在Google App Engine中使用Golang连接到Aerospike DB(来自Google云)

I installed Aerospike using oneclick installer from google cloud.

I am trying to connect to aerospike from Golang(gin gonic) using aerospike-client-go like this:

    client, err := NewClient("ip", 3000) #I tried all three types of
    #urls localhost, internal ip, external ip but nothing worked.

I read in another SO question that we should connect to GCE rather than aerospike. I didnt understand. If that is the answer, can you please tell me how ?
