嗨，我在运行Kafka连接码头图片

docker run -d \
  --name=kafka-connect \
  --net=host \
  -e CONNECT_BOOTSTRAP_SERVERS=localhost:39092 \
  -e CONNECT_REST_PORT=28082 \
  -e CONNECT_GROUP_ID="quickstart" \
  -e CONNECT_CONFIG_STORAGE_TOPIC="quickstart-config" \
  -e CONNECT_OFFSET_STORAGE_TOPIC="quickstart-offsets" \
  -e CONNECT_STATUS_STORAGE_TOPIC="quickstart-status" \
  -e CONNECT_KEY_CONVERTER="io.confluent.connect.avro.AvroConverter" \
  -e CONNECT_KEY_CONVERTER_SCHEMA_REGISTRY_URL="http://localhost:8081" \
  -e CONNECT_VALUE_CONVERTER="io.confluent.connect.avro.AvroConverter" \
  -e CONNECT_VALUE_CONVERTER_SCHEMA_REGISTRY_URL="http://localhost:8081" \
  -e CONNECT_INTERNAL_KEY_CONVERTER="io.confluent.connect.avro.AvroConverter" \
  -e CONNECT_INTERNAL_VALUE_CONVERTER="io.confluent.connect.avro.AvroConverter" \
  -e CONNECT_REST_ADVERTISED_HOST_NAME="localhost" \
  -e CONNECT_ZOOKEEPER_CONNECT="localhost:2181" \
  tim/kafka-connect

以及获得

Exception in thread "main" org.apache.kafka.common.config.ConfigException: Missing Schema registry url!
    at io.confluent.connect.avro.AvroConverter.configure(AvroConverter.java:64)
    at org.apache.kafka.connect.runtime.Worker.<init>(Worker.java:93)
    at org.apache.kafka.connect.cli.ConnectDistributed.main(ConnectDistributed.java:74)

无法确定在何处添加“schema.registry.url”conf！！
