docker的tomcat镜像

首先编写一个Dockerfile文件

FROM centos
MAINTAINER <>

COPY readme.txt /etc/local/readme.txt

ADD jdk-8u11-linux-x64.tar.gz /usr/local/

ADD apache-tomcat-9.0.27.tar.gz /usr/local/

RUN yum -y install vim

ENV MYPATH /usr/local

WORKDIR $MYPATH

ENV JAVA_HOME /usr/local/jdk1.8.0_11
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.27

ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.27
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin

EXPOSE 8080

CMD /usr/local/apache-tomcat-9.0.27/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.27/bin/logs/catalina.out

镜像编写完 执行 docker build -t diytomcat  .这个点不要忘

添加映射端口和地址

docker run -d -p 9091:8080 --name niurentomcat05 -v /home/niu/tomcat/test:/usr/local/apache-tomcat-9.0.27/webapps/test -v /home/niu/tomcat/tomcatlog/:/usr/local/apache-tomcat-9.0.27/logs diytomcat

构建自己的项目进入test  mkdir WEB-INF  进入web-inf  vim web.xml 

并在test下 构建index.jsp文件  最后访问使用宿主机IP地址：端口/test  就可以访问成功了
