To remove a node from the cluster, use the rebalance command and specify the URI for the node you want to remove in the --server-remove option:

shell> couchbase-cli rebalance -c 10.4.2.4:8091 -u Administrator -p password --server-remove=10.4.2.4:8091

Additional servers can be specified by using addition --server-remove option. The operation imediately triggers s rebalance after the nodes have been removd from the cluster.
