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 ----

    make install

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。
