使用 gcloud 創建區域節點池時。節點未註冊

gcloud在我現有的 GKE 集群上執行以下命令時

SCOPES=(
https://www.googleapis.com/auth/compute
https://www.googleapis.com/auth/devstorage.read_write
https://www.googleapis.com/auth/monitoring.write

)

gcloud beta container node-pools create $POOL_NAME \
--machine-type $MACHINE_TYPE \
--disk-size $DISK_SIZE \
--enable-autorepair \
--enable-autoscaling \
--min-nodes 1 --max-nodes 4 \
--cluster $CLUSTER \
--zone $ZONE \
--num-nodes 1 \
--scopes $(printf ",%s" "${SCOPES[@]}")

（注意這是區域性的，因此使用 beta 命令 - 我懷疑非區域性集群不會發生這種情況）我收到以下錯誤：

   Creating node pool pool-alpha...done.

實際上，節點已創建但未在集群上註冊。GKE 的錯誤？

Anton Kostenko 在 StackOverflow 上給出了答案：

https://stackoverflow.com/questions/49667351/when-creating-a-node-pool-multi-zone-with-gcloud-the-nodes-do-not-register-on

這是我的行的一個問題，--scopes $(printf ",%s" "${SCOPES[@]}")它在末尾添加了一個額外的逗號，這（有點可以理解）沒有在 gcloud cli 上驗證並破壞了一些內部 GKE 節點註冊過程

我將其更改為--scopes $(IFS=','; echo "${SCOPES[*]}")（沒有尾隨逗號），現在可以使用
