Question

我在此网站上通过docker-compose启动Spring云数据流。

https://dataflow.spring.io/docs/installation/local/docker/

我创建了3个应用程序，即Source，Processor和Sink。

我跑了

export STREAM_APPS_URI=https://dataflow.spring.io/Einstein-BUILD-SNAPSHOT-stream-applications-kafka-maven

当我运行docker-compose -f ./docker-compose.yml -f ./docker-compose-prometheus.yml时，我所有的容器都按照docker-compose.yml和docker-compose-中的指定启动prometheus.yml。

我继续注册这3个应用程序，然后用它们创建一个流，然后运行它。

问题1： 流的状态始终为“正在部署”。不应该部署吗？

问题2：

当我单击“ Grafana”图标时，它会启动Grafana页面，但上面没有数据。为什么会这样呢？我将kafka用作消息传递中间件，如下所示。

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-kafka</artifactId>
        </dependency>

这是我的pom.xml

我解决了这个问题，在属性中添加了一些依赖性和条目。

pom.xml：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-webflux</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud.stream.app</groupId>
            <artifactId>app-starters-micrometer-common</artifactId>
            <version>2.1.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
        </dependency>
        <dependency>
            <groupId>io.micrometer.prometheus</groupId>
            <artifactId>prometheus-rsocket-spring</artifactId>
            <version>0.9.0</version>
        </dependency>

application.properties：

spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.enabled=true
spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.enabled=true
spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.host=prometheus-rsocket-proxy
spring.cloud.dataflow.applicationProperties.stream.management.metrics.export.prometheus.rsocket.port=7001
spring.cloud.dataflow.applicationProperties.stream.management.endpoint.health.show-details=always
spring.cloud.dataflow.applicationProperties.stream.management.endpoint.health.show-components=always
spring.cloud.dataflow.applicationProperties.stream.management.endpoints.jmx.exposure.include=*
spring.cloud.dataflow.applicationProperties.stream.management.endpoints.web.exposure.include=*
