apache-kafka - 使用 Avro 转换器运行 Kafka Connect : ConfigException: "Missing Schema registry url"

Question

您好，我正在运行 Kafka Connect docker 图像

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

得到

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)

不知道在哪里添加“schema.registry.url”配置!!

问题出在 _INTERNAL_KEY_ 和 _INTERNAL_VALUE_
我没有为这两个添加 SCHEMA_REGISTRY_URL，就像我为 _KEY_CONVERTER 和 _KEY_VALUE 一样，我切换回 org.apache.kafka.connect。 json.JsonConverter 用于内部键和值
