Question

在我现有的GKE集群上运行以下gcloud命令时

SCOPES=(
https://www.googleapis.com/auth/compute
https://www.googleapis.com/auth/devstorage.read_write
https://www.googleapis.com/auth/monitoring.write
https://www.googleapis.com/auth/logging.write
https://www.googleapis.com/auth/monitoring
https://www.googleapis.com/auth/pubsub
https://www.googleapis.com/auth/servicecontrol
https://www.googleapis.com/auth/service.management
https://www.googleapis.com/auth/sqlservice.admin
https://www.googleapis.com/auth/trace.append
https://www.googleapis.com/auth/cloud_debugger
https://www.googleapis.com/auth/cloud-platform
)

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[@]}")

（注意这是区域性的，所以使用beta命令 - 我怀疑非区域集群不会发生这种情况）我收到以下错误：

    Creating node pool pool-alpha...done.

实际上，节点已创建但未在群集上注册。 GKE有错误吗？

我重现了你的情况，但看起来这不是GKE问题。

我认为问题出现在$(printf ",%s" "${SCOPES[@]}")函数中，该函数从逗号开始创建列表，并以某种方式影响可用范围。

我还发现https://www.googleapis.com/auth/cloud_debugger不在node-pools create命令的可用范围的list中。但是，基于云调试器documentation，您可以使用cloud-platform范围而不是cloud_debugger，一切都会正常。

所以，我用手动添加的范围检查了命令，它运行正常：

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 logging-write,monitoring-write,service-management,compute-rw,storage-rw,monitoring,pubsub,service-acontrol,service-management,sql-admin,trace,cloud-platform

使用gcloud创建节点池（多区域）时，节点不会在kubernetes主节点上注册
