Karbon：自定义Kube-let保留记忆

Karbon总是为Kube-LET和其他节点资源分配400MB。但是，这并不总是足够的，当系统正在加载时，kube-let可能会过时。

当Kube-let用尽内存，然后我们将吊舱滞留在“终止”状态下，我们必须重新启动节点。我所期望的是Kube-LET终止的豆荚，这些豆荚没有记忆，而kube-let不会用完记忆。

典型的1-1.4MB保留在其他Kubernetes簇中的16GB内存的节点（EKS/AKS/GKE/...）中保留。

也可以看看

https://kubernetes.io/docs/tasks/administers-cluster/Reserve-Compute-Resources/

目前，我们添加了额外的节点，并希望我们不会在任何节点上变得过时。但是，这不是Kubernetes设计的。

有什么可调整400MB固定尺寸预订的工作吗？

Hello @eriklund<\/user-mention>\u00a0<\/p>

For the moment there is no official supported way to modify this settings, but there is improvements already targeted in the roadmap to mitigate resource reservation problem. In the meantime please open a support ticket to track your problem precisely. Stay tuned and thanks for your support.<\/p>","className":"post__content__best_answer"}">

Karbon always allocates 400MB\u00a0for kube-let and other node resources. However, this is not always enough and kube-let can run out-of-memory when system is under load.<\/p>

When kube-let runs out of memory then we get pods stranded in \u201cTerminating\u201d state and we have to reboot the node. What I did expect was the kube-let terminated pods that got out-of-memory and that kube-let would not run out of memory.<\/p>

Typical 1-1.4MB are reserved at nodes with 16GB memory in other Kubernetes clusters (EKS\/AKS\/GKE\/...)<\/p>

https:\/\/kubernetes.io\/docs\/tasks\/administer-cluster\/reserve-compute-resources\/<\/a><\/p>

Currently we have added extra nodes and hope that we will not get out-of-memory on any nodes. However, that is not what\u00a0Kubernetes is\u00a0designed.<\/p>

\u00a0<\/p>

Any work-a-round for adjusting the 400MB fixed size reservation?<\/p>","quoteUsername":"eriklund","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
