Node Selector Feature

[imanless]

Is it possible to define a certain worker node for each lab node in the topology file, meaning one can choose which worker node should the lab node be deployed on, instead of relying on the kubernetes default scheduler?

This is not something we have explored. Although I could see that being very useful for cases when you have a topo with some nodes requiring nested virt support and only some worker nodes that supported nested virt for example.

This may not be too difficult to add using the existing labels field:

kne/proto/topo.proto

Line 70 in b5d7825

map<string, string> labels = 4; // Metadata labels describing the node.

which get applied to the pod:

kne/topo/node/node.go

Line 453 in b5d7825

pod.ObjectMeta.Labels[label] = v
