• Take me to Practice Test

Solutions to practice test - multiple schedulers

• Run the command ‘kubectl get pods –namespace=kube-system’

  ``` $ kubectl get pods --namespace=kube-system ```

• Run the command ‘kubectl describe pod kube-scheduler-controlplane –namespace=kube-system’

  ``` $ kubectl describe pod kube-scheduler-controlplane --namespace=kube-system ```

• Use the imperative command to create the configmap with option –from-file

  ``` $ kubectl create -n kube-system configmap my-scheduler-config --from-file=/root/my-scheduler-config.yaml ```

• Use the file at /root/my-scheduler.yaml to create your own scheduler with correct image.

  ``` $ kubectl create -f /root/my-scheduler.yaml ```

• Set schedulerName property on pod specification to the name of the new scheduler. File is located at /root/nginx-pod.yaml

  ``` master $ grep schedulerName /root/nginx-pod.yaml schedulerName: my-scheduler $ kubectl create -f /root/nginx-pod.yaml ```
