向现有集群添加新节点池失败,且没有节点注册。
添加node-pool的命令如下(项目名称已更改):
gcloud container --project my-project node-pools create hm-pool --cluster ds-cluster-west4 --zone europe-west4-c --node-version 1.16.9-gke.2 --machine-type n1-highmem-4 --image-type COS --disk-type pd-standard --disk-size 100 --metadata disable-legacy-endpoints=true --scopes logging-write,monitoring,pubsub,service-control,service-management,storage-full,taskqueue,trace --num-nodes 2 --enable-autoupgrade --enable-autorepair --max-surge-upgrade 1 --max-unavailable-upgrade 0
我收到以下错误消息
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.

在控制台上,我看到消息“自动修复节点池 hm-pool 中的节点。”并且我看到hm-pool
正在更新。池中有 0 个节点。
我究竟做错了什么?
答案1
问题是,新节点池的规范中缺少应用于集群的标签。我从现有节点之一中提取了标签信息,gcloud compute instances describe --format="value[delimiter=','](tags.items) INSTANCE-NAME
并将输出用作--tags
node-pools create 命令选项的参数。然后成功创建了节点池。
