在 GKE 中使用 N2 机器类型 - (Google Kubernetes Engine)

Question

我正在尝试创建一个基于单个节点的集群，该节点的机器类型为n2-highcpu-2，位置europe-west3-a。在创建节点时，我收到以下错误消息：

区域配额不足以满足请求：资源“N2_CPUS”： 请求需要'2.0'并且是简短的'2.0'。该项目的配额为 '0.0' 和 '0.0' 可用。查看和管理配额 https://console.cloud.google.com/iam-admin/quotas?usage=USED&project=gordion-project.

我正在通过配额页面请求增加配额（请参阅下面的附录 1）。 后来我总是从谷歌收到以下邮件，我无法增加配额：

你好， 我们试图调整您项目的配额：gordion-project 但是 没有发现任何需要进行的更改。这可能是由于 无法完成部分请求。如果你想 减少您的配额，请回复此消息并支持 代表会尽快与您联系。如果当前值仍然 不足，请提出减少要求的新请求或 额外的理由。要验证当前配额，请导航至 https://console.cloud.google.com/iam-admin/quotas?project=xx-xx .

最好的问候和快乐的计算！

此致，云平台支持

我还能做些什么来创建具有 n2 机器类型的集群？

我在 CLI 中运行了命令：gcloud container clusters create "test-cluster-1" --zone "europe-west1-b" --machine-type "n2-highcpu-2"

得到以下输出：

WARNING: In June 2019, node auto-upgrade will be enabled by default for newly created clusters and node pools. To disable it, use the `--no-enable-autoupgrade` flag.
WARNING: Starting in 1.12, new clusters will have basic authentication disabled by default. Basic authentication can be enabled (or disabled) manually using the `--[no-]enable-basic-auth` flag.

此错误表示您在该特定区域遇到临时资源缺货问题 europe-west3-a。我已经尝试按照您在我的项目中的步骤进行操作，但我遇到了同样的错误。

推荐的解决方法是尝试不同的区域或稍后检查该特定区域。查看文档Regions and Zones 并尝试其他区域。

我快速检查了一些区域，例如europe-west1-b、europe-west1-c、europe-west2-a、europe-west2-c、europe-west4-a、europe-west4-b、europe-west4-c，没有发现任何问题：

$ gcloud container clusters create "test-cluster-1" --zone "europe-west4-a" --machine-type "n2-highcpu-2" 
WARNING: Currently VPC-native is not the default mode during cluster creation. In the future, this will become the default mode and can be disabled using `--no-enable-ip-alias` flag. Use `--[no-]enable-ip-alias` flag to suppress this warning.
WARNING: Newly created clusters and node-pools will have node auto-upgrade enabled by default. This can be disabled using the `--no-enable-autoupgrade` flag.
WARNING: Starting with version 1.18, clusters will have shielded GKE nodes by default.
WARNING: Your Pod address range (`--cluster-ipv4-cidr`) can accommodate at most 1008 node(s). 
This will enable the autorepair feature for nodes. Please see https://cloud.google.com/kubernetes-engine/docs/node-auto-repair for more information on node autorepairs.

我能够使用我当前的配额运行我的测试。

更新测试区域europe-west1-b：

$ gcloud container clusters create "test-cluster-1" --zone "europe-west1-b" --machine-type "n2-highcpu-2"
WARNING: Currently VPC-native is not the default mode during cluster creation. In the future, this will become the default mode and can be disabled using `--no-enable-ip-alias` flag. Use `--[no-]enable-ip-alias` flag to suppress this warning.

UPDATE2查看错误信息：

ERROR: (gcloud.container.clusters.create) ResponseError: code=403, message=Insufficient regional quota to satisfy request: resource "N2_CPUS": request requires '6.0' and is short '6.0'. project has a quota of '0.0' with '0.0' available. View and manage quotas at https://console.cloud.google.com/iam-admin/quotas?usage=USED&project=gordion-project.

您的问题的主要原因是Insufficient regional quota to satisfy request: resource "N2_CPUS"。再次尝试request an increase in quota，如果您会得到相同的回复，请联系Google Cloud Support。
