作为docker的初学者，我正在构建一个简单的web应用程序来注册/登录用户。当我构建映像时，我得到以下错误http status 500-internal server error building web application in docker file，并且我链接了容器（tomcat和mysql）。我还下载并添加了jar文件。不知道哪里出了问题，在谷歌上还找不到任何有用的答案。我的项目中的jsp（一个用于登录，另一个用于注册）文件都出现了相同的错误<
dockerfile（mysql）

FROM mysql

ENV MYSQL_ROOT_PASSWORD="vprodbpass"
ENV MYSQL_DATABASE="accounts"

ADD db_backup.sql docker-entrypoint-initdb.d/accountsdb.sql

dockerfile文件(tomcat:8-jre8)

FROM tomcat:8-jre8

RUN rm -rf /usr/local/tomcat/webapps/*

COPY vprofile-v1.war /usr/local/tomcat/webapps/ROOT.war

EXPOSE 8080
CMD ["catalina.sh", "run"]

创建vrprodb容器

sudo docker run --name vprodb -e MYSQL_ROOT_PASSWORD=vprodbpass -p 3306:3306 -d vprofiledb

创建vproapp容器

sudo docker run --name vproapp --link vprodb:mysql -p 7070:8080 -d vprofileapp

流动容器
