Mesosphere DC / OS：在DC / OS上为Prometheus部署Kafka Exporter时需要帮助。如何指定Kafka端点？

Question

我正在尝试使用https://github.com/danielqsj/kafka_exporter/向我的Prometheus公开一些其他的Kafka指标。

我在DC / OS上有5个Kafka实例和1个Prometheus实例。

这是我目前正在尝试做的事情：

我创建了一个exporter.json：

    "id": "kafka-exporter",
    "container": {
        "type": "DOCKER",
        "docker": {
            "image": "danielqsj/kafka-exporter",
            "network": "BRIDGE",
            "portMappings": [
                {
                    "hostPort": 0,
                    "containerPort": 9000
                }
            ]
        }
    },
    "instances": 1,
    "cpus": 1,
    "mem": 64
}

然后运行dcos marathon app add exporter.json

但是，我看到在部署过程中在DC / OS UI stderr日志中出现了此错误：

乍一看，看来我需要在某个地方指定Kafka端点。
