java - 如何在 Quarkus 中为 Kafka 使用 TLS？

Question

Kafka guide from Quarkus在 Docker 中本地运行 Kafka 时效果很好。我正在尝试通过将本地 Kafka 服务替换为需要 TLS 的云中托管 Kafka 服务来更改此示例。
有谁知道我如何配置它？在 Quarkus documentation和 Smallrye documentation我没有看到任何属性。
我想在 IBM Cloud 中使用 Kafka 服务。基于 documentation我在 application.properties 中尝试了以下配置:

kafka.bootstrap.servers=broker-0-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-4-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-3-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-5-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-2-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-1-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093
kafka.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="token" password="...";
kafka.sasl.mechanism=PLAIN
kafka.security.protocol=SASL_SSL
kafka.ssl.protocol=TLSv1.2

更新:
我也在下面尝试了 Gunnar 的建议，但它不起作用。当我使用以下 application.properties ...

mp.messaging.outgoing.generated-price.connector=smallrye-kafka
mp.messaging.outgoing.generated-price.topic=prices
mp.messaging.outgoing.generated-price.value.serializer=org.apache.kafka.common.serialization.IntegerSerializer

mp.messaging.outgoing.generated-price.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="token" password="...";
mp.messaging.outgoing.generated-price.sasl.mechanism=PLAIN
mp.messaging.outgoing.generated-price.security.protocol=SASL_SSL
mp.messaging.outgoing.generated-price.ssl.protocol=TLSv1.2

mp.messaging.incoming.prices.connector=smallrye-kafka
mp.messaging.incoming.prices.topic=prices
mp.messaging.incoming.prices.value.deserializer=org.apache.kafka.common.serialization.IntegerDeserializer

mp.messaging.outgoing.prices.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="token" password="...";
mp.messaging.outgoing.prices.sasl.mechanism=PLAIN
mp.messaging.outgoing.prices.security.protocol=SASL_SSL
mp.messaging.outgoing.prices.ssl.protocol=TLSv1.2

kafka.bootstrap.servers=broker-0-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-4-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-3-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-5-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-2-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093,broker-1-8c8cph49mx2p2wqy.kafka.svc01.us-south.eventstreams.cloud.ibm.com:9093

...我收到一个错误:
javax.enterprise.inject.spi.DeploymentException: java.lang.IllegalArgumentException: 无效的 channel 配置 - connector必须为 channel 设置属性 prices在 io.quarkus.smallrye.reactivemessaging.runtime.SmallRyeReactiveMessagingLifecycle.onApplicationStart(SmallRyeReactiveMessagingLifecycle.java:22)
Quarkus 中的 Kafka 目前是否可以使用 TLS？
谢谢

Answer 1

您是否尝试过在 channel 级别指定相关属性？例如。

mp.messaging.outgoing.generated-price.connector=smallrye-kafka
mp.messaging.outgoing.generated-price.topic=mytopic
mp.messaging.outgoing.generated-price.ssl.protocol=...
mp.messaging.outgoing.generated-price.ssl.keystore.location=...
mp.messaging.outgoing.generated-price.ssl.keystore.password=...

当多个主题需要相同的值时，您也可以引用变量。
