kubernetes - kubernetes 中的 OutOfcpu 错误是什么意思？

Question

我在 googlecloud 上的 kubernetes 中得到了 OutOfcpu，这是什么意思？我的 pod 现在似乎可以正常工作，但是在同一个版本中有一些 pod 出现了 OutOfcpu。

Answer 1

意思是kube-scheduler找不到任何具有可用 CPU 的节点来安排您的 pod:

kube-scheduler selects a node for the pod in a 2-step operation:

1. Filtering
2. Scoring

The filtering step finds the set of Nodes where it’s feasible to schedule the Pod. For example, the PodFitsResources filter checks whether a candidate Node has enough available resource to meet a Pod’s specific resource requests.
[...]
PodFitsResources: Checks if the Node has free resources (eg, CPU and Memory) to meet the requirement of the Pod.

此外，根据 Assigning Pods to Nodes :

If the named node does not have the resources to accommodate the pod, the pod will fail and its reason will indicate why, e.g. OutOfmemory or OutOfcpu.
