无法通过使用Docker的Spring应用程序连接到MongoDB和MySQL
我使用像下面这样docker-compose.yml来创build容器。 我是新来的，我试图创build一个nginx容器，tomcat容器与spring的应用程序和两个数据库容器（mongo和mysql）。 在Debian服务器上，Spring应用程序工作，所以我认为问题是configurationdocker集装箱。
nginx: image: nginx links: - web ports: - "80:80" volumes: - ./nginx.conf:/etc/nginx/nginx.conf web: image: tomcat:8.0-jre8 links: - mongo - mysql volumes: - ./bint.war:/usr/local/tomcat/webapps/bint.war - ./tomcat-users.xml:/usr/local/tomcat/conf/tomcat-users.xml mongo: image: mongo:2.7 ports: - "27017:27017" mysql: image: mysql ports: - "3306:3306" environment: MYSQL_ROOT_PASSWORD: rootpass MYSQL_DATABASE: database MYSQL_USER: user MYSQL_PASSWORD: pass
我可以连接到mongo和mysql工具，如workbench和robomongo只是使用localhost和默认端口，但spring的应用程序不能。 我正在使用OSX 10.11.5。

你的spring的应用程序将能够连接使用mongo：27017和mysql：3306。 使用localhost：27017和localhost：3306将无法访问。
另一个选项是docker-compose版本2，默认情况下所有容器将共享同一个networking。
