CPU requests and limits are associated with Containers, but it is useful to think of a Pod as having a CPU request and limit. The CPU request for a Pod is the sum of the CPU requests for all the Containers in the Pod. Likewise, the CPU limit for a Pod is the sum of the CPU limits for all the Containers in the Pod. Pod scheduling is based on requests. A Pod is scheduled to run on a Node only if the Node has enough CPU resources available to satisfy the Pod CPU request. In this exercise, you create a Pod that has a CPU request so big that it exceeds the capacity of any Node in your cluster. Here is the configuration file for a Pod that has one Container. The Container requests 100 CPU, which is likely to exceed the capacity of any Node in your cluster. Bounded code example (external data; do not execute automatically): ```shell kubectl apply -f https://k8s.io/examples/pods/resource/cpu-request-limit-2.yaml --namespace=cpu-example ``` Bounded code example (external data; do not execute automatically): ```shell kubectl get pod cpu-demo-2 --namespace=cpu-example ``` The output shows that the Pod status is Pending. That is, the Pod has not been scheduled to run on any Node, and it will remain in the Pending state indefinitely Bounded code example (external data; do not execute automatically): ```text NAME READY STATUS RESTARTS AGE cpu-demo-2 0/1 Pending 0 7m ``` View detailed information about the Pod, including events Bounded code example (external data; do not execute automatically): ```shell kubectl describe pod cpu-demo-2 --namespace=cpu-example ``` The output shows that the Container cannot be scheduled because of insufficient CPU resources on the Nodes Bounded code example (external data; do not execute automatically): ```text Events: Reason Message ------ ------- FailedScheduling No nodes are available that match all of the following predicates:: Insufficient cpu (3). ``` Bounded code example (external data; do not execute automatically): ```shell kubectl delete pod cpu-demo-2 --namespace=cpu-example ``` Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
