and running
and the right ressources must exist such as NetworkAttachmentDefinition
CR.
The Cluster CR spec has new fields to work with multus:
network:
provider: multus (or 'host' for hostNetworking)
selectors:
public: NetworkAttachmentDefinition name
cluster: NetworkAttachmentDefinition name
If only a single NetworkAttachmentDefinition is provided Rook will use
both anyway for the Ceph traffic.
Please refer to the doc to learn more.
Closes: https://github.com/rook/rook/issues/4716
