 Launch CouchDB container and name it 'fullsync'
 
 ```console
-$ docker run -d --name fullsync couchdb:1.7.1
+$ docker run -d --name fullsync couchdb:2.3.0
 ```
 
 Then launch Convertigo and link it to the running 'fullsync' container. Convertigo MBaaS sever will automatically use it as its fullsync repository.
