#Custom Scheduler Base on Nodes Status

Running and testing the Custom Scheduler

1. Open 3 terminals
2. Terminal 1: kubectl proxy
3. Terminal 2:
   • go build . (from within the scheduler/ folder)
   • ./scheduler.
4. Terminal 3:
   • kubectl create -f deployments/testcustom.yaml
   • kubectl get pods -o wide (to see which node its been scheduled on; should be the 'best node' identified by the custom scheduler. See logs in Terminal 2 to verify)
