编写dockerfile文件，官方推荐名字Dockerfile，使用该名字build的时候就不需要用-f去指定dockerfile

FROM ubuntu

COPY readme.txt /usr/local/readme.txt

# ADD 命令会自动解压
ADD jdk-17.tar.gz /usr/local/java/  
ADD tomcat-10.tar.gz /usr/local/tomcat/ 

ENV MYPATH /usr/local

WORKDIR $MYPATH

ENV JAVA_HOME /usr/local/java/jdk-17.0.1
ENV CLASS_PATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/tomcat/apache-tomcat-10.0.14
ENV CATALINA_BASH /usr/local/tomcat/apache-tomcat-10.0.14
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin

EXPOSE 8080

CMD /usr/local/tomcat/apache-tomcat-10.0.14/bin/startup.sh && tail -F /usr/local/tomcat/apache-tomcat-10.0.14/logs

构建镜像

启动镜像测试

docker run -d -it -p 9090:8080 --name gongyjtomcat -v /home/gongyj/build/tomcat/test/:/usr/local/tomcat/apache-tomcat-10.0.14/webapps/ -v /home/gongyj/build/tomcat/logs/:/usr/local/tomcat/apache-tomcat-10.0.14/logs/ mytomcat 

# 访问测试
root@lsMusKVEqm:/home/mytomcat# curl localhost:9090
