VLAN External Network in Openshift using NMState Operators and Multus
NMstate operators and Multus CNI provide us with plugins and APIs, to set up external network in openshift container ecosystem. Let us see how we can implement a external VLAN networking for certain pods/VMs apart from, pods/VMs using internal cluster networking. When we install NMState operator, it avails us 3 different APIs, namely: Node Network Configuration Policy : Node level network settings implementation. # oc get nncp Node Network State : The current state of node network is stored in this. # oc get nns/<node-name> Node Network Configuration Enactment : The status of NNCP implementation across cluster nodes, is checked in this object. # oc get nnce Network Attachment Definition (NAD) : Apart from above APIs, we will also make use of NAD from multus CNI plugin framework. This implements namespaced object that exposes existing layer 2 network dev...
