Usalo CreateCluster con un o AWS SDK CLI

L' ParametersThis esempio Create a Cluster with Minimal crea un cluster con il set minimo di parametri. Per impostazione predefinita, l'output è in JSON formato.Comando:

aws redshift create-cluster --node-type dw.hs1.xlarge --number-of-nodes 2 --master-username adminuser --master-user-password TopSecret1 --cluster-identifier mycluster

Risultato:
