六、实战测试（2）--部署Tomcat镜像

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,bulid会自动寻找这个文件，就不需要-f指定了

[root@docker tomcat]# vim Dockerfile

 

FROM centos

MAINTAINER momo<momo@qq.com>

 

COPY readme.txt /usr/local/

 

ADD  apache-tomcat-9.0.6.tar.gz /usr/local/

 

RUN  yum -y install vim

RUN  yum -y install net-tools

RUN  yum -y install java-1.8.0-openjdk

RUN  yum -y install java-1.8.0-openjdk-headless

 

ENV MYPATH /usr/local

WORKDIR $MYPATH

 

ENV JAVE_HOME /usr/local/jdk1.8.0_11

ENV CLASSPATH $JAVE_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

ENV CATALINA_HOME /usr/local/apache-tomcat-9.0.6

ENV CATALINA_BASH /usr/local/apache-tomcat-9.0.6

ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/lib:SCATALINA_HOME/BIN

 

EXPOSE 8080

 

CMD /usr/local/apache-tomcat-9.0.6/bin/startup.sh && tail -F /usr/local/usr/local/apache-tomcat-9.0.6/bin/logs/catalina.out

 

3.构建镜像

[root@docker ~]# docker build -t diytomcat 

4.启动镜像

[root@docker ~]# docker run -d -p 9091:9090 --name momotomecat -v /root/tomcat/web:/usr/local/apache-tomcat-9.0.6/webapps -v /root/tomcat/logs://usr/local/apache-tomcat-9.0.6/logs  diytomcat

5.外网访问

 

 

 

 

至此我们的Tomcat就部署成功
