Schema Registry is designed to work as a distributed service using single master architecture, so at any given time there will be only one master and rest of the nodes refer back to it. You can refer the schema-registry arch here

You can choose 3 nodes schema-registry cluster (you can run on the same nodes along with zookeeper/Kafka), As you are using confluent 5.0, you can use the confluent CLI,

confluent start schema-registry 

Update the schema-registry.properties,

 #zookeeper urls
 kafkastore.connection.url=zookeeper-1:2181,zookeeper-2:2181,...
 #make every node eligible to become master for failover 
 master.eligibility=true

On the consumer and producer side, pass the list of schema-registry urls in the Consumer.props & Produce.props

props.put("schema.registry.url","http://schemaregistry-1:8081,http://schemaregistry-2:8081,http://schemaregistry-3:8081")

*By default schema-registry port will be 8081.

Hope this helps.
