我正在尝试创建一个dockerfile,它是一个kafka客户机,使用合流kafka dotnet。它必须使用kerberos键表来连接,因此我阅读了githubwiki。
这是我的文件:
# ---- dotnet build stage ----

# Kafka SASL directory (keytab is placed here)
RUN mkdir /sasl/
ENV KEYTAB_LOCATION=/sasl/dashboards.service.keytab
COPY --from=build /build/out ${PROGRAM_HOME}
# Copy necessary scripts + configuration
COPY scripts /tmp/
RUN chmod +x /tmp/*.sh && \
mv /tmp/* /usr/bin && \
rm -rf /tmp/*
CMD [ "docker-entrypoint.sh" ]
我的c#消费者配置代码如下:
var consumerConfig = new ConsumerConfig {
GroupId = "command-server" + KafkaHelpers.Servername,
BootstrapServers = KafkaHelpers.BootstrapServers,
AutoOffsetReset = AutoOffsetReset.Latest,
SecurityProtocol = SecurityProtocol.SaslPlaintext,
SaslKerberosServiceName = "kafka",
SaslKerberosKeytab = Environment.GetEnvironmentVariable("KEYTAB_LOCATION"),
SaslKerberosPrincipal = "dashboardserver/<<IPAddress>>"
};
但是当我启动我的客户机时,我得到以下例外
Unhandled exception. Unhandled exception. System.InvalidOperationException: No provider for SASL
mechanism GSSAPI: recompile librdkafka with libsasl2 or openssl support. Current build options: PLAIN SASL_SCRAM OAUTHBEARER
有人能帮我解决问题或给我指出正确的方向吗?我在github上找到了这个,但我似乎无法让它工作。
我不知道如何一步一步地安装librdkafka。

confluent kafka dotnet依赖于librdkafka.redist,默认情况下从该位置加载librdkafka。librdkafka.redist中的构建缺乏对大多数平台的sasl/gssapi支持(由于libsasl2及其所有支持lib的依赖性问题),因此您构建自己的librdkafka版本的方法是正确的,但是您需要告诉confluent kafka dotnet加载您的librdkafka构建,而不是librdkafka.redist构建,你可以打电话来
在调用任何其他合流kafka dotnet api之前。
