Question

我尝试使用docker-compose来运行一个包含2个容器的应用程序：akka app和postgresql。这是yaml文件：

version: "3"
services:
  api:
    image: akka-app:latest
    ports:
        - "9000:5000"
  db:
    image: postgres-db:latest

在docker-compose up命令之后，我看到容器已启动并正在使用docker ps命令运行：

CONTAINER ID        IMAGE                                COMMAND                  CREATED             STATUS              PORTS                    NAMES
65326e5a9677        akka-app:latest                      "java -cp /..."   40 minutes ago      Up 23 seconds       0.0.0.0:9000->5000/tcp   samplecompose_api_1
1f86273c4f9a        postgres-db:latest                   "docker-ent..."   19 hours ago        Up 23 seconds       5432/tcp                 samplecompose_db_1

但是当我尝试通过GET请求从主机访问 akka-app 到0.0.0.0:9000/status或localhost:9000/status时，我回来了＃34;拒绝连接＆＃ 34;邮递员的错误。

额外信息：

Docker版本17.06.0-ce，build 02c1d87
docker-compose version
1.14.0，build c7bdf9e MacOS Sierra 10.12.5

问题出在安装的旧VirtualBox上，谁知道我的笔记本电脑何时出现。因此，在安装时，我无法通过localhost访问正在运行的docker容器... 您可以在官方泊坞网站上read more了解此信息

从笔记本电脑卸载VirtualBox后，重新启动Docker应用程序并重新启动终端会话，使用localhost来访问容器是不真实的。

我使用的是docker-machine ip default中使用的IP，而不是本地主机。但这不是好方法。

请再次确保您符合所有要求。

Docker：无法从主机
