Creating a Resource Quota

Create a YAML file, for example, resource-quota.yaml, with the desired specifications for the Resource Quota.

apiVersion: v1
kind: ResourceQuota
metadata:
  name: compute-resources
  namespace: my-first-ns
spec:
  hard:
    pods: "4"
    requests.cpu: "1"
    requests.memory: 1Gi
    limits.cpu: "2"
    limits.memory: 2Gi

Apply the Resource Quota using the following command:

kubectl apply -f resource-quota.yaml

Verify Resource Quota Creation

To verify that the Resource Quota has been successfully created, run the following command:

kubectl get resourcequota compute-resources -n my-first-ns

View Existing Resource Quotas

To view the existing Resource Quotas in the my-first-ns namespace, use the following command:

kubectl get resourcequota -n my-first-ns

Delete a Resource Quota

To delete a Resource Quota from the my-first-ns namespace, execute the following command:

kubectl delete resourcequota compute-resources -n my-first-ns

Checking Resource Utilization

To check the resource utilization of the my-first-ns namespace, run the following command:

kubectl top namespace my-first-ns
