在AWS中使用boto創建羣集Reshift

Question

obj = boto.redshift.layer1.RedshiftConnection() 
obj.create_cluster(
    cluster_identifier='bototest', 
    node_type='dw.hsl.xlarge', 
    master_username='suresh', 
    master_user_password='Suresh123', 
    db_name='dev', 
    cluster_type='single-node', 
    cluster_security_groups='None', 
    vpc_security_group_ids='None', 
    cluster_subnet_group_name='None', 
    availability_zone='us-east-1', 
    preferred_maintenance_window='None', 
    cluster_parameter_group_name='None', 
    automated_snapshot_retention_period='None', 
    port=5439, 
    cluster_version='None', 
    allow_version_upgrade='None', 
    number_of_nodes=1, 
    publicly_accessible='None', 
    encrypted='None') 

爲什麼我得到這個錯誤？

Answer 1

參數allow_version_upgrade，publicly_accessible，和encrypted期望bool值，無論是True或False。您正在傳遞一個包含值None的字符串。另外，對於cluster_version，您還傳遞一個包含值None而非特殊常量None的字符串。

create_cluster方法的聯機文檔非常完整。你可以在這裏找到它們：http://docs.pythonboto.org/en/latest/ref/redshift.html#boto.redshift.layer1.RedshiftConnection.create_cluster。
