Chapter 10 ■ Configuring Compute Resources
The number of pod replicas has a limit, as the per-node resource capacity could start to be approached
with more replicas. With the previous settings seven replicas are scheduled, as shown in Figure 10-16. One of
the nodes has three pods.
Figure 10-16. Kubernetes cluster capacity has a limit, allowing seven pods to be scheduled on three nodes in
this example
Describe the node with the three pods, and you’ll see that resource consumption is at 90% for both CPU
and memory, as shown in Figure 10-17. No more pods can be scheduled on the pod.

The minimum memory limit allowed is 4 MB.
