在linux系统上：
我能够启动mysql容器运行 docker run --name articledb -e MYSQL_ROOT_PASSWORD=root -d mysql:latest docker ps输出：

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
032311fbbba6        mysql:latest        "docker-entrypoint.s…"   5 minutes ago       Up 5 minutes        3306/tcp, 33060/tcp   articledb

之后，我尝试运行一个spring引导应用程序，它需要使用 docker run --name articleservice --link articledb:mysql -d articleservice 应用程序属性

spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/article
spring.datasource.username=root
spring.datasource.password=root

它似乎试图启动，但启动失败。服务如何连接到该数据库？
堆栈跟踪错误

[claus@cls articleservice]$ docker run -t --name articleservice --link articledb:mysql articleservice

我想我解决了。我甚至不需要链接容器，只要你知道mysql的ip。至少这是linux的工作方式：
检查mysql容器运行 docker inspect mysqlcontainer | grep IP 将该mysql容器的ip添加到 spring.datasource.url=127.0.0.1:3306/database 跑 mvn clean , mvn install 塑造形象。
在完成这些步骤之后，应该会有结果。
