ENV CATALINA_HOME /var/tmp/tomcat/apache-tomcat-8.5.8
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin

#打包项目并拷贝到tomcat webapps目录
RUN mkdir /var/tmp/webapp
ADD ./  /var/tmp/webapp
RUN cd  /var/tmp/webapp  && cp /var/tmp/webapp/war/sm_new.war /var/tmp/tomcat/apache-tomcat-8.5.8/webapps/

#开启内部服务端口
EXPOSE 8080

#启动tomcat服务器
CMD ["./var/tmp/tomcat/apache-tomcat-8.5.8/bin/catalina.sh","run"] && tail -f /var/tmp/tomcat/apache-tomcat-8.5.8/logs/catalina.out

使用Dockerfile构建镜像

# docker build -t tomcat .

运行容器

# docker run -it -p 12345:8080 --name=tomcat-test  tomcat
