1、准备镜像文件 tomcat压缩包，jdk的压缩包！
2、编写dockerfile文件,官方命名Dockerfile,build会自动寻找这个文件，就不需要 -f 指定了！
FROM centos
MAINTAINER ysl<493487822@qq.com>
COPY readme.txt /usr/local/readme.txt
ADD jdk-8u251-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.35-src.tar.gz /usr/local/
RUN yum -y install vim
ENV MYPATH /usr/local
WORKDIR $MYPATH
ENV JAVA_HOME /usr/local/jdk1.8.0_251
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.35
ENV CATALINA_BASH /usr/local/apache-tomcat-9.0.35
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin:$CATALINA_HOME/bin
EXPOSE 8080
CMD /usr/local/apache-tomcat-9.0.35/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.35/bin/logs/catalina.out
3、构建镜像
[root@iz2zeaet7s13lfkc8r3e2kz ysl]# docker build -t diytomcat .
