如何在Docker容器中部署Spring Boot War应用程序以及MySql数据库

Question

我试图将WAR spring boot应用程序与MySql数据库一起部署在Docker容器中。

我的Spring Boot应用程序有一个单独的dockerfile，而MySql有一个单独的dockerfile。 MySql和Spring Boot应用程序位于单独的容器中。

当我尝试链接容器并运行它时，会显示类似mysql.jdbc.exception.CommunicationsException的异常。

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启动应用程序的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

此错误在Kitematic GUI容器日志中显示
