小编给大家分享一下docker中Dockerfile如何自定义tomcat镜像，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
1、创建目录
[root@t-docker chenzx]# mkdir tomcat9 2、在上述目录下touch c.txt，为了演示copy指令的功能
[root@t-docker tomcat9]# touch c.txt3、将jdk和tomcat安装的压缩包拷贝进上一步目录
[root@t-docker tomcat9]# lsatlassian-confluence-6.11.0.tar.gz c.txt jdk1.8.0_65.tar.gz 4、新建Dockerfile文件
[root@t-docker tomcat9]# cat Dockerfile FROM centosMAINTAINER chenzx#把宿主机当前上下文的c.txt拷贝到容器/opt路径下COPY c.txt /opt/container.txt#用ADD指令把java和tomcat压缩包添加到容器中，并自动解压ADD atlassian-confluence-6.11.0.tar.gz /optADD jdk1.8.0_65.tar.gz /opt#安装vim编辑器RUN yum -y install vim#设置工作访问时候的WORKDIR路径，登录落脚点ENV MYPATH /optWORKDIR $MYPATH#配置java与tomcat环境变量ENV JAVA_HOME /opt/jdk1.8.0_65ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarENV CATALINA_HOME /opt/atlassian-confluence-6.11.0ENV CATALINA_BASE /opt/atlassian-confluence-6.11.0ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin#容器运行时监听的端口EXPOSE 8080#启动时运行tomcat#ENTRYPOINT ["/opt/atlassian-confluence-6.11.0/bin/startup.sh"]#CMD ["/opt/atlassian-confluence-6.11.0/bin/catalina.sh","run"]CMD /opt/atlassian-confluence-6.11.0/bin/startup.sh && tail -F /opt/atlassian-confluence-6.11.0/logs/catalina.out 5、构建

以后发版，就在宿主机上的/volume/test里面发版即可，具体测试略。
[root@t-docker tomcat9]# cd /volume/test
[root@t-docker test]# mkdir WEB-INF
[root@t-docker test]# cd WEB-INF/
