Question

我无法在Confluent Kafka-Connect映像中使用AWS MSK TLS终端节点，因为它超时创建/读取主题。通过PlainText端点时，效果很好。

我尝试引用docker映像上可用的jks存储路径仍然无法正常工作，不太确定我是否缺少任何其他配置。因此，从我从AWS文档中读取的内容来看，Amazon MSK代理使用公共AWS Certificate Manager证书，任何信任Amazon Trust Services的信任库也都信任Amazon MSK代理的证书。

**Error:**
org.apache.kafka.connect.errors.ConnectException: Timed out while checking for or creating topic(s) '_confluent-command'. This could indicate a connectivity issue, unavailable topic partitions, or if this is your first use of the topic it may have taken too long to create.

附加我正在使用任何帮助的kafka-connect配置会很棒：）

我在/ usr / lib / jvm / zulu-8-amd64 / jre / lib / security / cacerts的docker映像中使用了Java cacerts作为信任库。使用keytool，如果您查看证书：

keytool --list -v -keystore /usr/lib/jvm/zulu-8-amd64/jre/lib/security/cacerts|grep Amazon

它将列出Amazon CA。

然后我使用以下命令启动容器：

docker run -d \
  --name=kafka-connect-avro-ssl \
  --net=host \
  -e CONNECT_BOOTSTRAP_SERVERS=<msk_broker1>:9094,<msk_broker2>:9094,<msk_broker3>:9094 \
  -e CONNECT_REST_PORT=28083 \
  -e CONNECT_GROUP_ID="quickstart-avro" \
  -e CONNECT_CONFIG_STORAGE_TOPIC="avro-config" \
  -e CONNECT_OFFSET_STORAGE_TOPIC="avro-offsets" \
  -e CONNECT_STATUS_STORAGE_TOPIC="avro-status" \
  -e CONNECT_KEY_CONVERTER="io.confluent.connect.avro.AvroConverter" \
  -e CONNECT_VALUE_CONVERTER="io.confluent.connect.avro.AvroConverter" \
  -e CONNECT_KEY_CONVERTER_SCHEMA_REGISTRY_URL="<hostname of EC2 instance>:8081" \
  -e CONNECT_VALUE_CONVERTER_SCHEMA_REGISTRY_URL="http://<hostname of EC2 instance>:8081" \
  -e CONNECT_INTERNAL_KEY_CONVERTER="org.apache.kafka.connect.json.JsonConverter" \
  -e CONNECT_INTERNAL_VALUE_CONVERTER="org.apache.kafka.connect.json.JsonConverter" \
  -e CONNECT_REST_ADVERTISED_HOST_NAME="<hostname of EC2 instance>" \
  -e CONNECT_LOG4J_ROOT_LOGLEVEL=DEBUG \
  -e CONNECT_SECURITY_PROTOCOL=SSL \
  -e CONNECT_SSL_TRUSTSTORE_LOCATION=/usr/lib/jvm/zulu-8-amd64/jre/lib/security/cacerts \
  -e CONNECT_SSL_TRUSTSTORE_PASSWORD=changeit \
  confluentinc/cp-kafka-connect:latest

这样，它成功启动了。我还能够连接到容器，创建主题，在容器内生产和消费。如果您无法创建主题，则可能是网络连接问题，可能是连接到MSK群集的安全组的安全组问题，从而阻止了端口2181和TLS端口9094。

使用Kafka-Connect通过SSL连接到MSK时出现问题
