Ao criar um conjunto de nós regionais com gcloud. Os nós não se registram

Question

Ao executar o seguinte comando gcloud no meu cluster existente do GKE

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/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[@]}")

(Observe que isso é regional, portanto, usando o comando beta - suspeito que isso não aconteça com clusters não regionais) Eu recebo o seguinte erro:

    Creating node pool pool-alpha...done.

E, de fato, os nós são criados, mas não são registrados no cluster. Um bug com o GKE?

Foi um problema com minha linha --scopes $(printf ",%s" "${SCOPES[@]}") , que adicionava uma vírgula extra no final que (de forma compreensível) não é validada no gcloud cli e interrompe o processo interno de registro de nó do GKE

Eu mudei para --scopes $(IFS=','; echo "${SCOPES[*]}") (sem vírgula final) e agora funciona
