启动AKS集群时,我的每个节点在/dev/sdb
上都有一个主磁盘,在/dev/sda
上有一个较小的临时磁盘。如何将其他未格式化的磁盘附加为/dev/sdc
到模板中的每个AKS节点。我当前的模板如下:

不幸的是,您似乎无法将磁盘添加到模板中的AKS节点。看一下template of AKS中的所有属性,没有属性可以做到这一点。
如果您确实要向节点添加磁盘,也许可以手动将磁盘附加到AKS群集中的VM。参见attach a data disk to a Linux VM。实际上,群集中的节点是Azure VM。因此,您可以像在Azure VM中一样进行操作。
但是,我认为,如果需要更多的磁盘空间,最好在创建AKS群集时为节点更改更大的大小。请参阅模板中有关osDiskSizeGB
和vmSize
的属性。您可以根据需要将持久卷添加到Pod。参见Manually create and use a volume with Azure disks in Azure Kubernetes Service (AKS),我认为以这种方式使用磁盘更加灵活和高效。

这是具有更多磁盘的节点的模板的外观:
{
"name": "nodepool1",
"count": 3,
"vmSize": "Standard_B2ms",
"osType": "Linux",
"osDiskSizeGB": 64,
"diskSizesGB": [
10,
10,
10,
10
]
}
不幸的是,尽管这是AKS的有效资源定义-尚无法使用,但至少在开始使用时,您将只使用此代码段;)
