How to configure docker-compose Kafka connect CDC setup with schema-registy?

Question

I am trying to set up docker-compose setup with

• Kafka broker
• zookeper
• debezium kafka connector
• schema-registry

using

• confluen kafka image
• debezium/connect:1.4
• confluent cp-schema-registry

Schema registry keeps giving error ... connection to node -1 (localhost/127.0.0.1:29092) could not be established...

Obviously trying to connect to localhost, but Kafka broker is in its own container in docker-compose setup.

I just cannot find any examples or documentation how to configure schema-registry.

All examples use config like:

      schema-registry:
        image: confluentinc/cp-schema-registry:5.5.3
        environment:
          - SCHEMA_REGISTRY_KAFKASTORE_CONNECTION_URL=zookeeper:2181
          - SCHEMA_REGISTRY_HOST_NAME=schema-registry
          - SCHEMA_REGISTRY_LISTENERS=http://schema-registry:8081,http://localhost:8081
        ports:
          - 8081:8081
        depends_on: [zookeeper, kafka]

ERROR Server died unexpectedly: (io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain) on kafkastore.bootrap.servers ...

schemaregisty.rest ???
