我运行启动tomcat8服务器的docker镜像,但它没有启动

我有Docker图像,我从docker文件创建.当我运行映像时,它能够运行tomcat服务器,然后命令提示符返回.这意味着该过程终止,我认为容器停止.所以当我看到http://localhost:8080时,没有出现tomcat页面.所以我无法找到实际的问题.我实际上试图构建自定义java8,tomcat8和maven作为环境,我想在该tomcat服务器中部署我的maven项目.Bellow是用于创建图像的Dockerfile FROM scratch FROM ubuntu:16.04 RUN mkdir /opt/java8 RUN mkdir /opt/tomcat8 RUN mkdir /opt/maven3 ENV JAVA_HOME /opt/java8 ENV CATALINA_HOME /opt/tomcat8 ENV M2_HOME /opt/maven3 ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin:$M2_HOME/bin ADD jdk1.8.0_112 /opt/java8 ADD apache-tomcat-8.0.38 /opt/tomcat8 ADD apache-maven-3.3.9 /opt/maven3 EXPOSE 8080 CMD ["startup.sh", "run"] 我把3个文件夹的java,tomcat,maven放在Docker文件附近,这样就添加了. 现在,当我构建图像并运行图像时,会出现波纹管日志. root@dhavalbhoot:/home/veni/Documents/dhaval_bhoot/docker_images/tomcat1# docker run -it -p 8080:8080 dhaval/tomcat:8.0.38 输出： Using CATALINA_BASE: /opt/tomcat8 Using CATALINA_HOME: /opt/tomcat8 Using CATALINA_TMPDIR: /opt/tomcat8/temp Using JRE_HOME: /opt/java8 Using CLASSPATH: \#/opt/tomcat8/bin/bootstrap.jar:/opt/tomcat8/bin/tomcat-juli.jar Tomcat started. root@dhavalbhoot:/home/veni/Documents/dhaval_bhoot/docker_images/tomcat1# 这样提示会回来,我在浏览器http://localhost:8080中检查tomcat页面没有出现所以帮我解决问题.
