You add a new node with the at the RESTful endpoint host:port/controller/addNode. You will need to provide an administrative username and password as parameters:

shell> curl -u Administrator:password \
    10.2.2.60:8091/controller/addNode \
    -d "hostname=10.2.2.64&user=Administrator&password=password"

Here we create a request to add a new node to the cluster at 10.2.2.60:8091 by using method, controller/addNode and by providing the IP address for the new node as well as credentials. If successful, Couchbase Server will respond:

Status Code 200 OK
      {"otpNode":"ns_1@10.4.2.6"}
