Docker：无法连接到主机的容器
我尝试使用docker-compose来运行一个由2个容器组成的app：akka app和postgresql。 这里是yaml文件：
version: "3" services: api: image: akka-app:latest ports: - "9000:5000" db: image: postgres-db:latest
在docker-compose up命令后，我看到使用docker ps命令启动并运行了容器：
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我在邮递员中找回“拒绝连接”错误。
额外的信息：
- Docker版本17.06.0-ce，build 02c1d87
- docker合成版本
- 1.14.0，build c7bdf9e MacOS Sierra 10.12.5
akka-app容器的networking设置：

更新：
docker构成输出：

问题出在一个安装在我的笔记本电脑上的旧的VirtualBox上。 所以，虽然它被安装，我不能通过localhost访问正在运行的docker容器…你可以阅读更多关于官方docker的网站
从笔记本电脑上卸载VirtualBox后，重新启动Docker应用程序，重新启动terminal会话，使用localhost访问容器是不真实的。
我使用的是从docker-machine ip default获得的IP，而不是本地主机。 但这不是好的方法。
所以再次确保你满足所有的要求。
