背景

在上一个章节中已经介绍了基本的Flink-Operator安装，但是在实际的数据中台的项目中，用户可能希望看到Flink Operator的运行日志情况，当然这可以通过修改Flink-Operator POD的文件实现卷挂载的形势将日志输出到宿主机器的指定目录下，但是这种办法对数据中台的产品不是特别友好，因此我们需要将Operator服务的日志输出到Kafka Appender中；因此我们需要修改Flink Operator的helm中的values配置文件文件，达成我们的目标.

默认情况下Flink Operator不支持Kafka Appender日志输出，为了支持改能力，需要在flink-operator的镜像编译的时候添加kafka依赖，这里小编是在flink-kubernetes-operator模块的pom.xml文件中添加如下配置

<!--kafka版本信息-->
<properties><kafka-clients.version>2.2.0</kafka-clients.version>
</properties>
...
<!--kafka clients依赖-->
<dependency><groupId>org.apache.kafka</groupId><artifactId>kafka-clients</artifactId><version>${kafka-clients.version}</version>
</dependency>

然后对flink-operator重新进行打包编译，重新发布flink-kubernetes-operator镜像即可

日志采集

可以这么理解flink-operator服务是一个flink 任务提交的客户端，在设计的时候会在提交作业的时候允许用户覆盖log4j-console.properties和log4j-operator.properties配置文件，其中如果用户需要采集k8s作业容器的运行日志可以尝试配置log4j-console.properties配置文件，如果是希望查看flink-operator服务本身的日志需要覆盖log4j-operator.properties配置文件。
