根据Dokerfile文件自定义tomcat镜像

准备jdk和tomcat压缩包

 编写Dockerfile文件

#基于centos镜像来构建
FROM centos
MAINTAINER quan<[e-mail]>
#将宿主机下的文本拷贝到容器/usr/local/路径下
COPY cp.txt /usr/local/cpContainer.txt
#把jdk和Tomcat添加到容器中
ADD jdk-8u181-linux-x64.tar.gz /usr/local/
ADD apache-tomcat-9.0.30.tar.gz /usr/local/
#设置登录落脚点，进入工作目录
ENV MYPATH /usr/local
WORKDIR $MYPATH
#配置jdk和tomcat环境变量
ENV JAVA_HOME /usr/local/jdk1.8.0_181
ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.30
ENV CATALINA_BASE /usr/local/apache-tomcat-9.0.30
ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:$CATALINA_HOME/bin
#运行容器的监听端口
EXPOSE 8080
#指定容器启动时默认的执行命令
CMD /usr/local/apache-tomcat-9.0.30/bin/startup.sh && tail -F /usr/local/apache-tomcat-9.0.30/bin/logs/catalina.out

构建镜像

 docker build -t mytomcat9 .

 run 新构建的tomcat镜像

docker run -d -p 9000:8080 --name shutomcat9 -v /shuquan/myproject/tomcat9/test:/usr/local/apache-tomcat-9.0.30/webapps/test -v /shuquan/myproject/tomcat9/tomcat9logs/:/usr/local/apache-tomcat-9.0.30/logs --privileged=true mytomcat9
