编写Dockerfile

FROM centos:7
    MAINTAINER This is Tomcat
    #解压jdk包
    ADD jdk1.8.0_231.tar.gz /usr/local/
    #进入工作目录
    WORKDIR /usr/local/
    #重命名
    RUN mv jdk1.8.0_231 java
    #设置环境变量
    ENV JAVA_HOME /usr/local/java
    ENV JRE_HOME /usr/local/java/jre
    ENV CLASSPATH /usr/local/java/lib:/usr/local/java/jre/lib
    ENV PATH /usr/local/java/bin:$PATH
    #解压tomcat包
    ADD tomcat-mod.tar.gz /usr/local/
    #进入工作目录
    WORKDIR /usr/local/
    #重命名
    RUN mv tomcat-mod /usr/local/tomcat
    #暴露端口
    EXPOSE 8080
    #启动tomcat
    ENTRYPOINT ["/usr/local/tomcat/bin/catalina.sh","run"]
