Spring Cloud Data Flow Grafana Prometheus not showing stream data

问题

I launch Spring cloud data flow with docker-compose base on this website.

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

I created 3 apps, Source, Processor & Sink.

I ran

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

When I run docker-compose -f ./docker-compose.yml -f ./docker-compose-prometheus.yml up, all my containers start up as specified in the docker-compose.yml and docker-compose-prometheus.yml.

I proceed to register the 3 applications and then create a stream with them.I then run it.

Question 1: The status of the stream is always "Deploying". Shouldn't it be Deployed?

Question 2:

When I click on the "Grafana" icon, it launches the Grafana page but there is no data on it. Why is it so? I am using kafka as my messaging middleware as shown below.

    <artifactId>spring-cloud-stream-binder-kafka</artifactId>

回答1:

I solved this issue adding some dependencies and some entries on properties.

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>

        </dependency>
        <dependency>

            <artifactId>prometheus-rsocket-spring</artifactId>
            <version>0.9.0</version>
        </dependency>

application.properties:
