kafka proxy
v0.3.12
Kafka代理基于Cloud SQL代理的概念。它允许服务连接到KAFKA经纪人，而无需处理SASL/Plain Authentication和SSL证书。
它可以通过在本地机器上打开TCP插座并在使用插座时与相关的Kafka经纪人的连接来工作。元数据中的主机和端口以及从经纪人收到的FindCoordinator响应由本地同行代替。对于发现的经纪人（不配置为Boostrap服务器），本地侦听器是在随机端口上启动的。可以禁用动态的本地侦听器功能，并提供外部服务器映射的其他列表。
代理可以使用SASL/Plain终止TLS流量并验证用户。凭据验证方法是可配置的，并在RPC上使用Golang插件系统。
这些代理还可以使用可插入的方法互相验证，该方法透明了其他Kafka服务器和客户端。当前，实现了服务帐户的Google ID令牌，即代理客户端请求，并发送服务帐户JWT和Proxy Server接收并根据Google JWKS进行验证。
可以限制KAFKA API调用以防止某些操作，例如主题删除或产生请求。

您可以启动一个Kafka-Proxy容器，以尝试使用
docker run --rm -p 30001-30003:30001-30003 grepplabs/kafka-proxy:0.3.12 server --bootstrap-server-mapping "localhost:19092,0.0.0.0:30001" --bootstrap-server-mapping "localhost:29092,0.0.0.0:30002" --bootstrap-server-mapping "localhost:39092,0.0.0.0:30003" --dial-address-mapping "localhost:19092,172.17.0.1:19092" --dial-address-mapping "localhost:29092,172.17.0.1:29092" --dial-address-mapping "localhost:39092,172.17.0.1:39092" --debug-enable
Kafka-Proxy现在可以在localhost:30001 ， localhost:30002和localhost:30003 ，连接到Docker（网络桥接网路网关172.17.0.1 ）的Kafka Brokers广告广告明文在localhost:19092 ： localhost:29092和Localhost：29092和localhost:39092 。
带有/opt/kafka-proxy/bin/的预编译插件的docker映像用<release>-all标记。
您可以启动带有Auth-LDAP插件的Kafka-Proxy容器，以尝试使用

有时，可能不仅有必要验证客户端证书有效，而且还必须为具体用例发布客户端证书DN。这可以使用以下参数来实现：
--proxy-listener-tls-client-cert-validate-subject bool Whether to validate client certificate subject (default false) --proxy-listener-tls-required-client-subject-common-name string Required client certificate subject common name --proxy-listener-tls-required-client-subject-country stringArray Required client certificate subject country --proxy-listener-tls-required-client-subject-province stringArray Required client certificate subject province --proxy-listener-tls-required-client-subject-locality stringArray Required client certificate subject locality --proxy-listener-tls-required-client-subject-organization stringArray Required client certificate subject organization --proxy-listener-tls-required-client-subject-organizational-unit stringArray Required client certificate subject organizational unit
通过设置--proxy-listener-tls-client-cert-validate-subject true ，Kafka代理将检查客户端证书DN字段，以设置为使用--proxy-listener-tls-required-client-*参数。匹配始终是精确的，并在一起使用，所有非空值。例如，要允许country=DE and organization=grepplabs的有效证书，请以下方式配置kafka代理：
kafka-proxy server --proxy-listener-tls-client-cert-validate-subject true --proxy-listener-tls-required-client-subject-country DE --proxy-listener-tls-required-client-subject-organization grepplabs
