Hi Phil,
Comments noted... When I finally see the data from "node" I will review and
go over with PO/Tech Lead (they built the Openshift Instances!).
Sadly I still dont know how, with the openshift-restclient-library, get to
the Node data.
I have tried every resource and every part of the API and although I can
see node in the object in the debugger as part of IResource objects, I
still canoot find how to access the node data.
I would have though I would be able to do something like:
Nodes nodes = client.getNodes();
for(Node eachNode : nodes) {
// dig into nodes....
}
Or.. in keeping (seemingly with how the library is built):
IRecource nodes = client.getResource(Resource.Nodes);
for(IResoruces eachNode : nodes) {
INode iNode = (INode)eachNode;
// dig into nodes....
}
At this rate I will have to start to use actual calls to the Openshift
instance (obtained from looking at loglevel=8 from oc calls below)...
Someone mentioned another library I could use to interrogate Openshift and
I will also go look at that to see if that allows access to Node
information.
Thx
