After each node is up, you can make the final configuration. The way to set up the cluster in CouchDB is to add other CouchDB to a certain one through the admin http api.

$ curl -X PUT "http://admin:admin123@<IP>:5984/_node/_local/_nodes/couchdb@test_couchdb.2v2lb55cyes0rf3tbtqe2zp9x.strqjl8lsdm58tozn59mp8du7" -d {}
{"ok":true,"id":"couchdb@test_couchdb.2v2lb55cyes0rf3tbtqe2zp9x.strqjl8lsdm58tozn59mp8du7","rev":"1-967a00dff5e02add41819138abb3284d"}

$ curl -X PUT "http://admin:admin123@<IP>:5984/_node/_local/_nodes/couchdb@test_couchdb.7zj2xk3up7ce34atj2nme9rf9.u5ce5bl7cmjlhkb2781cye7py" -d {}
