Question

我使用提供的docker-compose.yaml文件启动了Spring Cloud Dataflow服务器，并定义了一个简单的流：http | log

现在，我想从主机上向HTTP源发送一些数据，但是我找不到正确的服务器地址和端口。

我想

curl -X POST -d 'data to be sent' http://localhost:8080

http://localhost:8080必须使用什么才能使它正常工作？

这是我的docker-compose.yaml文件：

version: '3'

services:
  rabbitmq:
    image: rabbitmq:3.7
    expose:
      - "5672"
  zookeeper:
    image: wurstmeister/zookeeper
    expose:
      - "2181"
  dataflow-server:

  app-import:
    image: springcloud/openjdk:latest
    depends_on:
      - dataflow-server
    command: >

        while ! nc -z dataflow-server 9393;
        do
          sleep 1;
        done;
        wget -qO- 'http://dataflow-server:9393/apps' --post-data='uri=http://bitt.ly/Einstein-SR2-stream-applications-rabbit-maven&force=true';
        echo 'Stream apps imported'
        wget -qO- 'http://dataflow-server:9393/apps' --post-data='uri=http://bitt.ly/Dearborn-SR1-task-applications-maven&force=true';
        echo 'Task apps imported'"

    - "9000-9010:9000-9010"

在skipper-server中定义的docker-composer.yaml容器中执行组成Spring Cloud Data Flow中流的java应用程序。

这意味着跳过服务器部分中的端口映射是相关的：

  skipper-server:
    image: springcloud/spring-cloud-skipper-server:${SKIPPER_VERSION:?SKIPPER_VERSION is not set!}
    container_name: skipper
    ports:
    - "7577:7577"
    - "9000-9010:9000-9010"

这意味着端口7577和9000-9010已映射到主机端口。

为防止http源选择随机端口，流定义必须如下所示：

http --server.port=9000 | log

现在，以下各项可以正常工作：

curl -H "Content-Type: application/json" -X POST -d '{"id":"1","temperature":"100"}' http://localhost:9000

如何在Docker容器中访问Spring Cloud Data Flow Server的http源？
