如何在docker容器中部署SpringBootWar应用程序和MySql数据库

我正试图在Docker容器中与MySql数据库一起部署我的WARspring boot应用程序

我的spring boot应用程序有一个单独的dockerfile，MySql有一个单独的dockerfile。MySql和spring boot应用程序位于不同的容器中

当我尝试链接容器并运行时，它会显示一个异常，如

mysql.jdbc.exception.CommunicationsException

FROM tomcat:8.0.51-jre8-alpine

COPY demo-0.0.1-SNAPSHOT.war /usr/local/tomcat/webapps/service.war

CMD ["catalina.sh","run"]

这是我的Spring boot应用程序Dockerfile

 FROM mysql:8

 EXPOSE 3306

 ENV MYSQL_ROOT_PASSWORD root

 ENV MYSQL_DATABASE testDB[This the screen shot of the error][1]

这是我的Mysql Dockerfile

我正在使用此命令链接容器。

docker-run-t--name-springservices--link-mysql-docker-container:mysql-p 8081:8080-services

此错误显示在Kitematic GUI容器日志中
