3. 在物理机上面查看pod 的cgroup中设置的内存限制,因为,我们没有进行限制,所以默认为pod 的内存大小,其中128974848=123Mi (123*1024*1024). 注意:一旦pod中使用的内存大小超过123Mi,那么cgroup就会kill 里面的进程 cd /sys/fs/cgroup/memory/kubepods/burstable/podbc001ffa-68fc-11e9-92d7-5ef9efd9374c ...

applying cgroup … caused: mkdir …no space left on device或者在 describe pod 的时候出现 cannot allocate memory。这时候你的 k8s 集群可能就存在内存泄露的问题了,当创建的 pod 越多的时候内存会泄露的越多,越快。具体查看是否存在内存泄露$ cat /sys/fs/cgroup/memory/kubepods/memory.kmem.slabinfo当...

(kube_pod_container_resource_limits{resource="cpu"})) > 0.8 Kubernetes CPU限制 CPU Throttling是一种当进程即将达到某些资源限制时减慢进程的行为,与内存的情况类似,这些限制可能是: 在容器上设置的Kubernetes Limit。 在命名空间上设置的Kubernetes ResourceQuota。
k8s cgroup memory限制查看 k8s磁盘限制 前言: 学习参考kubernetes官方文档,以kubernetes为准 pod是容器的集合,容器中的隐患(cpu、IO、MEM),在k8s中依然存在 官方文档:https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/
