azure - azure kubernetes 集群的垂直扩展

Question

我无法垂直扩展我的 AKS 集群。目前，我的集群中有 3 个节点，2 个核心和 8 个 RAM，我正在尝试将其升级为 16 个代码和 64 个 RAM，我该怎么做？我尝试缩放 VM 规模集，在 Azure 门户上它显示它已缩放，但当我执行“kubectl getnodes -o Wide”时，它仍然显示旧版本。

任何线索都会有帮助。谢谢，阿布舍克

不支持垂直扩展或更改节点池虚拟机大小。您需要创建一个新的节点池并在新节点上调度您的 Pod。

this UX issues is due to how the VMSS is managed by AKS. Since AKS isa managed service, we don't support operations done outside of the AKSAPI to the infrastructure resources. In this example you are using theVMSS portal to resize, which uses VMSS APIs to resize the resource andas a result has unexpected changes.

AKS nodepools don't support resize in place, so the supported way todo this is to create a new nodepool with a new target and delete theprevious one. This needs to be done through the AKS portal UX. Thismaintains the goal state of the AKS node pool, as at the moment theportal is showing the VMSize AKS knows you have because that is whatwas originally requested.
