Chapter 9 ■ Scheduling Pods on NodesFigure 9-55. Adding another-annotation-key: another-annotation-valueDelete the with-label pod and create the pod again as shown in Figure 9-56. The pod is againscheduled on the node with the label kubernetes.io/image-name: nginx.Figure 9-56. Scheduling a pod with node affinityThe node affinity preferredDuringSchedulingIgnoredDuringExecution is only a hint. To demonstratethat, set all the options for the kubernetes.io/image-name label key to hello-world, both in the Inexpression and in the another annotation as shown in Figure 9-57.233
Chapter 9 ■ Scheduling Pods on NodesFigure 9-57. Setting all label values to nginxDelete and create the pod again. The pod is scheduled on the node with kubernetes.io/image-name label key set to hello-world, as shown in Figure 9-58. Again the schedulerdoes not guarantee pod allocation to a node with the specified labels when the node affinity ispreferredDuringSchedulingIgnoredDuringExecution. With the same settings, the pod could just as wellhave been allocated to a different node.Figure 9-58. Scheduling a pod with node affinity preferredDuringSchedulingIgnoredDuringExecutiondoes not guarantee pod schedulement on a particular nodeAs another example, specify all the kubernetes.io/image-name key values to those not used in nodelabels, as shown in Figure 9-59.234
