使用 gcloud 创建区域节点池时。节点不会注册

gcloud在我现有的 GKE 集群上运行以下命令时

SCOPES=(

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[@]}")

（请注意，这是区域性的，因此使用 beta 命令 - 我怀疑这不会发生在非区域集群中）我收到以下错误：

    Creating node pool pool-alpha...done.

确实，节点已创建但未在集群上注册。GKE 有错误吗？

Anton Kostenko 在 StackOverflow 上给出了答案：

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

我的这行代码有问题--scopes $(printf ",%s" "${SCOPES[@]}")，在末尾多加了一个逗号，而这个逗号（有点可以理解）在 gcloud cli 上没有得到验证，并且破坏了一些内部 GKE 节点注册过程

我将其改为--scopes $(IFS=','; echo "${SCOPES[*]}")（没有尾随逗号），现在它可以工作了
